I was experimenting with the MPR121 for proximity, and have managed to get a basic demo up and running. I am getting the distance as 2-3 cm, is there anyway we can increase the distance?
Some suggestions with the register values might help, as well as suggestions for electrode material ? I am currently using aluminium foil as a test.
The current configuration of the registers I am using is :
// prox sensing rising
// prox sensing falling
// Section D - Set the touch filter Configuration
I have disabled auto config and auto reconfig, but here were the original settings
