CC2650 capacitive sensing feature

terry chang

Hi,

I try to using capacitive sensing feature to make a button can wake up power to active.

I try to do this with Sensor Controller Studio, but it look like another trouble to understand and integrate to ble app.

So I use CC26XX driver [auxtdc] AUX Time to Digital Converter API. But...

Is any example can show me how to use CC26XX driver [auxtdc] AUX Time to Digital Converter

to do a capacitive sensing button maybe with wake up feature.

Thanks,

Regards,

Hello Terry,
Currently we only have the Capacative Touch Data Logger example code. But you can rewrite that and for example use the system CPU alert to wake up the System CPU when you detect a button push. The current example simply pass the TDC values and wake up the system CPU when it calls fwSwitchOutputBuffer.
