YAAC AT90USB162 HM55B I call the board I use a Yaac - Yet Another Arduino Clone. It's based on the AT90USB162. I'm looking at making cheap Arduinos and that was the first result. I've documented the Yacc on the London Hackspace Wiki, where it was developed: http://wiki.hackspace.org.uk/wiki/Projects/YAAC Steps for running sketches on the Yaac are described. It is based primarily on the Teensy, another device based on the AT90USB162 capable of running sketches. I use the dfu-programmer to burn hex code onto the device. ************* ** CREDITS ** ************* Code piggybacking on the: 1. teensyduino-0018 2. arduino-0018 3. teensy Original code written by kiilo, lifted from: http://www.arduino.cc/playground/Main/HM55B Original calibration routine in datasheet converted to C by Scott Ferguson, lifted from http://www.societyofrobots.com/robotforum/index.php?topic=11392.0 I made a minor modification to obtain the first and last elements of the raw and offsets arrays, this allows linear interpolation for angles near +-180 degrees. **************** ** DATASHEETS ** **************** AT90USB162 http://www.atmel.com/dyn/resources/prod_documents/doc7707.pdf HM55B http://www.hobbyengineering.com/specs/PX-29123.pdf Daniel Sikar 01.01.2011 ~ onto the new decade. dsikar@gmail.com
