Re: A stack overflow in task msg_send has been detected.
What's the stack size of the task, that is calling esp_wifi_start() ?

get entered WIFI password
Hi, I have an WIFI AP running on the ESP32 and I want to know, if it is possible to somehow get the info out of the wifi stack, which password a user is typing in, when he is trying to connect to the AP. Espacially when the typed in password is wrong... Already tried to find something helpful in esp...

Re: Interrupt behaviour, when more then one interrupt happen
Arduino is basically mapping to IDF api and because of I am calling "attachInterrupt" for every ISR-init, I expect same prio for all ISR's.
And in that case, processing one ISR after the other is exactly my desired behaviour
Many thanks!

Interrupt behaviour, when more then one interrupt happen
Hi all, I trying to find out, what will happen, when more then one interrupt occurs at the same time. For example I have 2 external ISR's initialized: attachInterrupt (pin1, ISR1, RISING); attachInterrupt (pin2, ISR2, RISING); In case ISR1 becomes active and does something. What happens, when ISR2 a...

Re: How to read PWM duty and frequency from pin?
Otherwise I have to go the "hard way" and implement edge-rising/falling interrupts + calculation of duty and freq.
Didn't expect, that there is nothing available

Re: How to read PWM duty and frequency from pin?
Is there any example or a library?
Cannot find anything
For sure, I am not the first, who want to do something like this.

How to read PWM duty and frequency from pin?
Hi,
I want to read PWM duty and freq from GPIO22. I want to attach a sensor there, that measures 2 things and encodes that to duty (10-90%) and freq (50-250Hz) values.
Does anybody has an example code for me how to do that?
Thanks in advance!

Re: Flash ESP32 WROOM32E on custom PCB
EDIT: Solved
I didn't connected the GND of the PCB with the GND of the flasher.

Re: Flash ESP32 WROOM32E on custom PCB
Hi, not measured with oscilloscope, yet, but I rudimentally checked the soldering for shorts etc., but the electrical continuity is fine. The CP2102 is on an external "flasher" and not part of the PCB. I also tried 3 different CP2102-flashers. I use only Tx and Rx lines of the CP2102 and I just real...

[SOLVED] Flash ESP32 WROOM32E on custom PCB
Hi, I have a custom PCB with a ESP32 WROOM32E module and cannot flash it. GPIO1 (=Tx) is connected to Rx of CP2102. GPIO3 (=Rx) is connected to Tx of CP2102. ...and I can see the boot messages... EN and GPIO0 have pullups. I pull both LOW, keep GPIO0 LOW and switch EN to HIGH. --> jumps in download ...
