I am looking to see if anyone has the code to make your own 4, 5, or even 8 functions, and can be used with DIGITRAX systems. I am a retired electronics engineer, and I am looking to make my own decoders, as I can do the hardware, VERY easily, and make bords really cheap. I'm just NOT a programmer, at 64, I keep working at it, but, it is taking forever, and I would like to make them before i expire!!! lol!!!! Thanks everyone for reading, and responding!!!!
