GPIOS CONFIGURATIONS AND USERSPACE RGB LED CONTROL

Tue Sep 03, 2019 12:10 am

Hello.

I have SAMA5D27-SOM1-EK1 board and i want to customize it for personal use. I am using Linux environement.

I want to learn more about GPIOS mapping and configurations in order to take control of the peripherals existing on the board. For that, I think I need to start with a simple example to better understand.

What I want to do now is to take control of the RGB LED. The Blue one is Heartbeating when the Linux OS of the board is running. For exemple, I want to make it lights ON and OFF and take control of it from USERSPACE. I do not want to use shell commands.

Any suggestions of how to do that ?
