Detailed Description

Configuration settings for Raspberry Pi zero.

This file contains some platform (type) specific definitions. These settings influence the compilation and build process. Most of those settings can not be changed later at runtime.

With respect to (process) I/O pins there is no difference to Pi3 and Pi4.

Macro Definition Documentation

stdUARTpath

#define stdUARTpath

/def stdUARTpath Pi's standard UART.

It is the one on the Pins 8 (GPIO14) for Tx and 10 (GPIO15) for Rx. Here it is set to the long year standard value /dev/serial0. As this seemed changed in some Raspbians, this macro definition can be overruled in a target specific include file.
