Mag readings are not update?????

[engamila]

After 20ms cycle time, mag readings are not update.I try this put a 'delay(20)' on main loop.Anybody know what is the reason for this??????

Could you please give more information?

Explain what flight control board you are using?
What software version you are using?
Has it ever worked before?
How can you tell that the mag readings are not updating?
Have you calibrated the compass?
Does all the other functionality work?
Some details about what you changed in the config.h file.
The code should work, why are you putting delay(20) in the main loop?

Thanks,
Shaun
