UART interface to a block ram in the Tang Nano 9k FPGA. No pin connections needed, just use the USB UART.

HDMI for Tang Nano 9K

A small and cheap triggering system for side channel attacks using Gowin FPGA

This is a re-write of my previous trigger project. This time Tang Nano 9k is the target hardware and the USB UART is used to configure and enable triggering.
