Week 10

Add an output device to a microcontroller board you've designed, and program it to do something

I tried to make a tiny game console this week.

I started by the helloworld example from HTMMA website.

The circuit on breadboard for testing.

Circuit design.

PCB board design.

When I was tilting the board it was ripped off by me from the PCBboard.

A working version on breadboard.

I found this code online, this was using the arduino uno chip. I then looked for the corresponding pins for I2C connections in XIAO RP2040.

The code was not working, and I had to modify a few parts.

I realized that this might be too fast to play.

I modified the code to make the speed way slower, and snake size larger.

Had Tetris working horizontally, but not vertically. Turned out there's no easy fix besides rewriting the code.
