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
- Open in 3D viewer
- Clock: 1000 Hz
How it works
UARTS and two conversion ROMs
How to test
Serial data in and see how it goes.
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.
IO
| # | 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 | segment d | |
| 4 | segment e | |
| 5 | segment f | |
| 6 | segment g | |
