Soccer Pong

Project Title

SOCCER PONG

Abstract

At the time this project was created (fall 2022), the soccer world cup was taking place. Having caught a little of the world cup fever, Soccer Pong looks to combine the gameplay from soccer and the original Pong. Two games from different mediums but with great symmetry. Two players will face each trying to avoid being scored on. A ball will bounce from any surface that is not in the penalty area. Once a player has read the set maximum number of goals, a victor will be crowned. Press the reset button and let’s go again!!! Soccer Pong brings a new flavor to a historic game, taking you into the world of soccer.

Objectives & Introduction

The main objecive of this game was to create a simple pong game and then change it to something more unique. The following were the objectives we had to reach our goal.

  • Create a Matrix Driver to display all of the visuals of the game.
  • Implement ADC joysticks controllers Driver to handle the players blocks movement
  • Implement Reset and Pause buttons using semaphores interrupts to reset the game and pause the ball movement
  • Incorporate music and special effects by adding a mp3 modules with UART interface.
  • Design a PCB that will combine all of the peripherals dfevics with the sj2 board and matrix.
  • Create a task that will refresh the matrix driver buffer with the ball and player movement.
  • Develop control system with the ability to modify speed and size of blocks
  • Create task that will handle ball movement, placement, and hit detection.
  • Incorporate the music and sound effects after specific time based events (hitting block, goal, etc).
  • Integrate the pause and reset buttons

      Hardware Interface

      Circuit Block Diagram


      In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

      Software Design

      Gameplay Flowchart

      Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.


      Led Matrix

      Hardware Implementation and Design

      All the pins were set up to be close to each other for better readability. The led matrix required 16 pins as specified above with two being ground. It required 5v with at least 2.1A current. The led matrix uses daisy chaing shift registers to set up the rows. The RGB1 pins set up the color of the top half leds and the RGB2 pins set up the color of the lower half leds. To control the lower half leds both RGB1 and RGB2 need to be set simultaneously. The matrix is 64x64, but works more like a 32x64 matrix. Pins A through E will select the row of the top half. For example, pixel 32x1, will light up when pixel 1x1 is on. This means that both RGB1 and RGB2 need to be set or reset simultaneously. For one pixel to be set, all other pixels need to be reset.


      Software Implementation and Design

      We used premade 64x64 arrays with the background and smaller arrays for game objects. The code will check which pixel needs to be light up if its 64x64 matrix if will line up both leds. If its a specific object that its only on one side, it will light up the pixel and set the other pixel 32 rows away to off. For one pixel to be on all pixels need to be set up. This means that one will be on and 63 will be off. The result is saved to the array buffer. This buffer is updated everytime a new pixel is added. A draw board function is set to always refresh the background before adding new pixels. This is done to not have trails of the balls and blocks movement. This means that every pixel is reset in the led task. Uses the led driver to set up full objects this way they all move in unison instead of just changing one pixel at a time. The led has the lowest delay in order to have less static and for the graphics to remain crisp.


      void led_driver__refill_refresh(uint8_t (*update_matrix)[64]) {
       for (int row = 0; row < 64; row++) {
         for (int col = 0; col < 64; col++) {
           led_matrix_refresh_array[row][col] = update_matrix[row][col];
         }
       }
      }
      
      static void fill_word(uint8_t y, uint8_t x, uint8_t array_x, uint8_t array_y, uint8_t insert_word[array_y][array_x],
                           color_code color) {
       for (int row = 0; row < array_y; row++) {
         for (int col = 0; col < array_x; col++) {
           if (insert_word[row][col] == 1) {
             led_driver__setPixel(row + y, col + x, color);
           } else {
             led_driver__setPixel(row + y, col + x, insert_word[row][col]);
           }
         }
       }
      }
      

      Implementation

      This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

      Testing & Technical Challenges

      Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

      Include sub-sections that list out a problem and solution, such as:

      <Bug/issue name>

      Bugs

      • Joystick input had a fixed paddle speed
      • Pause and Reset buttons service with ISR was difficult to debounce, moving button input detection to a Task would be more practical

      Conclusion

      Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
