Can we program ESP32 UART in assembly language ?

Postby Rushi3499 » Mon May 16, 2022 6:45 am

I tried the assembly language on ESP32-c3-devKitC-02, but I cannot see the output. So, can we program the UART in assembly for the same esp32?

No, sorry, while it's possible, no one really programs the ESP32 series in assembly. If you want UART code, you'll likely have to write it yourself.

(Btw, is there a reason you're so adamant on writing it in assembly rather than e.g. using the existing C drivers?)

A google search for “risc-v uart assembly” turned up lots of examples for me.
I think it is a popular homework assignment.
