I just ran into the same issue as well, just like moggiozzi. I too had two external interrupts wired into GPIO pins, both running at moderate speeds, configured with gpio_install_isr_service()/gpio_isr_handler_add(). However, I set up test pin outputs with an oscilloscope and I was able to catch ...

Hello,

Ok, message for others looking for the same problem.
I think that I found the issue...

I needed to add this line:

CONFIG_ADC_CONTINUOUS_ISR_IRAM_SAFE=y

In the sdkconfig file in visual studio code / ESP-IDF...
To make the whole ISR IRAM safe...

OMG. Cyrille, I'm going to ...

The ESP32 features 4 64-Bit timers, each with a 16-Bit prescaler and lots of different options for timer configuration. So far so good.
As I understand it i can only attach one ISR (which is called when a certain alarm value is reached by the timer) to each timer. As i have worked with AVR ...

To manage different build configurations in an ESP-IDF CMake project, it's usually done via command-line options or scripting within CMakeLists.txt rather than through IDE-specific "build configurations.


Thank you for that input. I was suspecting that and given I'm a bit of a CMAKE ignoramus ...

Hello all. I tried searching the various forums for answers to my questions, but the search engine keeps crashing if I enter more than one word in my advance search string. So, if this is a duplicate question, please forgive me. I tried!

I have a ESP-IDF CMAKE project for which I want to create ...

Wow. I'm not sure how I feel about this given I lost about 5 days of project progress because of this. (I had posted here for help about 4 days into the nightmare.)

It turns out the issue with the characteristics not having the correct properties flags was not at all due to the ESP32 and its code ...

I redeveloping an existing product with existing smartphone apps that previously used a different BT BLE module. I'm using an ESP32 now which is generally new to me. I've done plenty of 8-bit ESP8266 Arduino projects in the past, but this is my first foray into the ESP-IDE and the ESP-IDF with a ...

I had this same issue as well, and I had started out with the Hello World project using the following:
Espressif-IDE V2.5.0
ESP-IDF V4.4

I somehow resolved it by doing the following:

I created a totally new project with its own unique name (choosing not to use a template for now). NOTE that ...
