ADC-2 does not work when WiFi is enabled....

ESP-WROOM-32 modules with 8 MB and 16 MB Flash are now available (as well as ESP32-Wrover modules ), so there is not much need for adding the external flash chip. Very cool! Ive been waiting for someone to make custom WROOM32 with 16MB of flash, that is also FCC certified with the metal RF shield. ...

Why not use ledcWrite?

I have encountered this once before...using Arduino, the SSID and password seemed to be "permanently" burned in and would not change by uploading a new sketch. Try doing a complete force-erase manually using esptool.py. Then reflash your program using the Arduino IDE. That should clear any existing ...

Every once in a while I too get that random MD5 error when reflashing the ESP32. Cycling power always fixes the problem though...

Curious if anyone else has any updates on getting CPU utilization working in % using Arduino?

I'd like to print each core's CPU utilization in "xx%" in a serial terminal window...

thanks

Doh!!!! Stupid me, I totally forgot to include that header file.

Many thanks again for the help...seems to work perfectly now.

It wouldn’t compile without esp_err_t in there...said “rtc_deinit... not declared in this scope”

Hi everyone, had a quick question regarding deep sleep using a hardware interrupt for wakeup. My project is using CAN bus with CAN Rx on GPIO-4, and CAN Tx on GPIO-5. The goal is to have the ESP go into deep sleep when CAN activity stops, and then when CAN activity is detected, wake-up the ESP32 and...

Also very interested in using ADC2 simultaneously with wifi!

Specifically in arduino...

thanks
