renegade labs ground board wiring.

[reto]

hello a while ago i bought this " https://kydoraelectronics.com/product/g ... ted-audio/ " and i am finally trying to finish my build but i am a little confused on how to wire it up except for the buttons. i am using the raspberry pi zero gpio pins for audio and controls. i checked the website and tried to contact the manufacturer but i couldn't get any help. a diagram would also be helpful. i also have issue on how to configure retropie to use the gpio for both controls and audio. is there a guide or a prebuilt image i can use?

You'll have no luck contacting renegade labs likely.

I'm not too familiar with the products, but have not heard anything good about customer service.

You can inspect the traces for each button, and find which gpio they go to pretty easily. And use that info and install retrogame (check adafruits guide).

As for audio, if it's just using PWM it will use gpio 18 or 13 (or both). Again looks at the traces from the audio lortion and see which gpio pins the go to.



Got any pics of the board?

For audio, all you need to do is add this line to the config.txt
(If using both gpio)
dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4

(If using one gpio - 13 or 18)
dtoverlay=pwm,pin=18,func=2
