Detailed Description

Configuration settings for Raspberry Pi1 (Models A).

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.

Since end 2017 we mostly use Pi3 and Pi4.

Macro Definition Documentation

GPIO2pin

#define GPIO2pin

GPIO [0..39] to pin number (1..40) lookup list.

0 means has no pin on the 40 pin connector

See also

PIN2gpio gpio2pin

PIN2gpio

#define PIN2gpio

Pin number [0..26] to GPIO number lookup list.

Return values:

0..56: "real" GPIO number;
95:     5V pins;
93: 3.3V;
90: Ground 0V;
99: not existent 

N.b.: [1..26] are: valid pin numbers, only.

GPIO2pin pin2gpio

stdUARTpath

#define 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 to be changed in some Raspbians, this macro definition can be overruled in a target specific include file.
