defmt-rtt-target
defmt
logger implementation using rtt-target
.
The official defmt-rtt
crate has its own RTT
implementation that is not externally exposed. This is done so that users can't corrupt the defmt log stream
by manually writing to the RTT channel. This library exists as an alternate option for when you do need
control over RTT, for example to log extra non-defmt data on other channels, or have a host->target "down channel".
If all you need is logging, you should use defmt-rtt
instead of this.
Usage
- Initialize
rtt_target
in your code - Call
defmt_rtt_target::init()
with theUpChannel
you want to use for RTT printing. This should be channel 0, as that's the one all defmt tools use. - Now you can log with the standard defmt macros.
Note that all log output before calling defmt_rtt_target::init()
is discarded.
