Once you start needing faster updates the resolution drops quickly. Thanks for the input, Adam. I've sampled the Maxim part and I'm also using the ADXL213 in a current design. It's an accurate, easy to incorporate little accelerometer. -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
