Writing the LED Matrix driver was a challenge. We didn't get any material with the display. We had to search online and got a couple of websites explaining about the display. We also had help from the previous year's projects. After all the knowledge we could gain, we started writing the driver. We were successfully able to write the refresh display driver which uses a 32x64 matrix buffer that stores multiple 6-bit color data. The driver worked fine but there was one small issue. 32nd and 64th rows were much brighter than the others. After some testing, we figured out that we weren't clearing the last rows in each half of the display. After resolving that, our refresh display driver worked flawlessly.

=== Title Screen and Game Over Screen===
When we tried to write the code for the title and game over screens, we wanted to make the design/font more eye-catching like most arcade-games are. However, coding each letter with the fancy font proved to be challenging and lengthy. Initially, we were having a function that would take the starting coordinate of where the letter should appear. To display the rest of the letter, we would have had to code the exact position of every pixel we wanted to turn on. This approach worked fine for small designs such as our spaceship, bullets, enemy ships and other minimal moving elements of the game. For gigantic letters with fancy fonts, we used 2-Dimensional array of size 64x64, and input the values using Notepad++ and its handy column selection feature. Then it was just a matter of reading from this array to display the letters.

Space Impact.png

Abstract

Space Impact is a classic game from the days of the Nokia era. Our objective is to design a game in which a player is prompted to protect a spaceship from incoming missiles by moving the ship up and down. The player will also have the ability to fire back at the incoming enemies. Taking damage from the enemy will reduce the health of the spaceship and zero health will lead to the game over screen. The game involves a user controlling a spaceship through an accelerometer, guiding the spaceship across many enemy spacecraft and obstacles. These obstacles are generated randomly and appear from the right-hand side of the screen. The player shoots the obstacles with bullets by pressing a button clearing a path for him or herself. The game starts on the press of the button and ends when the players runs out of health by taking too many hits. The objective of the game is to survive as long as possible acquiring as many points as he or she can.

Design & Implementation

Hardware Design

The hardware design in this project involved an LED Matrix, MP3 Audio Decoder, SJTwo Board along with its on-board accelerometer.

LED Matrix

The main component in our hardware design is the 64x64 LED Matrix. It uses 5 data lines (A,B,C,D,E) which is used for row selection of LED Matrix. R1,G1,B1 control the colors of the upper half of the LED Matrix and R2,G2,B2 control the lower half the matrix.The CLK signal is used to indicate the arrival of a bit of data. Each time the clock goes high, a bit of data is clocked in for the current row. OE (output enable) switches the LEDs off when transitioning from one row to the next. The LAT (latch) signal marks the end of a row of data.The following are its technical specifications:

  • Module size: 192 x 192mm
  • Pixel pitch: 3mm
  • Pixel density: 111,111 pixels/ sqm
  • Pixel resolution: 64 pixels (W) x 64 (H) pixels
  • Max power consumption: 18W
  • Module thickness: 14.66mm (without magnet), 26.55mm (with magnet)
  • Weight: 0.31kg
  • Scan mode: 1/ 16 scan
  • Power Supply: 5V regulated power input, 4A max

MP3 Audio Decoder

We also used an audio decoder for the in-game sound effects. This module is a simple MP3 player device based on high quality MP3 audio chip MH3028M. It has 4 pins namely Vcc, GND, Rx, and Tx. MCU can send commands to module through UART port to control MP3 playback.

Accelerometer

The SJTwo board has its own accelerometer on-board. It has the MMA8452Q, 3-axis, 12-bit/8-bit digital accelerometer. It has an I2C digital output interface.

On-board accelerometer


Hardware Interface

Our design for LED control was based on the below simplified block diagram. We are using the SJTwo board GPIO pins for turning on and off an LED in the LED matrix. R1 G1 B1 is used to control the colors of LEDs in the top half of the matrix (0-31 rows) and R2 G2 B2 in the bottom half of the matrix (32-63 rows). GPIO were also selected for the CLK, LAT and OE purposes. ABCDE pins are used for row selection. Each pin is made high or low based on the requirement. Using these pins we can form our LED animation based on transmission pattern.

Software Design

Our approach to the software design involved the use of eight different tasks for the various moving elements of our gameplay. Seven of these tasks are dedicated to updating the matrix buffer of size 32x64 which is just a two-dimensional array holding the R2, G2, B2 and R1, G1, B1 values. The ninth task has the highest priority which is used to refresh the display. This task get the latest values from the matrix buffer and is used to display a frame of the game on the LED Matrix display. The matrix buffer is constantly updated in real-time by the other seven tasks such as:

  1. Title Screen:
    • Used to initially display the title screen
    • Waits for a button press to launch the game and then suspends itself
  2. Life Display:
    • Displays the health bar of the spaceship
    • When health runs out, suspends all other tasks and displays end screen (Game Over)
  3. Move Spaceship:
    • Used to display the spaceship at a location based on input from accelerometer
    • Collision detection between the Enemy ships and User Spaceship
    • On detection, changes the color of spaceship temporarily indicating damage
  4. Spaceship Bullet
    • Displays bullet on button press
    • Displays super-weapon on button press
    • Checks for collision between bullet and enemy bullet along with bullet with enemy ship
  5. Enemy Bullet
    • Displays enemy bullets
    • Checks for collision between bullet and enemy bullet along with bullet with user’s spaceship
  6. Kill Animation Task
    • Used to display explosions on collision between bullet and enemy
  7. Moving Enemy ship
    • Generates the enemies at random positions from the end of the screen
    • Moves the enemies in right to left direction towards the user
  8. Boss Enemy Task
    • Create a boss to fight every 12 seconds


The last task is the refresh display task mentioned above. This task includes a display function that controls the Latch, Clock, Output Enable pins of the LED Matrix display. This function reads the matrix buffer and extracts the R2, G2, B2, R1, G1, B1 values using shift operators.

Implementation

LED Driver

  1. Initialize all the pins and construct as output pins
  2. Create a matrix buffer of size 32x64 to hold the color values for the display
  3. Loop through matrix buffer from 0 to 31 rows and 0 to 63 columns
  4. Check if the R1,G1,B1 or R2,G2,B2 bits are set
  5. After every column the clock is set and then reset
  6. After every row the OE and LAT is set
  7. On clearing all the ABCDE bits, we extract each address bit and set the pin accordingly
  8. The LAT and OE is cleared, marking the completion of a row
  9. Refresh display task calls the display function and has highest priority
void display() {
  for (uint8_t row = 0; row < 32; row++) {
    for (uint8_t col = 0; col < 64; col++) {
      if (matrixbuff[row][col] & 0x1) {
        gpio__set(B1);
      } else {
        gpio__reset(B1);
      }
      if (matrixbuff[row][col] & 0x2) {
        gpio__set(G1);
      } else {
        gpio__reset(G1);
      }
      if (matrixbuff[row][col] & 0x4) {
        gpio__set(R1);
      } else {
        gpio__reset(R1);
      }
      if (matrixbuff[row][col] & 0x8) {
        gpio__set(B2);
      } else {
        gpio__reset(B2);
      }
      if (matrixbuff[row][col] & 0x10) {
        gpio__set(G2);
      } else {
        gpio__reset(G2);
      }
      if (matrixbuff[row][col] & 0x20) {
        gpio__set(R2);
      } else {
        gpio__reset(R2);
      }

      gpio__set(CLK);
      gpio__reset(CLK);
    }

    gpio__set(OE);
    gpio__set(LAT);

    gpio__reset(A);
    gpio__reset(B);
    gpio__reset(C);
    gpio__reset(D);
    gpio__reset(E);

    if (row & 0x1) {
      gpio__set(A);
    }

    if (row & 0x2) {
      gpio__set(B);
    }

    if (row & 0x4) {
      gpio__set(C);
    }

    if (row & 0x8) {
      gpio__set(D);
    }

    if (row & 0x10) {
      gpio__set(E);
    }

    gpio__reset(LAT);
    gpio__reset(OE);
  }
}

void refreshdisplay(void *p) {
  while (1) {
    display();
    vTaskDelay(2);
  }
}

Accelerometer Input

  1. I2C protocol to communicate with on-board accelometer
  2. Reading only the x-direction accelerometer data for spaceship movement
  3. Using simple math to calibrate the accelerometer data to corresponding position of the spaceship
  4. Comparing the accelaration data with its previous value to increase or decrease sensitivity
int getSpaceshipPos() {
  acc = acceleration__get_data();
  if (abs(acc.x - prev_acc) > 30) {               //Comparing the accelaration data with its previous value
    prev_acc = acc.x;
    if ((acc.x < 3400) && (acc.x > 2048)) {
      sp = 10;
    } else if ((acc.x >= 3400) && (acc.x <= 4096)) {
      sp = 10 + (acc.x - 3400) / 29;
    }
    if ((acc.x >= 0) && (acc.x <= 700)) {
      sp = 35 + (acc.x / 29);
    } else if ((acc.x > 700) && (acc.x < 2048)) {
      sp = 59;
    }
  }
  return sp;      //sp is spaceship position which will used in SpaceShip Task
}

