  Hello!

  Does anybody with ESP32 experience know if there is a way to use the capacitive touch GPIOs of the ESP32 with Espruino?

  Thanks!
  Ronald

  Thanks for your reply. I just added an issue for this: https://github.com/espruino/Espruino/issues/1574

  Hello Patreon,

  Thanks for your response. The analogWrite appears to work on a non DAC pin, like GPIO5. On a DAC pin, like GPIO26 it will only turn off the LED. It's a bit confusing.

  Maybe it will work in a next version, I am OK with this outcome.

  Yeah... I know how google works.

  Thanks for helping me think this trough and for pointing me to some remarks in the documentation. I will dive into this.

  In the mean time can who knows how to get DAC or PWM working on an ESP32 please elaborate a bit?

  This is the board: http://wiki.widora.cn/_media/air-spec.pdf

  It exposes all the ESP32 pins, and also GPIO26.

  Did you see analogWrite working on any ESP32? What would you recommend for the third argument?

  No worries, no LED are being killed here. :-)

  I just trying to dim an LED in the console of the the Espruino Web IDE. For what I understand GPIO26 supports DAC. https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/dac.html, correct?

  I just did the same on GPIO4 (a PWM output) of an ESP8266 which works as expected.

  I just try to control the brightness of an LED, similar to this: https://www.arduino.cc/en/Tutorial/Fading, just basic stuff. I did not set the pinMode, because analogWrite will set it to 'output'.

  Oh... with LED dims I mean it turns black. And, even more surprising, after that it does not light up anymore with digitalWrite(D26, true)...
