if you want to use v1.6 with your hardware, you’ll need to tell the firmware what it’s connecting to. you do this in io.h. at the top, there are a series of #define statements. un-comment the two that belong to your input & output cards, and comment out the rest. when you build the firmware it will ignore the code for the other io cards (e.g. the the input card with the 31855 chip,) and will keep the code that pertains to your cards.
