Detailed Description

A very first program for Raspberry's GPIO pins 75 (19.02.2025) Copyright (c) 2024 Albrecht Weinert weinert-automation.de a-weinert.de.

This is a most simple version of a GPIO pin output program using pigpio(d).

Compile on Pi by: g++ gnBlinkSimple.c -o gnBlinkSimple -lpigpiod_if2

Compile on Windows by: arm-linux-gnueabihf-gcc -I./include -c -o gnBlinkSimple.o gnBlinkSimple.c arm-linux-gnueabihf-gcc -I. gnBlinkSimple.o –output gnBlinkSimple.elf -lpigpiod_if2 -lpthread cp gnBlinkSimple.elf gnBlinkSimple winscp.com /script=progTransWin /parameter sweet:0123 targetPi bin gnBlinkSimple

Variable Documentation

thePi

int thePi

The standard Pi for gpio(d) IO of the program.

This global variable is provided to hold the main pi used by a program doing process IO via piGpIO[d]. In most local use cases

thePi = pigpio_start(NULL, NULL); 

it will be 0 = this local Pi. After usage don't forget to terminate the connection to the pigpio daemon by

pigpio_stop(thePi);
