INTRODUCTION

We intend to design a game using RGB LED Matrix and microcontroller LPC 4058.

ABSTRACT

The idea is to relive the childhood days using this game with the characters as Tom and Jerry. Jerry will run inside the maze which will be displayed on the RGB matrix. The route for the mouse will be selected from the pre-defined path at initial state in runtime. Tom (player) will chase this mouse by tilting the board left and right. We are using the SoC accelerometer in SJ2 board for sensing the motion. The cat must catch the mouse before mouse reaches its destination hole. If cat get attracted to drink milk (this is an obstacle), then it must halt for some time, and this will waste it’s time for a while at the same place. The mouse will start running first and then after a delay, the cat will start its motion. The score will be displayed on the LCD which is optional display.

OBJECTIVE

The game objectives are as follows:

    • Interfacing the RGB LED Matrix with SJTwo Microcontroller
    • Coding simple to use display functions for displaying characters at any given position
    • Randomizer to generate random position for Jerry
    • Tasks that can move Tom depending on the user:
    • Interrupt to be generated on press of button to start game/Pause the game
    • Score Counter and Energy Counter to be displayed at the top and updated in real time as the game progresses
    • Title Screen and Game Over screens
    • MP3 driver for playing audio

PCB DESIGN

We have designed and developed a PCB in order to supply power for SJTwo board and RGB LED Matrix which is able to provide 5V supply efficiently. The PCB Layout is designed using the Easy EDA Online Software Tool. The Power Supply circuit board used contains IC7805 voltage regulator IC and a voltage divider to fulfill the specific power requirements. IC7805 is a linear voltage regulator which has a variable output voltage ranging from 4.8 V to 5.2 V and is suitable for our application. We have used a 5V adapter in order to power our board. This serves for both the current requirements.

Fabrication

PCB was sent to fabrication to JLCPCB China which provided PCB with MOQ 2 layers of PCB. DRC elements (in mils)

  • Track Width = 12
  • Clearance = 10
  • Via Diameter = 24
  • Via Drill Diameter = 12

INTEGRATION AND TESTING

TECHNICAL CHALLENGES

LED Matrix

The OE pin when low, it switches off the LEDs before transition to next row) and LAT (when high) it latches the output pin with current row value). Before transitioning new row value it is important to follow the above instructions, otherwise you will see ghosting effect in the LEDs.

PCB

  • Auto-routing gave lot of challenges and sometimes the wires are barely connected which throws DRC errors very frequently. Even local routing had lot of issues. So design requires careful attention and time.
  • The PCB went through a lot of internal revisions even before placing order which was time-consuming.
