Max Stopyra and I implemented an Etch-A-Sketch using an FPGA and a capacitive touch screen. Using SystemVerilog, I created a finite state machine
representing the states and transitions of the Etch-A-Sketch. The two controllers to communicate with the capacitive touch screen and the display controller
respectively use I2C and SPI. A more in-depth description can be found in my
lab documentation, and the code implementation can be found in my
GitHub.
