 | | Vector2x SPI interrupt driven code —

| | | Well it works. A couple people have asked for it. Turns out the stupid V2X docs are wrong again! Like the product, but bad docs will kill it! Even if you don't have a V2X, I have seen enough traffic asking about using the SPI for things on the HB, (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

| | | | Not sure who you are? tomb? Anyways, I noticed mention of a compass.... I once looked into the idea of using a flux gate compass to obtain heading info. After finding that the inexpensive (affordable) models would only obtain info at a resolution of (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

| | | | Hey Tom How close is too close? How far away do you have it? Any problems with just pieces of metal, like casters or maybe a gel cel holder. (hint hint) Sounds like a pretty nifty little device. Just wondering if my setup would allow me to use it (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

| | | | (...) From my experience, the calibration is only needed if you need absolute heading data. Any non-moving metal in the immediate neighborhood will have a constant effect on the readings. I just care about maintaining the current heading (go (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)
