Reply to "Python code to issue TMCC, Legacy, and PDI Commands"

cdswindellOGR Forum Member SUPPORTING MEMBER

I've started reading data from the Lionel Ser2. I can now interpret all of the TMCC1 commands and have unit tests in place verifying that I can construct a command, send it, and recover the exact same command (and address/data) from the transmitted bits. Decoding the 3 byte TMCC2 commands should be straightforward.

Interestingly, the SER2 strips away any of the PDI prefix and suffix bytes. I don't know if this means I can only read TMCC/legacy commands from the SER2 (and not read commands coming from the other LCS devices). I have to do some more experiments.

I just ordered a Raspberry Pi Zero with WiFi to test my code on. These little boards are only $15 and support WiFi. If they have the memory and horsepower to run my stuff, they would be the perfect chip to put into a control panel.
