Freertos resource usage

Postby kernels » Wed Oct 02, 2019 7:23 am

Hi,

Brand new ESP32 user here . . .

I have the hello-world example running on my development board, and looking now at playing with the peripherals.
I note that when I do a printf, some string shows up in the terminal, note also that freertos is running in the background. This suggests that there must be some peripherals inside the ESP32 already tied up doing certain tasks.

Is there a document somewhere that tells me which resources are tied up by freertos, which uart is used for the log etc ?

Thanks

Figured it out ... for anyone else wondering about this, both the things I was wondering about are defined in the project configuration (idf.py menuconfig), in my case, UART0 is used for the console and TIMER0 is used by freertos.
