Abstract

This project involves creating and developing a video game where output is displayed on a LED matrix. Development of the relevant hardware/software components and modules was divided among 4 team members. Each team member lead or significantly contributed to the development of multiple components. The project was focused on not only technical skills, but team building as well, and working with others towards a common goal.

This project provides us hands-on experience using freeRTOS in a real application. Our objective is to apply what we have learned in class and develop a video game using our SJtwo Board. In this project, we create different tasks for different modules, such as a display task for displaying the game objects on LED matrix, a tower task for detecting nearby enemies and shoot them, a stage task to manage each game stage etc. We need to use both cooperative scheduling and preemptive scheduling technique to make this video game run efficiently. In order to make this game run in a particular sequence, we also need to synchronize and sequentialize each task by setting the task priorities carefully and using binary semaphore correctly.

Introduction and Objectives

Alien Invasion

Like most traditional tower defense games, the player needs to defend our planet from the invasion of aliens. The gameplay can be split into 2 phases, Combat Phase and Intermission Phase. During the intermission phase, the player can place different kinds of towers strategically that will attack the invading aliens from entering into our homeland by shooting the enemies. During the combat phase, spaceships follow the path and try to land on our planet. If any enemy spaceship reaches the end of the path, then the player loses. If there are no more spaceships remaining in a wave, the player can build a stronger tower that has a longer attack range and can shoot a more powerful laser to the spaceships in the next wave. The player wins the game after surviving 5 waves of attack.

This game can be separated into 4 different modules:

Game Logic: SJtwo Board - handles the game logic. (For example: detect and shoot nearby enemies, switch between intermission phase and combat phase)
Display: Adafruit 64x64 LED matrix - displays the animation of the game.
Gamepad Controller: The input of this game. The gamepad controller consists of a joystick and two buttons. The player can use the joystick to move the cursor and decide where to place the towers. After that, the user needs to press the black button to select and confirm the location of the towers. If the player knows that he/she has made a mistake in the middle of the game and will eventually lose the game, the player can press the red button and restart the game.
Sound: MP3 Decoder and speaker. Players can enjoy cool music during the game. This is done on an additional SJtwo board, which will play the song on repeat.

Game Design

Game Rules

Gameplay is split into 2 phases:
Intermission - Player sets up tower locations
Combat - Player watches round unfold

During the Intermission Phase:

The player places towers strategically around the enemy path.
The number of towers is fixed per round
Towers can only be placed in marked areas that do not lie on a path
The built-in software will find a valid tower location and move the cursor there automatically according to joystick input.
There are 5 types of towers (increasing damages, ranges, and of different colors). Each tower type depends on the current wave.

During the Combat Phase:

Enemies will enter the gameplay area at one end of the path and attempt to reach the other end
Towers will automatically engage enemies when they come within range
Towers shoot until the enemy is either dead or out of range
Tower proximity is 8 directions (top, bot, left, right, top-right, top-left, bot-left, bot-right) and 1 unit (not necessarily 1 pixel) away
Enemies that reach the end of path while being alive will result in losing the game.
If any spaceship reaches the end of the path, the player loses and the game ends
The round is over when the player loses or a set number of enemies have been defeated.

Dashboard (Combat Phase)

There will be a dashboard on the LED matrix that displays basic UI information:
Intermission Phase:

Time until combat phase
Current wave number
Number of towers left that you can still place

Combat Phase:

Current wave number
Number of enemies still remaining in the current wave

Game Objectives

There are 5 waves (rounds) total.
In each round, enemies in various amounts, groupings, and health levels (armor) pass through the path.
If any enemies reach the end of the path, then the user loses.
After each round, the user will be able to place more towers which are stronger and can shoot farther.
Each round will have waves of enemies that are more difficult to stop.
The user needs to carefully place their towers such that it will have a maximum number of opportunities to shoot at the enemies.
The trick is that the user will need to preserve early level towers, otherwise they will not have enough room to place the high level towers in the optimal location.

How To Play

The gamepad controller consists of a joystick and two buttons.

Joystick - move the cursor and decide where to place the towers.
Black button - select and confirm the location of the towers.
Red button - restart the game (If the player knows that he/she has made a mistake in the middle of the game and will eventually lose the game, the player can press the red button and restart the game.)

