Re: ESP32 Arduino SSID, PASSWORD not update

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 ...

Re: md5 Error while flashing ESP32-WROVER

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

Re: Processor utilization in percent

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

Re: How to re-enable GPIO after deep sleep?

WiFive wrote:Well you have to include driver/rtc_io.h. the way it is written it is a function declaration not a function call so it doesn't do anything.

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

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

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

How to re-enable GPIO after deep sleep?

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...

Re: ADC2 with WiFi workaround

Yes, I realize it will work fine with wifi disabled... ;) Im trying to figure out if its possible for both to work together....maybe by turning wifi off temporarily, reading ADC2, then turning wifi back on, etc. I need both functions...wifi and ADC2. I dont need them to work at the same time, but I ...

ADC2 with WiFi workaround

Hi, I have a custom PCB that has some DIP switches (via a resistor network) tied to some GPIO's on ADC2. I also need OTA flashing (WiFi) to work, so end users can easily update the firmware in their devices. I just now discovered the ADC2 and WiFi after my PCB design has been finished and in product...

Re: About the CAN controller.

Ok finally figured out what I was doing wrong, im stupid... my_frame.FIR.B.FF = CAN_frame_ext; my_frame.MsgID = 271732576; my_frame.FIR.B.DLC = 8; my_frame.data = {4 , 7 , 33, 4, 255, 255, 255, 255}; ESP32Can.CANWriteFrame(&my_frame); That compiles and works. But for some reason it wont compile with...
