rprintf macro

[White-Rabbit-Scientific]

I have no idea where the rprintf macro documentation is, or has rprintf been deprecated? It is mentioned twice on this page:

Good question... I think that depends on what logger you have setup, and I guess 'defmt' would be the more common thing to use in the documentation.

rprintln comes from the rtt-target crate: https://docs.rs/rtt-target/latest/rtt_target/macro.rprintln.html

Agreed that we could probably update those examples to use defmt instead.
