Honeywell makes a series of amplified/digitized air pressure sensors but=20 after an hour of searching, I cannot find a complete datasheet that=20 describes the digital interface. They call out the pins on the device=20 but I cannot find anything relating to the actual digital interface -=20 msb/lsb? word size? commands? etc. Does anyone here have a pointer to where I could locate this information? Thanks! --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
