// RasPi.h
|
||||
//(9/22/2019) Contributed by Brody M. This file is based off RHutil\RasPi.h
|
||||
// but modified for the pigpio library instead of BCM2835. Original
|
||||
// code maintained where possible. Unused code commented out and
|
||||
// left in place. WiringPinMode enumeration declaration borrowed from
|
||||
// STM32ArduinoCompat\wirish.h. Also some enumeration declarations
|
||||
// "borrowed" from bcm2835.h to maintain original code and for simplicity.
