SPI slave to External SRAM interface for Cmod A7

6502 Arcade Machine by UCSB IEEE

Xilinx Artix-7 FPGA design using block ram, XADC and a SPI slave (SCARF). The block ram is dual port and can be written by either SPI or XADC samples, and only read by SPI.

SystemVerilog FPGA design of a custom trigger circuit which can be used with oscilloscopes or logic analyzers.

FPGA design to allow for programmable delay on a single signal. Implemented and tested on CMOD_A7

This is a demonstration of UART communication using the FT2232 on the Cmod-a7 FPGA board. The TX and RX are passed through the FPGA to board pins, which then connect to my Raspberry Pi. Bi-directional communication is demonstrated in Python.

The FT2232H on the CMOD-A7 is used to drive UART data to read/write to a register map implemented in block ram.

A simple breakout board for the Digilent CMOD A7

Xc3sprog compiled for Raspberry Pi with support for Numonyx (Micron) N25Q 0x16 memory which is on the Cmod-A7 FPGA board.
