Interrupt latency on the ESP32 is a little higher than ESP8266, although there are also a lot of other variables which can effect interrupt timing. Without seeing and debugging the full code it's hard to tell what the problem might be. Regarding SoftwareSerial, did you know that ESP32 has 3 hardware...

However, I know this board will work in DIO, but when I make menuconfig and save the config and flash, it boots as QIO. Edit: make clean then repeating fixed it. Will leave post up in case anyone else has same problem changing between QIO and DIO. That's quite strange! Where you flashing with "make...

Sorry, I don't understand the question. Can you please clarify a few things: - What exactly is connected to the pin you have the interrupt attached to? - What exactly do you expect to happen? (ie what action do you take, and what do you expect to see the code do.) - What is currently happening? (ie ...

As chegewara says, the result of uxTaskGetStackHighWaterMark() is the minimum amount of free stack space for the lifetime of the task. Larger values == less stack used. A difference between ESP-IDF and vanilla FreeRTOS is that stack sizes are represented in bytes, not words. So there's no need to mu...

Hi gigijoe, The Pypi server now requires HTTPS, which very old versions of pip do not use. You can work around this situation by running: pip install --index-url=https://pypi.python.org/simple/ -r requirements.txt ( as suggested here .) Please note that Ubuntu 12.04 has been officially End Of Life s...

Hi recently, With the input filter disabled, the PCNT module should be able to count up to a 40MHz input clock (half the 80MHz APB frequency). I'm not sure why this specification isn't listed in the datasheet or the TRM. Do I understand that what you need to do is count the number of cycles from the...

Hi Adham, Can you please post the complete output from make? ESP-IDF recently added some python dependencies and built-in dependency checking, so this step is designed to print information about missing Python packages and a command to run in order to install them. However, it's possible that it's n...

Thanks for your response. Just wondering if we distribute encrypted firmware for serial flashing (no OTA, Wifi will be off on this device), would that be ok? Do you need to flash in the field updates, or only once in the factory? If only once, the default Secure Boot & Flash Encryption will be enou...

Hi RA5040,

I'm unsure what you mean by "Eclipse-Arduino". Can you post some examples of the functions you are measuring stack usage for, please?

What's the contents of your component CMakeLists.txt file? You'll need a line like this:
before the "register_component()" line, so that the build system knows that you want this directory added to the include path.
