Volume settings permanently

by Mosselpiet on Wed May 19, 2021 7:17 am

Hi,

I am using the AdaFruit Sound Board.

Manual:
Volume Trigger pins
These are two extra inputs that can be used to adjust the volume in GPIO trigger mode only. Connect
buttons that go from each pin to ground, when the button is pressed, the volume will decrease or increase
The volume is not stored during power cycling or resets, so it will have to be re-applied after restarts.
download


Question:
Is it possible to store the volume ?

hope someone can help.

@Mosselpiet,

I can see how volume not being stored would be frustrating.

The only two options I see are:

1) You can attach buttons connected to vol+/vol- with a connection to GND to manually toggle the volume when power is lost.

2) You can leave a microcontroller connect on the serial uart that inserts the correct number '+' to increase the volume to your default mode. It would be nice if you could just send the desired volume level over via uart, but no.
