I wanted to let users know about another and IMHO a much better alternative to Eclipse or PlatformIO. It's VisualGDB https://visualgdb.com/ I have been using VisualGDB for a couple years now for embedded Linux boards. They have added support for the ESP32. I have been using this for 3 months now wit...

FWIW, I have been using VisualGDB because not so long ago they added support for the ESP32. It makes life so much simpler using their platform. I am telling you guys this because when it comes to menuconfig you can see all the options there so easily this way. I made a short video of that here. http...

- using -jx or not, didn't change too much. Strange, -jx should make a great improvement. Just to be clear your not actually typing "make -jx" right ? your instead doing something like "make -j8" or "make -j16". You should open task manger when you start the make, and ensure all your cores are bein...

You can also change the default stack sizes is menuconfig.

you are sending data 4 times which is causing part of your delay. spi_device_polling_transmit(spi, &transA[bufferIndex]); spi_device_polling_transmit(spi, &transB[bufferIndex]); spi_device_polling_transmit(spi, &transC[bufferIndex]); spi_device_polling_transmit(spi, &transD[bufferIndex]); You can mi...

He might have a WROVER board.

Typically, the higher numbered com port is the serial port.

I think -jx is x = 2 x cores because each core supports two threads.

yes, All the options are in the docs.

It's better when you provide more information. What is your exact board you have?
