DIMU calibration

[hogster]

Just done a static calibration and have produced these logs ... they look fine except the Rate graphs – why is the X rate a negative copy of the other values?!

Many thanks!

David

PS. This was using the "aqv7.0.r371.b1702-hwv6.1-dimu1.1.hex" firmware.

@David: I don´t understand your "rate" curves. Image show acc x,y,z ticked. Rate should be close to 0 for static (see atatched one of mines)

New firmware revision (372), PARAMS.TXT onboard, and the real-time rate values seem much better (close to 0). Will do another static test tomorrow, fingers crossed!

Hi,

here's the result from my yesterday evening freeze! Board is orientated horizontally! Firmware is r372 for DIMU.
@David: My rate curves look exactly as yours.

TEMP

RATE

ACC

MAG

Isn't it the idea of static calibration to get a set or parameters from scratch? I don't really understand why we need a static calibration when loading Jussi's parameters to the board (since they are the result of such a process).

Just did another static log file and it all looks good now.

Hi David,
have you done the log with Jussi's parameters loaded?

Joerg it does not matter if parameters are load or not cause what you see (LOG_IMU_Rate in example) are the raw voltages from the sensor without any parameters added to it.