During the Intermission Phase:

The player places towers strategically around the enemy path by using the joystick to move the cursor and pressing the black button to select the location of the towers.
The player needs to place all remaining towers under 45 seconds.

During the Combat Phase:

Cheer on your towers and watch them defend Earth from the alien invasion!

Hardware Design - Electrical

Overview

At a high level hardware integration requirements fell into two categories:

1. Reduce risk of unreliable cable connections and eliminate possibility of damage to components through unexpected disconnections, power surges, etc.
2. Provide a more fluid physical interface for the user to interact with the game via hardware

To accomplish these goals, two boards were designed: a breakout board and a gamepad controller. The breakout board serves as a connection hub between all system hardware components; power, the RGB matrix, the SJTWO board, etc. while the joystick provides a cleaner package to present the user with the games inputs. The diagram below shows the relationship between the main subsystems:

All board designs were done using EAGLE and manufactured by JLCPCB. Both boards were only two layers and used passive components for the most part.

Breakout Board Design

The breakout board design requirement was to interface all external hardware components with the embedded system (SJTWO). The hardware connections are:

1. The 64x64 RGB Matrix
2. Output power to the RGB Matrix
3. User game controller (see next section)
4. Input power supply (5V)
5. The SJTWO embedded system

Wrong silkscreen/not enough room near power input.	Power input silkscreen too small, part too big for 3.3V LED to fit	0.1	Resolved Rev 0.2
Linear regulator not needed.	The schematic for the SJTWO board labels the input voltage pin as VIN RAW, which is different than the label on the optional input port. They are both the same, so this input feeds directly into the on-board 3.3V regulator. Essentially we're driving the regulator with the same voltage it outputs which just won't work well.	0.1, 0.2	UNRESOLVED

Gamepad Hardware Design

The gamepad board design requirement was to provide a more packaged interface for the user to interact with the game.

Hardware Design (Mechanical)

Only a few mechanical components were needed for this project. Namely simple brackets for mounting electrical hardware to the RGB matrix and displaying the matrix itself. All CAD designs were done using Onshape, a free CAD tool that can be used entirely through your web browser.

For displaying the RGB matrix, two brackets were 3D printed to prop it up. Their STL files can be found under our source repository.

Mounting bracket design used to prop up the RGB matrix

Hardware Integration

RGB LED MATRIX

The LED matrix that we use is 64 pixels by 64 pixels and is controlled through a 12-pin header consisting of the following pins:

Five Mux pins (A,B,C,D,E) for Row Selection
- In order to select a specific row of the LED matrix, we need to control the output level of each mux pin. Since the LED matrix light up two rows of LEDs at one time, we can only select 1 out of 32 rows.
Two sets of RGB pins (R1,G1,B1,R2,G2,B2) for Color Selection
- Since we are driving two rows of LED matrix at once, we need 2 sets of RGB pins. One set is used to control the color pixels of the upper half of the display and the other set for the bottom half of the display.
Output Enable Pin (OE)
- Output Enable (OE) pin is used to turn on or off the LEDs of the current row.
Latch Pin (LAT)
- Latch pin is used to prevent the data being shifted into the shift registers and tells the shift register when it is time to switch to newly entered data.
Clock Pin (CLK)
- triggers a shift on the shift registers

All these pins are required to display a specific color on a specific pixel of the LED matrix display.

Pin Connections between SJtwo Board and REG LED Matrix

LED Matrix - Row Scanning

Apparently, it is impossible to driver all 4096 LEDs all at one time and thus, we can only drive two rows of LEDs at a time (one row on the upper half of the display and another row on the lower half of the display). By refreshing the LED matrix two rows at a time in a fast frequency, we can display all the game objects with animation on the LED matrix.

Joysticker controller

The joystick that we use is the product from Adafruit, the Analog 2-axis Thumb Joystick. This 2-axis Thumb Joystick provides the following pins:

Two ADC pins
1. In order to control the tower location, we need to control the Joysticker, since the direction has four: Up, Down, Left, Right, we use the Y and X-axis to implement this function.
Three GPIO pins
1. In order for selecting for the tool we need two GPIO pin for button and 1 GPIO pin for controlling the LED on the JOY STICKER controller

Pin configuration

MP3 Decoder

The MP3 decoder that we use is Sparkfun’s vs1053 shield MP3 decoder which is the board based on the vs1053b chip.

