CMPS01 Compass Module

Archiver

Hi-de-hi Stampers !

Has anyone successfully interfaced a BS2-SX with a CMPS01 Compass Module ?
I have one of these modules and got it working on an OOPIC from a sample
circuit diagram and code but talking I2C.

My robot brain is a BS2-SX and I'm not ready to rework the entire machine to
run from the OOPIC just yet. The documentation tells me that there is a PWM
output available but also talks of decoupling the 5v supply due to a current
spike of up to 400mA during coil switching. This makes me wary of just
wiring it straight to the stamp !

Any information would be most gratefully received. If you'd like to look at
the docs for the compass, you can find them at

Thanks in advance.

Regards,
Justin.

I've got it working in the 8 bit mode(0-255) with the BS2 using the I2C
routines from www.high-techgarage.com . I haven't got to th 2 byte mode
yet.
I also got it going in both modes with the BX24 using Prof. Anderson's I2C
routines.
The chip on board is a PIC, the same as the BS2, so direct connect should
not be a problem for i/o but you shouldn't run it off the BS?'s regulator.
