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.


# Input Output
0 ascii clock at 8x desired baudrate segment a
1 baudot clock at 100x desired baudrate segment b
2 baudot input, should be held high when line is idle but connected segment c
3 none segment d
4 none segment e
5 none segment f
6 none segment g
7 none none