MP3 Decoder Module Pinout

MP3 Decoder Pin Table

Three SPI pin

In order to communicate with the mp3 decoder with SJtwo Board, we choose the SPI as the protocol to control the decoder. Hence, we need the one pin SCK0 (clock), one pin MOSI(Master In Slave Out) and one pin (Master Out Slave In).

Four GPIO pin for the decoder

There are four major GPIO pin for DREQ(Data Request Pin), Reset, CS(Chip Select), XDCS(Data Chip Select), this 4 GPIO pin is how we transfer data and send the command to activate the mp3 decoder work with SJ2 Board.

Software Design

RGB LED Matrix

RGB Data Element

All the LED Matrix data are stored in a buffer with its size equal to 32 by 64. Each element in this buffer store the color of two pixels, one pixel from the upper half of the display and one pixel from the lower half of the display.

In order to display the gaming objects in animation, we need to refresh the display by displaying the color pixels on each row one by one very fast. Below is a simple flowchart that describes the process of refreshing the display.

Loop through each row of the LED display

Select Row (By controlling the output level of 5 mux pins, we can select one row at a time)
Disable the LED Display output (Turn off the LEDs of the current row of the display)
Unlatch the Data
Clock in Data for each column(Store the color of each pixel inside display_matrix buffer)
Latch the Data
Enable the LED Display output (Display the color of each pixel of the current row)
Delay for a 100us (Increase the light intensity of the LEDs by delay a short amount of time)
Disable the LED Display output (Turn off the LEDs of the current row of the display)

void refreshDisplay(void) {
  for (uint8_t row = 0; row < LEDMATRIX_HALF_HEIGHT; row++) {

    select_row(row);
    led_matrix__disable_output(); // gpio__set(OE);
    led_matrix__unlatch_data();   // gpio__set(LAT);
    led_matrix__clock_in_data(row);
    led_matrix__latch_data();    // gpio__reset(LAT);
    led_matrix__enable_output(); // gpio__reset(OE);
    delay__us(100);              // Change Brightness
    led_matrix__disable_output();
  }
}

void led_matrix__clock_in_data(uint8_t row) {
  /* Clock in data for each column */
  for (uint8_t col = 0; col < LEDMATRIX_WIDTH; col++) {
    
    /* Set all the RGB pins as low*/
    LPC_GPIO1->PIN &= ~(0x1 << R1.pin_number | 0x1 << G1.pin_number | 0x1 << B1.pin_number);
    LPC_GPIO2->PIN &= ~(0x1 << R2.pin_number | 0x1 << G2.pin_number | 0x1 << B2.pin_number);

    /* Set the RGB pins as High or Low depends on the data stored inside the buffer */
    LPC_GPIO1->PIN |= ((((display_matrix[row][col] >> 0) & 0x1) << R1.pin_number) |
                       (((display_matrix[row][col] >> 1) & 0x1) << G1.pin_number) |
                       (((display_matrix[row][col] >> 2) & 0x1) << B1.pin_number));

    LPC_GPIO2->PIN |= ((((display_matrix[row][col] >> 4) & 0x1) << R2.pin_number) |
                       (((display_matrix[row][col] >> 5) & 0x1) << G2.pin_number) |
                       (((display_matrix[row][col] >> 6) & 0x1) << B2.pin_number));

    gpio__set(CLK);
    gpio__reset(CLK);
  }
}

MP3 Decoder

The MP3 deocder is executed with the mainly two task: read task and play task. The reader task would read data from the sd card and sned queue data for the player task to play music.

MP3 Decoder Module API

Read Task
Loop through each row of the LED display

Queue sned the target filename
Queue receive the target name
Find the mp3 file name is exit or not
Open the file(fopen)
Read data store to the buffer(Binary)
Sent the data from bufder with queuesend API

Play Task

Receive the data of the song from the queue, and use the receiving data and sent the command to make decoder to play music.

