Back in the mists of time (or at least the Piclist archives) it was mentioned that Analog Devices have published the source code used on their little demo board with the 16c63 and an adxl202... anyone know where I can get this code ? I have searched in vain on the AD website. Regards, Simon -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
