On IDF V.4.0 with flash encryption enabled, when I run: idf.py encrypted-flash monitor It compiles, but when it comes to flashing, it throws the following error: FileNotFoundError: [Errno 2] No such file or directory: 'flash_encrypted_project_args' esptool.py failed with exit code 1 I checked the bu...

Added a new manual entry for idf_env and it seems to be going now.

Having multiple versions of IDF installed side by side should generally be possible. If you are on Windows, the installer will create a shortcut to launch each version of ESP-IDF which you install. @ESP_igrr the old cmd shortcut for 4.0 looked like this: C:\Windows\system32\cmd.exe /k ""C:\Users\us...

What's the process for running multiple versions of the ESP-IDF on the same machine? We'd like to start the upgrade process to 4.3.1 but don't want to break the existing production build env. I was told it was as simple as having a separate ESP-IDF directory and path env. Don't think things are that...

FWIW, that example doesn't busy-loop: it uses blocking code where FreeRTOS simply doesn't execute the task until the ringbuffer has some data. You're right. It does use signalling. The whole process is so code intensive that I mostly get " RMT RX BUFFER FULL" errors. Our signal edges are only 52us ...

Is there a task-less and ring-buffer-less example of RMT RX? The peripheral example for IR remote employs a busy-looping task and a ring-buffer. The TRM however suggests things could be simpler if we didn't need to transmit/receive too much data AND we can get an interrupt when RX idle condition is ...

adding support for static memory to ESP-IDF

thanks for the heads up. Do you see an issue with using the HAL or LL layer version of I2C?

@vonnieda: Thanks for the link. Will look into it. Was hoping for a cleaner solution, though this by definition is what I asked for

Is there an alternate esp32 I2C driver that does not use malloc? we have an ESP32 application with contained memory and it seems to fail sometimes because of malloc failing to allocate memory for I2C. I haven't looked deeper to see if this is a heap fragmentation issue (is that even a thing in FreeR...

Edit: VCC is approx 3.12VDC. Typing a tilde (~) seems to get mapped to a minus (-) after it's posted.

What's the voltage that's supposed to be on there? If it's >3.3V (or <0V) the ESD protection stuff in the ESP32 could potentially kick in and source current. [Thanks ESP_Sprite] If the current is flowing _out_ of the input pin, then esp32 VCC voltage would by definition be higher than the LED volta...
