Firebeetle esp32

[KennyM64]

Hi, I like the concept but it doesn't seem to work with boards that have dedicated Analog ports. I'm using a Firebeetle ESP32 for IoT as it has 5 dedicated analog ports 15, 34, 35, 36, and 39. However only 15 works in a simple sketch with the others throwing a "E (282666) ledc: ledc_channel_config(608): gpio_num argument is invalid" error.

Anyway around this?

https://wiki.dfrobot.com/FireBeetle_ESP32_IOT_Microcontroller(V3.0)__Supports_Wi-Fi_&_Bluetooth__SKU__DFR0478 analogWrite(15, 256); delay(1000); analogWrite(35, 512); delay(1000); analogWrite(34, 1024); delay(1000); // wait for a second analogWrite(39, 256); delay(1000); analogWrite(36, 512); delay(1000); analogWrite(15, 1024);

if you remove the GPIOViewer Library and run the code above, do you get the error message ? What ESP32 Core version is reported by the GPIOViewer on the serial monitor ? because pin 34-39 are input only, you cannot write to them

Apologies. It seems to be an issue with the board and how it's assigning dedicated Analog ports to the Firebeetle ESP32. A0-A4 use GPIO's 36,39,34,35,15. If I change the board to an ESP32 Dev Kit I get the same errors. Looking at the pinout https://mischianti.org/wp-content/uploads/2020/11/ESP32-DOIT-DEV-KIT-v1-pinout-mischianti.pngfor the ESP32 Dev Kit it shows 36,39,34,35 as input only. So I presume this carried over to the Firebeetle board but isn't documented https://raw.githubusercontent.com/Frances9/DFR0478/master/DFR0478%E5%BC%95%E8%84%9A%E5%9B%BE01.pngas such.

All good :-) Well done on the code it will be very helpful. I'll keep an eye out for new boards.

Thanks, glad it is not working.
