1 year ago You have to decode the output with defmt-print. See the example runner script for artemis. Essentially: cat /dev/serial0 | defmt-print path/to/elf

Hello there, Thanks for providing the defmt_serial crate!
I am having a little trouble getting it to work at the moment. It seems to be only outputting tildes to my terminal.
Welcome to minicom 2.8

As I am very new to rust and embedded programming, I am sure the issue is on my end. Here is my code for a raspberry pi pico. Interestingly, the UART setup works if I comment out defmt_serial and uncomment the lines with uart.write_str(). I am able to see the word "Test" printed to minicom. Any ideas what I am doing wrong here? Any pointers in the right direction would be appreciated! //! Blinks the LED on a Pico board //! //!
