Looks like the UART is working when I make a connection using Minicom.When I do that, and unplug and replug power to the module it sends a 0x55 or ASCII U to state that it's ready. That char appears on the UART screen every time I plug back in the device. Looks like the issue is actually with the rppal crate.Code:
minicom -b 57600 -o -D /dev/ttyAMA0
I am no expert at this sort of configuration, and am not a Rust user. (Other than simply running code distributed by others, such as pigg.)
But I was going to suggest looking at the output from
Code:
ls -al /dev/ttyA*And was also going to query what linux device name gets used by
Code:
use rppal::uart::{Parity, Uart};let uart = Uart::new(115_200, Parity::None, 8, 1)?;Statistics: Posted by B.Goode — Tue Nov 05, 2024 3:00 pm
