Hello,

Can I use SAMD21 Touch features without a panel? The PCB itself would be the panel. I would use mutual touch flooded-x method.

And: I plan on using i2c driven RGB LEDs, WS2811, on a separate PCB (below the PCB with the sensors) for back lighting. How far away should these be from the x-sensor?

 

Sorry if this might be a double topic – I searched this forum and the web but did not find anything conclusive.

 

Thanks

Refer to the relevant manual:

Atmel-42119-SAM-D20-D21-System-Clock-Management-Driver-SYSTEM-CLOCK_Application-Note_AT03259

You can set this up, try it.
