Qtouch on Microchip
« on: April 13, 2020, 08:34:14 pm »
Hi,
now that microchip has acquired Atmel, are there any Microchip micros that use any of the Microship "classic architecture" (8, 16 or 32 bits) which also have Qtouch?
I want to implement touch controls but want to stick to the Microchip micros and I don't particularly want to use external Qtouch ICs.
Any suggestions?
Thank you :)

Microchip PICs usually have 2 types of hardware for capacitive sensing: CVD and CTMU. They're older than Microchip's Atmel aquisition, so not the same technology. I'm unaware of any later PIC with a different hardware for touch sensing.

Thank you Dmendesf,
from memory they need a metal plate and they measure the microscopic displacement of the metal plate (inductive and/or capacitive) is that correct?
Thank you :)

No, they can also measure self capacitance and mutual capacitance as qTouch. Just maybe without the same fancy tools to trim the results.
