A serial terminal program for the atari 8-bits (I am using an Atari 400) to suit my needs for amateur radio.
This is written in C to be compiled with the awesome cc65 compiler.
(Because this is still a work-in-progress)
- Basic CIO routines
- High-level keyboard input routines
- Custom display list & DLI, VBI interrupts
- Scrollable text buffer
- High-level display routines
- High-level Atari 850 routines
- Configuration & Config help
- Saving/loading config to/from disk
- Atari 850 connection ui
- Buffer logging
- UTC clock
- RTC extension?
- High-level TNC communication & interface?
- APRS functionality?
- RS232 GPS interface?
- Arduino-based PSK interface?
See Theory of Operation.
There are many terminal programs for the atari that are great, but here is what I want to implement here (we'll see what I get to):
- UTC Clock in the corner of the screen
- Customizable ATASCII -> ASCII mapping
- Customizable RS232 settings (All 850 interface module settings, but in a menu!)
- Saving a log to a file, cassette, or printer
- Other settings, like disabling keyboard beep or having it beep on tx
- Multi-page scrollable buffer
- Customizable buffer-flushing (flush after each character, after each line)
APRS Mode:
-
APRS packet parsing (maybe using serial-connected GPS also?)
-
APRS packet plotting on a map
-
APRS packet logging to a file or printer & plotting any log on map
-
APRS digipeater?
After seeing this blog post by KO7M, I thought it would be cool to make an Atari PSK interface based around an Arduino (my MFJ TNC doesn't do PSK by default).
To run compile.sh, you need:
- bash
- atari-tools
- wget
- atasm
The compile.sh script should be run from the root of the repo,
and will download a dos image from online (not mine), assemble hamterm, and add it to the image.
In the end, you will be left with a bootable atr image hamterm.atr.
It is much faster to use the atasm-altirra bridge VSCode extension for development-- the Altirra debugger is very helpful.
It took a while for me to figure some of these things out (that may be my being fairly new to 6502 assembly...), so I would be thrilled if it was somehow helpful to anyone else. Please include the license / copyright notice if you do use any "substantial portion", as per the MIT License.
But there are examples of VBI/DLI stuff, Atari CIO calls, and some ATASM/M65 utility macros:
- 16-bit increment/decrement
- 16-bit minus 8-bit subtraction
- 16-bit plus 8-bit addition
I would be thrilled if any of this was helpful to someone else!
I learned a lot during this project (and as of this writing I've still a long way to go on it...), and that wouldn't have been possible in the same capacity and efficiency if not for these amazing sites:
