- DSP56001 TNC
- by Jarkko Vuori, s30874w@kaira.hut.fi
-
- This program is a beta version of the DSP TNC for the DSP CARD 3 signal
- processor card. It implements the full (Bell 202) TNC with KISS interface.
-
- This program is intended for private use only. You may redistribute far
- and wide but charge no money, not even handling fees.
-
- Commercial use of this code is absolutely prohibited without permission of
- the author. This code may not be used as the basis of any program that will
- be sold, bartered, or in any way traded for gain without the permission of
- the author.
-
- There is no warranty. What you see is what you get.

- EQUIPMENT REQUIREMENTS
-
- The code is written for Motorola DSP56001 digital signal processor, and it
- needs:
- * X memory: 0000H - 00FFH (approx.)
- Y memory: 0000H - 00FFH ( -"- )
- P memory: 0000H - 0FFFH ( -"- )
- * SCI port connected to the host computer (by KISS-protocol)
- * Texas TLC32044 converter chip (master clock 5.184 MHz) connected to
- the SSI port
- * SC1 connected to the PTT
-
- To compile the source code you need Motorola ASM56000 cross compiler and
- LNK56000 linker and Microsoft Make (or compatible) utility.

- OTHER INFO
-
- The code implements DSP KISS-TNC. It uses a special multibit observation in
- demodulation, and integrated symbol syncro so its Eb/No ratio is about two dBs
- lower than the plain vanilla TNC. It is altought very dependent on the exact
- Bell 202 frequencies, so it can't be used on SSB links.
