116 Baudot Converter
116 : Baudot Converter
- Author: Arthur Hazleden
- Description: This circuit will convert ASCII serial data to baudot serial data provide the reverse funtion as well
- GitHub repository
- Most recent GDS build
- HDL project
- Extra docs
- Clock: 1000 Hz
- External hardware: The ASCII is expected to come in/out from a USB-serial adapter. The baudot is a 60mA current loop so something hefty is required.
How it works
UARTS and two conversion ROMs
How to test
Serial data in and see how it goes.
