Hi Christoph,
The HMC58XX driver is polling the sensor, so their is no need of the
DRDY pin. Also the flag USE_I2C1 is already define by the subsystem,
so you should not be necessary to define it again.

Hi Felix,
thank you very much. As usual your response was very helpful.I was
just using a really old version, since then it didn't build. Now
I'm using the current v3.9 and it builds. But there are still some
problems: If I define USE_I2C1 the LPC won't start at all, I
wasn't able to reproduce this with a TWOG. Might it be a
HW-Problem? I think I should use i2c1 since it should be 3.3V I2C.
Second: I'm using this (http://www.sparkfun.com/products/9371)
Breakout Board from Sparkfun. It doesn't have the DRDY-Pin. I was
able to solder a wire to the pad and could solder it accordingly,
but: Will it work if I define HMC5843_NO_IRQ without DRDY for the
AHRS?
Last but not least I saw the "original b2_v1.2 has a 1.8V Vreg. Is
it really needed?
If there is somebody, who has answers for this questions help
would be highly appreciated.
Cheers
Christoph

Hi Christoph,
the driver for the booz imu v1.2 on LPC21xx uses the arch
independent driver hcm58xx, so you don't need an arch file...
See conf/firmwares/subsystems/shared/imu_b2_v1.2.makefile
Cheers, Felix

Hi everyone,
currently I'm trying to get some old booz Hardware to
work. Everything is fine and works, but the mag
doesn't. It's a Booz PCB set v1.1 . So the mag is
currently a MS2100. I can see the LPC sends somesthing
like 0x4B to the mag, but it doesn't pull DRDY. So I
guess the MS2100 is broken. I have a HMC5843 here. So
what I want to try to do is to just change the type of
the IMU from v1.1 (MS2100) to v1.2 (HMC5843). But the
arch file for the HMC on the LPC seems to miss. Am I
making a misstake or do I have to implement it? Or has
somebody already implemented it? Every help would be
appreciated.
Cheers
Christoph
