Check this documentation: https://docs.espressif.com/projects/arduino-esp32/en/latest/esp-idf_component.html I also had errors when I tried to use Arduino as a component and I had to go and comments some libraries out (That I don't use anyways). I did that since I was trying to compile some example ...

Try adding the --timestamps option. For me this is working in the Linux command line: $ idf.py monitor --timestamps -p /dev/ttyUSB0 Executing action: monitor --- idf_monitor on /dev/ttyUSB0 115200 --- --- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H --- 2021-08-17 16:03:05 I (27) bo...

I also had this problem when compiling components that use some IRAM and also adding RainMaker (Which also adds Bluetooth libraries and such) Only solution I found is to move what is possible to the SPI external RAM detailed in the manual page you mentioned in the: CONFIG_SPIRAM_* (menuconfig option...

Nice Jochem! Glad it worked.

You can edit the title of this forum entry and add [SOLVED] at the beginning so it's easier to recognize that you found a solution.

It sounds doable. But IMHO the best way to "sniff" this will be using a logic analyzer and connect it directly to the USB of your computer. I've sniffed some time ago SPI using ESP32 as an slave: https://github.com/martinberlin/esp32-spi-slave Bu I'm not sure if that will help. I would get a 10 $ lo...

Thanks nopnop!
Didn't know about this one. I will try it out and compare speeds.

Interested to know:
What could be the possible real-world applications to run the Linux kernel in ESP32 ?

Can I even use Update.h and TinyGSM libraries on esp-idf or these are purely for Arduino use? Why don’t you add it as a component and just try it out? Just keep in mind that it should respect the Build system and component structure for the IDF. If the library uses arduino references that parts sho...

Please read the Build system documentation part specifically where it specifies what is the right directory structure: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/build-system.html#example-project myProject/ - CMakeLists.txt - sdkconfig - components/ - component1/ - CMakeL...

Hello @orbitcoms First of all check again IDF documentation on SPI master I believe there are examples for reading a value. I also have an epaper component for esp-IDF that reads temperature on some einks that have 4 wire SPI since this displays do not work well when they are outside an acceptable t...