Read Task
Loop through each row of the LED display

Queue receive the data(music)
disable the chip select
Check the DREQ pin to know is ready or not
exchange the data to the decoder to play the music
Check the DREQ pin to know is ready or not
disable the chip select

JOY STICKER

The JOY_STICKER is using the task to pool the ADC channel data to get the direction from the Joysticker.

Loop through each time to poll the enum type data to get direction

Receiving the data from two ADC channel(5=x, 4=y)
Comparing which one has higher absolute data
If (X > Y == YES) ,then we go to the loop to compare It's closer to Right or Left
If (X > Y == YES && Right > LEFT == YES), then the status is Right
If (X > Y == YES && Right > LEFT == NO), then the status is Left
If (X > Y == NO) ,then we go to the loop to compare It's closer to Up or Down
If (X > Y == NO && Up > Down == YES), then the status is Up
If (X > Y == NO && Up > Down == NO), then the status is Down

Technical Challenges

Game Map (2D array) to LED matrix (2D pixels) Conversion

Issue:

The game map (consisting of the path as well as all of the active enemies and towers) is managed through the use of a 2D char array.
In order to display each object on the LED matrix, there needs to be a mechanism that converts the object along with its 2D array location to a row/column on the LED matrix.
An algorithm to do this conversion is not as straightforward as it may appear. This is because objects stored in the array take up more/less display space than what is available on the LED matrix.

Solution:

In order to align the array locations with the LED matrix pixel locations, some areas on the 2D array needed to be marked as "ignore".
If each array location is not carefully correlated to a specific pixel location, then there would be issues where objects are displayed overlapping each other on the LED matrix (or simply displayed in the wrong spot).
There were some simple algorithms that used math to help implement this conversion.
However, a LUT is what was primarily used. It was not efficient in terms of code size, it took over 500 lines of code.
But it was an effective solution and allowed us to easily decide exactly where each pixel of each object would be displayed.

LED Matrix Flickering Issue

Issue: While we are developing the game, we notice that some color pixels are turned on when they are supposed to be off.

Investigation/Solution:

See Known Breakout PCB Issues as a possible cause. It's possible the SJTWO board is getting inconsistent power.
Refreshing the matrix should not be handled by an interrupt and not a task. The task should only push new display data and not have direct control of the matrix. Keeping the refresh interrupt driven would keep the refresh rate more consistent by removing the process being context switched out mid update.

MP3 Decoder - SJtwo Board SPI Selection

Issue:

The mp3 decoder1053b's document is a kind of confusing for the mode when 1032b have several modes
It's hard to know the configuration is successful or not.

Solution:

Doing the survey on the GitHub is really important. For example, using the sin wave and hello binary example to test how the Initialization and HZ parameter would save a lot of time.Moreover, in the document from the vs1053b, we could use the binary file line "hello", "sine wave" function for testing.
Besides, we also have to be careful to check the SJBoard's SPI because of the SD card reader is using for reading SDcard. Hence, I would recommend using other

SPI0, SPI1 instead of using SPI2.

Conclusion

We successfully designed and implemented the video game "Tower Defense In Space". All of our team members now have a better understanding of how to use FreeRTOS to handle the synchronization of multiple tasks and to communicate with multiple hardware components in an embedded application system. After completing this project, we learned how to manage a project on a tight schedule. Starting from purchasing hardware components, developing hardware drivers and game logic and then integrating all of the drivers and APIs into the game logic. Furthermore, all of us are now better at coding and debugging code. For a game design project like this, we learned that it's not always best to assign tasks independently between the team members. We learned that this type of project would benefit moreso from pair programming and other cooperative tasks that enable collaboration between teammates. Otherwise, project tasks may be done in such a way that they only work for 1 specific configuration, and wouldn't help progress towards the end goal of the integrated system. We also learned that not every day was going to be perfect, but as long as we never gave up and worked hard, then the final result would not be disappointing!

We would like to say thank you to Prof. Preet and all the ISAs for their precious suggestions and assistance during the development of this project!

Advice for Future Students

Source Control

Unless everyone in your group is comfortable using source control, don't use it. It will likely end up costing you time in the long run.

