Usage of PNI V2Xe compass

El Paisa

Has any one have done some programming using the propeller with the PNI V2Xe compass?
I am interested in learning how to use this device.

I have. I got it to work using Martin's BS2.Functions. I am planning to make it work with the newer shiftout/in objects sometime in the next couple of weeks. I am back to work on a 'bot that uses the V2XE, but have to finish up a few things before I get to the V2XE.

I'm not at the machine that has the code. I'll post it when I get home. You may want to try it using the shiftin/out objects. I had some issues, somewhat cloudy now (the 'bot has been back burnered for almost a year) that caused me to have to toggle the power to the compass sometimes to prevent it hanging. There is also something odd about inverted data or something, I can't remeber exactly. It affected the BS2P and the Prop, but not the BS2. I had many talks with PNI and sent them copies of the Prop and Bs2P code, you may be able to find it on their website.

Here is the code. Don't laugh, I'm not a brilliant coder. It is somewhat commented, but feel free to ask any questions, I *might* remember what I did. Also included is a few extra's, like a routine to determine which way is shortest to turn to reach a particular heading, i.e. if you are facing say 280 degrees and want to turn to 290 degrees, you want to go clockwise etc.
