PCBs for the excellent FPGA synth projects XFM2 and XVA1.

Custom 6502 Video Game Console

SPI slave to External SRAM interface for Cmod A7

6502 Arcade Machine by UCSB IEEE

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

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.

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

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

A reusable and configurable template for FPGA development projects using Verilog and Xilinx Vivado. This template is designed for the CMOD A7 FPGA board but can be easily adapted for other boards.

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

A simple breakout board for the Digilent 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.
