I am using the MPR121 chip to control 8 capacitive buttons. If I press any one of these buttons while the initialization is in progress, the chip no longer responds to interaction.
If I ensure nothing is in contact with the touch buttons during initialization, all of the buttons work properly. I have tested this on 16 units, and all of them react the same.
I followed the source code outline on Sparkfun's website for my initialization procedure. I also looked through the available application documents provided, but did not see anything relating to this issue. Has anyone else encountered this problem and if so, was a solution found?
Thank you in advance for any help provided.
