Driver for the Analog Devices' EZKIT Lite DSP board.
This driver allows Analog Devices' EZKIT Lite DSP board to be used as
a two channel packet radio modem. Each channel can be used either with
1200 baud AFSK or 9600 baud FSK compatible to G3RUH.
Currently there are 4 EPROM files:
| Filename |
Left Channel |
Right Channel |
| TNC1212.EXE |
1200 Baud |
1200 Baud |
| TNC1296.EXE |
1200 Baud |
9600 Baud |
| TNC9612.EXE |
9600 Baud |
1200 Baud |
| TNC9696.EXE |
9600 Baud |
9600 Baud |
WARNING: These files do not contain PC executable code!
Calling them will cause the PC to crash. However, these files can be processed
with Analog Devices' tools, such as the PROM splitter and the loader.
The driver reserves two channels. The baudrate of the channels must
be configured according to the EPROM!
