Hi everyone!
Im new to the Sparkfun forum, and this is my first post! I just bought a 9dof sensor stick, and I am having some trouble communicating with the HMC5843 chip on it via I2C. Im using a PIC24F. I can talk to the ITG-3200 and ADXL435's (via I2C) just fine, but I am getting no ACK from the magnetometer. Ive triple checked all the registers, tried bit-banging and hardware I2C, and baud rates from 50Khz to 400Khz, but nothing has worked. Ive noticed the HMC5843 is a relatively old product, but I don't think thats the reason. Has anyone has this type of problem before? Thanks!
