New Hardware
For this project, we covered some new hardware not previously used in this classs. On the FPGA side, we had not previously driven an LED matrix display. We also used SPRAM in our implementation of the display buffer, which was not previously covered on in the class. For the MCU, we made use of the onboard I2C Peripheral on our STM32 MCU, using it to interact with an IMU.
Schematics
Below is the KiCad schematic of what we eventually implemented on our Perfboard.
