spdlog output to Serial

[kowalski100]

Hi,

I was exploring to use the spdlog library on some baremetal firmware without OS. Is it possible to use/redirect spdlog to serial port?
Our C++ version cannot go beyond C++11 due to low level requirements.

Thanks

Implementing a custom sink for this seems like a good option. Should be straight forward

Hi @gabime

custom sink - you mean adding a glue logic b/w serial hardware and spdlog output?

[gabime]

Yes. See the docs on how to implement a custom sink (to send the log to a serial port).

[kowalski100]

sure. thanks for the help @gabime.

I just have one more quick question for your expert opinion: Is there any advantage to using the spdlog library (with serial) beyond formatting text, since the same can be achieved with sprintf- like functions?

[gabime]

spdlog have many features. It all depends on the needs
