Crude GUI for testing GPIO pins on Orange Pi 5
Toggle on and off GPIO pins on the Orange Pi 5 by clilcking on buttons in a window on the screen. This program uses the wiringOP and GTK libraries, download and install per the the instructions on the websites:
https://github.com/orangepi-xunlong/wiringOP
https://www.gtk.org/docs/installations/linux
To change GPIO pins you only need to edit the "define" section of the program. Change the number after each of the GPIO_PIN_A, B, etc to select which pins you want to toggle, and edit the buttons to read whatever makes sense to you.
To compile, from a terminal in the same directory as this file enter -
gcc $( pkg-config --cflags gtk4 ) -o GUItest2 GUItest2.c $( pkg-config --libs gtk4 ) -lwiringPi
to run, from a terminal enter -
sudo ./GUItest2
to confirm GPIO state, from a separate terminal enter -
gpio readall
