“Buttoning” up the prototype
UPDATE: There are some major errors in all 3 PCB designs that were found after testing so I would not use them. I removed the links to help remove temptation.
After getting the potentiometers to work as expected I was …
So many broken things but now fixed.
It has been quite a while since the last post and the reason is that I just could not get two chips working on the same SPI bus until now. I had the basics right but a few different things …
And the numbers go up and down, or testing a voltage divider.
