We are go!! I’ve got the plasma 2040 up and running and systems are firing on all cylinders.
My next step is attaching more buttons - at least 12. Can anyone recommend the best QW/ST module to attach more switches to a Plasma2040? Or if a QW/ST is not right, then another way of getting 12 buttons on here?
You should be able to use the SDA, SCL, INT pins as GPIO for buttons. As well as A0, A1, A2 and maybe the SWC ,SWD?
Then add button combo’s, If 1 and 2 pressed do this
I am going to try a multiplexer which has 16 channels ⭐️ I’ll let you know how it goes
If anyone from the future is reading this, I have not yet tested this, but I believe the easiest thing is the IOexpander, made by Pimoroni themselves.
It will be a week or so before I check this out, I will update this thread.
