10hz logging about f9p_rawx_logger

[PaulZC]

Hi Stefal,
Apologies - the code in this repo isn't as up to date as it should be. You can find the latest version in the ZED-F9P_FeatherWing_USB repo. The I2C logger code uses the new multiSetVal functions for the F9 in the SparkFun u-blox library. Please check if this version meets your needs.
My plan is to update the code in this repo as soon as I have time. I'll close this issue once I've done that. (I'm away from home at the moment.)
Best wishes,
Paul

Hi Stefal,
Thanks again for your comments.
I finally found time to update the RAWX_Logger_F9P_I2C code so it matches the code in the ZED-F9P_FeatherWing_USB repo.
I have also updated RAWX_Logger_F9P so it uses the SparkFun Ublox library and have removed the dependence on the Adafruit library.
I wouldn't recommend logging RAWX data to a single file for longer than 60 minutes. If you have a power glitch while logging, you could lose all your data. Joining the .ubx files together is easy to do so I'd recommend doing that if you can.
The delayed stop is a nice feature but I won't be adding it as I'd like to maintain compatibility with the RAWX_Logger_Switches.
I hope the I2C code fixes your 10Hz logging issues. Please let me know if it does.
All the best,
Paul

Hi, and thank you for the update!
I'm still stuck at 8Hz. It looks like an arduino sd card bandwidth limit.

Sorry for answering so late, I'm a little busy on other projects, perhaps this one could interesting you: RTKBase

Hi @Stefal ,
It may not be an SD card issue. It is probably because you have too many constellations enabled?
I have had RAWX running at 20Hz, but you can only do this using GPS only. If I have all constellations enabled, I2C starts to fail at about 5Hz. Sometimes you can go faster, but it depends how many SV's are in view and so how much RAWX data is being produced.
Good luck with your project! RTKBase looks nice! ;-)
Best wishes,
Paul
