ESP32 CPU frequency

Hey ! I would like to know how I choose the frequency of the esp32 (I mean when I have to choose 80,160 or 240Mhz ?).

And also most important, is there a really change in terms of energy if I choose 240Mhz instead of 160Mhz ?

Thanks :D

Re: Problem using Make Flash in command line

Ok thank you for your answer, I also can't use the make monitor command with JTAG but with a serial interface using TXd and RXD pin ?
Or is there an other solution to see my messages in the code I send to the ESP32 elsewhere than in the debug mode ?

Re: Problem using Make Flash in command line

And when I'm running

Code: Select all

ls /dev/tty*
it's the ttyUSB0 that appear and disappear when I plugged and unplugged my esp32.
