Qtouch auto-repeat implementation
« on: May 10, 2020, 02:22:47 pm »
Hi all,
has anybody implemented autorepeat for a QTouch sensor/ketpad?

I am planning to use this IC ( http://ww1.microchip.com/downloads/en/DeviceDoc/doc9634.pdf ) but it does not mention anything about autorepeat or detecting if the user keeps the finger on the QTouch pad.

Any ideas or alternatives?

Many thanks :)

thank you.

Any other suggestions anybody? That IC does not seem easy to be sourced from the major European/US distributors.
