ESP32 UART-USB Brige How to use

[stefan.erni]

Hi Martin

My Uart program works again on both PCs.
There are no more problems with pressing the reset button.

But I can't compile the tiny program.

Do you know how I can add it to the Flowcode menu config ?

Are there any C code commands like for CPU speed setup? Then I wouldn't have to change the menu.

Hi Stefan,

Sorry - I'm away from home at the moment - and no access to anything to test...
What are you getting in the menuconfig ? I think you need a fullclean / rebuild (or change another menu setting, rebuild) after adding the tinyusb library before it shows up?

Hi Martin, Hi Ben

I've already made some progress.
Instead of the ESP3S3 in general, I'll try just the ESP3S3 Mini first. The pin layout is clearer on that chip.

I took a closer look at the ESP32S3-Mini, and the pins for RX/TX are :

UART0 mapped to GPIO 43 (TX) and GPIO 44 (RX).

But I'm still having trouble with the configuration menu. I can't add the USB Tiny option in config-menue from Flowcode.
