Other Parts Discussed in Thread: CC2640

Hi,

We have designed a capacitive touch pad for cc2640 . The PCB image is attached below.

Totally we have 16 touch pads.

what we want is Whenever we touch these pads ,there should be variation in capacitance and that should be sensed. Will this design work for this module.

Hello Rohit,

You can connect any electrically compliant accessory to the CC2640; refer to the data sheet & TRM for more details on the IO capabilities.

Beyond that, how do you intend to do the capacitive processing in your driver?

Best wishes

Hi @rohit total,

You have designed the PCB for CC2640 but don't know if it can work? You should know how to make the circuit work before the PCB, right? So, how about the circuit of this PCB?

Hi robert,

We are being new to this design module, and we are not been explored with interfacing of capacitive touch controllers and it's interfacing with the CC2640..
