Unable to enable I2S 3W Class D Amplifier Breakout with Left Shoulder button. #76
Description
I was trying to install the image provided by the repo but seems that is too old for my current setup. Then I tried to replicate the steps for everything to work as expected (buttons, I2S audio, etc) and it worked well until I try to enable the I2S Audio board.
For what I read, it seems that the I2S is using GPIO pins 18,19,20,21 even if the amp board is only using GPIO 18,19,21. The PIN 20 is for the Left Shoulder button, so you can have only one thing enable at a time, the button or the audio. Unless that the original image has some custom Device Tree Overlay for the Amp board that I'm not seeing. Because I was unable to install it, I can't look for those files.
Anyone have any idea how to solve this?
