mTouch without cap sense module? confused on peripheral requirements
I have a Curiosity DM164137 board with PIC16F1619. The board has a sense pad that I've gotten working as both button and proximity sensor using mTouch installed through MCC in MPLAB X IDE v4.20.
The thing is, I can't find anything in the PIC16F1619 datasheet referring to mTouch (except for a trademark notice) or cap sense / CPS. On the other hand, the PIC16F1824 datasheet, another chip I've used mTouch on before, lists 8 capsense channels in the datasheet, mentions mTouch in the overview, and includes a chapter on CPS usage.
So what's going on with the 1619? How is it even working? Does the mTouch library bitbang ADC channels to fake it if the chip doesn't have CPS?