Music Driver

  1. Aideepen Serial MP3 Player works when it receives specific bytes through UART protocol
  2. Depending upon the data and command bytes received from the micro controller, it will play file from SD card
  3. Supports .mp3 and .wav file formats.
  4. The MP3 chip undestands orders made of int array[8] with this format: (0x7E 0xFF 0x06 Command 0x00 Data1 Data2 0xEF)
  5. Format SD card as FAT32
  6. Add songs without creating any folder and name them as 001.mp3, 002.mp3 and so on
//For example, a couple of the macros used:
static int8_t Send_buf[8] = {0}; // The MP3 player undestands orders in a 8 int string
                                // 0X7E FF 06 command 00 00 00 EF;(if command =01 next song order)
#define NEXT_SONG 0X01
#define PREV_SONG 0X02
#define CMD_PLAY_W_INDEX 0X03 // DATA IS REQUIRED (number of song)
#define VOLUME_UP_ONE 0X04
#define VOLUME_DOWN_ONE 0X05
#define CMD_SET_VOLUME 0X06 // DATA IS REQUIRED (number of volume from 0 up to 30(0x1E))

//To send eight bytes to mp3 player using UART:
void sendCommand(int8_t command, int16_t dat) {
  Send_buf[0] = 0x7e;               // starting byte
  Send_buf[1] = 0xff;               // version
  Send_buf[2] = 0x06;               // the number of bytes of the command without starting byte and ending byte
  Send_buf[3] = command;            //
  Send_buf[4] = 0x00;               // 0x00 = no feedback, 0x01 = feedback
  Send_buf[5] = (int8_t)(dat >> 8); // datah
  Send_buf[6] = (int8_t)(dat);      // datal
  Send_buf[7] = 0xef;               // ending byte
  for (uint8_t i = 0; i < 8; i++)
    uart__polled_put(UART__3, Send_buf[i]);
}

Collision Detection

We used collision detection in a lot of places in our code. Bullet to Enemy/Spaceship/OtherBullet:

  1. Every time the bullet moves, we will check if the next pixel to the bullet is off (black) or not
  2. If the pixel is off (black), move on otherwise, check if the pixel is in the boundary of which object (enemy1/enemy2/UFO/BOSS/other bullets) then take action
  3. Same collision detection principle with Spaceship and Enemy, Spaceship and enemy bullet and so on

Here is an example where we used it for collision detection between enemy ship and bullet: (The part which can make a connection and get hit by the bullet)

//The if condition describes the detection between bullet and front boundary of the enemy spaceship:
if ((SpaceShipBullet_pos_x[i] == enemy_x && SpaceShipBullet_pos_y[i] <= enemy_y &&
         SpaceShipBullet_pos_y[i] >= enemy_y - 8) ||
        ((SpaceShipBullet_pos_x[i] == enemy_x + 1 || SpaceShipBullet_pos_x[i] == enemy_x - 1) &&
         (SpaceShipBullet_pos_y[i] <= enemy_y - 1 && SpaceShipBullet_pos_y[i] >= enemy_y - 7)) ||
        ((SpaceShipBullet_pos_x[i] == enemy_x + 2 || SpaceShipBullet_pos_x[i] == enemy_x - 2) &&
         (SpaceShipBullet_pos_y[i] <= enemy_y - 2 && SpaceShipBullet_pos_y[i] >= enemy_y - 4))) {

Testing & Technical Challenges

LED Matrix driver

Writing the LED Matrix driver was a challenge. We didn't get any material with the display. We had to search online and got a couple of websites explaining about the display. We also had help from the previous year's projects. After all the knowledge we could gain, we started writing the driver. We were successfully able to write the refresh display driver which uses a 32x64 matrix buffer that stores multiple 6-bit color data. The driver worked fine but there was one small issue. 32nd and 64th rows were much brighter than the others. After some testing, we figured out that we weren't clearing the last rows in each half of the display. After resolving that, our refresh display driver worked flawlessly.

Title Screen and Game Over Screen

When we tried to write the code for the title and game over screens, we wanted to make the design/font more eye-catching like most arcade-games are. However, coding each letter with the fancy font proved to be challenging and lengthy. Initially, we were having a function that would take the starting coordinate of where the letter should appear. To display the rest of the letter, we would have had to code the exact position of every pixel we wanted to turn on. This approach worked fine for small designs such as our spaceship, bullets, enemy ships and other minimal moving elements of the game. For gigantic letters with fancy fonts, we used a 2-Dimensional array of size 64x64, and input the values using Notepad++ and its handy column selection feature. Then it was just a matter of reading from this array to display the letters.

Soldering Issues

Initially, we couldn't get the LED matrix to work at all. The LED Matrix would just display random lines at a time. We did some testing and found out that ground pins on SJTwo Board were not soldered properly. A very simple issue but it got overlooked.

Conclusion

This project was completely successfully after a period of two months. Although we faced initial hiccups due to a lack of datasheets for the LED Matrix, the project went smoothly afterwards. Working on this project has given us so much confidence in using the FreeRTOS API and sharpened our embedded software skills. We also followed a strict schedule which helped us deliver the project on time and improved our time management skills. Working in a team of 3 has also boosted our teamwork skills.
