rtt-log
Log facade implementation for the Segger RTT protocol supported by the J-Link, ST-Link and other debug probes. It is based on rtt-target.
Note
rtt-target introduced log integration with version 0.6.1, making this crate obsolete.
Please refer to the rtt-target docs for further details.
Usage
// Init the logger with maximum level (Trace).
rtt_log::init();
// Alternatively, init the logger with specific level.
rtt_log::init_with_level(log::LevelFilter::Debug);
// Log something.
log::debug!("Application started");
Use a tool like probe-rs on the host to print the messages.
Note
RTT uses a global symbol _SEGGER_RTT that can only appear once in a compiled binary. Therefore, if you want to use functions from rtt-target directly, import them from rtt-log instead of adding rtt-target as a separate dependency. Otherwise, a linker error about duplicate symbols will occur.
use rtt_log::rtt_target::rprintln;
rprintln!("Hello, world!");