Start working on your LED Matrix driver ASAP

The first 64x64 LED Matrix that we got from Sparkfun suffers from a serious flickering issue. After spending for a week trying to debug what causes the flickering issue, we still have no idea whether it is a hardware issue or software issue. Later, we borrow another LED matrix from a student of our class and test our code. With the other student's LED matrix (we use our own power supply and ribbon cables), there is no flickering issue at all. According to some online resources, some matrix vendors scatter the selected rows and columns differently. It is possible that your designed driver may only work on some LED matrix vendors' displays.

-The hardware integration PCB was designed with two goals:  <br>
-'''1. Minimize the footprint of the onboard electronics''' <br>
-'''2. Minimize the chances of wires disconnecting, during drives'''  <br>
-To accomplish these goals,
-The board consisted of 4 layers:

-In order
+During the <b>Intermission Phase</b>: <br>
+#The player places towers strategically around the enemy path. <br>
+#The number of towers is fixed per round <br>
+#Towers can only be placed in marked areas that do not lie on a path <br>
+#The built-in software will find a valid tower location and move the cursor there automatically according to joystick input. <br>

+**In order to select a specific row of the LED matrix, we need to control the output level of each mux pin. Since the LED matrix light up two rows of LEDs at one time, we can only select 1 out of 32 rows.
+*Two sets of RGB pins (R1,G1,B1,R2,G2,B2) for Color Selection
+**Since we are driving two rows of LED matrix at once, we need 2 sets of RGB pins. One set is used to control the color pixels of the upper half of the display and the other set for the bottom half of the display.
+*Output Enable Pin (OE)
+**Output Enable (OE) pin is used to turn on or off the LEDs of the current row.

+Apparently, it is impossible to driver all 4096 LEDs all at one time and thus, we can only drive two rows of LEDs at a time (one row on the upper half of the display and another row on the lower half of the display).

+=== Game Map (2D array) to LED matrix (2D pixels) Conversion ===
-===== <font color="FF0000"> '''''ADC Supply Voltage''''' </font>=====
+Issue:
+# The game map (consisting of the path as well as all of the active enemies and towers) is managed through the use of a 2D char array.
+# In order to display each object on the LED matrix, there needs to be a mechanism that converts the object along with its 2D array location to a row/column on the LED matrix.
+# An algorithm to do this conversion is not as straightforward as it may appear. This is because objects stored in the array take up more/less display space than what is available on the LED matrix.
+Solution:
+# In order to align the array locations with the LED matrix pixel locations, some areas on the 2D array needed to be marked as "ignore". <br>
+# If each array location is not carefully correlated to a specific pixel location, then there would be issues where objects are displayed overlapping each other on the LED matrix (or simply displayed in the wrong spot).
+# There were some simple algorithms that used math to help implement this conversion. <br>
+# However, a LUT is what was primarily used. It was not efficient in terms of code size, it took over 500 lines of code. <br>
+# But it was an effective solution and allowed us to easily decide exactly where each pixel of each object would be displayed.

+We successfully designed and implemented the video game "Tower Defense In Space". All of our team members now have a better understanding of how to use FreeRTOS to handle the synchronization of multiple tasks and to communicate with multiple hardware components in an embedded application system. After completing this project, we learned how to manage a project on a tight schedule. Starting from purchasing hardware components, developing hardware drivers and game logic and then integrating all of the drivers and APIs into the game logic. Furthermore, all of us are now better at coding and debugging code.
-* '''Front-middle Distance Sensor'''
+For a game design project like this, we learned that it's not always best to assign tasks independently between the team members. We learned that this type of project would benefit moreso from pair programming and other cooperative tasks that enable collaboration between teammates. Otherwise, project tasks may be done in such a way that they only work for 1 specific configuration, and wouldn't help progress towards the end goal of the integrated system. We also learned that not every day was going to be perfect, but as long as we never gave up and worked hard, then the final result would not be disappointing!

+==== Start working on your LED Matrix driver ASAP ====
+The first 64x64 LED Matrix that we got from Sparkfun suffers from a serious flickering issue. After spending for a week trying to debug what causes the flickering issue, we still have no idea whether it is a hardware issue or software issue. Later, we borrow another LED matrix from a student of our class and test our code. With the other student's LED matrix (we use our own power supply and ribbon cables), there is no flickering issue at all. According to some online resources, some matrix vendors scatter the selected rows and columns differently. It is possible that your designed driver may only work on some LED matrix vendors' displays.
