PX4 logging frequency
-
I need to log PX4 sensors and GPS data as fast as possible. Right now the logging intervals are too slow. I found this forum post: https://discuss.px4.io/t/high-speed-logging/25242/4 .
According to this post I should change the rates in this file:
https://github.com/PX4/PX4-Autopilot/blob/main/src/modules/logger/logged_topics.cppBut this means that have to recompile the whole PX4 firmware (right?) and then upload it. Isn't there an easier way? Isn't there a way to change the logging intervals from a configuration file or through parameters or something like that?
-
@boga Which log topics specifically are you wanting to increase the rates on? There is a PX4 parameter SDLOG_PROFILE that can enable some high rate logging topics.
-
@boga If SDLOG_PROFILE doesn't have what you are looking for then you can set up a custom set of log topics / rates from a file. You don't need to recompile PX4 to use it. https://docs.px4.io/main/en/dev_log/logging.html#sd-card-configuration
