Hi,

I have written code some time ago that compiled fine with esp-idf 3.3. I know that for compilation, you just have to create a
components directory and in each component, you need an empty component.mk . In the project dir. you have a CMakeLists.txt with a
content like this

Oh okay thanks.

Hi,

I have attached an interrupt on the GPIO36 following the tutorial here: https://github.com/espressif/esp-idf/tree/release/v3.3/examples/peripherals/gpio
I am using IDF 3.3, because I have dependencies on esp azure, which requires this version of the IDF.
When the interrupt is triggered, the ...

That’s great news. I will check it out. I haven’t done any benchmarking yet.

Hi,

There is a difference in the two reference sheets "Hardware design guidelines" and "ESP32-WROOM-32 datasheet".
Both can be found here:
