Hi guys
I don’t advise anybody , especially beginners , to change the code for their needs!
Of course this is Open Source and you are free to do it, but I will not follow you on that!
The only thing to do , to adjust the code to your HW configuration, is to modify pins.h file where all the modifiable code flags (#define) are located.
To do that :choose one of the 11 proto cases, the one better for your needs and modify the value of the #define there.
Minimum HW configuration is proto 11!
