B-Man · April 18, 2018 at 4:12 AM

i read somewhere i had to add some code to the config.txt

but the way i read it is for IR remotes etc and its just 1 pin?

i want to use 4 gpio pins what do i have to do?

i have installed the raspberry pi tools from the repository

From: Wiki

Add the following line to /flash/config.txt (read Raspberry Pi Config.txt for detailed instructions):

Code

dtoverlay=gpio-ir

Add the gpio_pin parameter if you used a custom GPIO (default is 18). eg:

Code

dtoverlay=gpio-ir,gpio_pin=5
