Posted at 2020-04-12 by @MaBecker Thanks for sharing, that's what I had in mind when I saw how you place the black circles. Any information about the power consumption? |

Posted at 2020-04-14 by SiFu According to the datasheet of the CAP1188 chip: "50uA quiescent current in Standby (1 sensor input monitored)". I will investigate more, if i find that the battery drains too fast. |

Yes, a setWatch() on an interrupt pin would be much more effective. Did you had to create spirals at the cable ends or something similar, to make it more sensitivity? |

As this is a nRf52, Just stumbled across this using Low Level PPI:

Posted at 2020-04-14 by SiFu @mabe: No, the default sensitivity was too high with the way I originally had my wires. So I had to shorten some wires and bend others to have them apart as much as the limited space allows. @robin: oh, nice! might try this one day. Would be curious if I could get that to work more reliable than the ESP32 touch pins I tried initially. |

Hi there! :)
I recently bought some MDBT42 breakout boards and love them :)
Now I hooked up a Adafruit CAP1188 touch board to one of them and it works (with the https://www.espruino.com/CAP1188 module), but I would need to change the sensitivity of the board and I have no clue how to do that.
In Arduino this would work:
uint8_t reg = cap.readRegister( 0x1f ) & 0x0f;
cap.writeRegister( 0x1f, reg | 0x6F );
Can anyone point me to the right direction?
Thanks,
SiFu
