Does anyone have experience with the Parallax/Hitachi HM55B Compass?
I've been trying to convert Parallax code (which I have earlier
experience with) to the BX-24. One really 'frustating' thing is the
limited ability of BasicX's PusleOut()/PulseIn() commands. I'm about
to 'Bit-bang' it but I was hoping to use the above. Interfacing to
the compass is fairly trivial especially considering the BX-24's
floating point capability. The real problem is shifting odd number of
bits greater than 8 as well as defining the clock phase (aka SPI)
which the BX-24 does not support in the above functions. Thanks,

- Tom

It seems to me that it is hard to make a lot of parallax sensors work with
the BX-24. But if you find the answer for it. Could you please email me the
source code for it?

Ryan, I have not had much trouble with other Parallax sensors other
than getting around the PulseIn()/PulseOut() differences and the
Stamp's method of converting floating point info. Once I have it
figured out, I'll post it on my web site and leave a message here.

Thanks :)
dont sopose u have used the SSIR sensor with the BX-24?

Ryan, I'm not familiar with the "SSIR" sensor. I posted an example of
using the Sharp GP2D02 and I've played with the GP2D12 but the former
has similar range and is much easier to talk to without using an A/D,
simple software, and draws much less current.
