This page is intended to link to some circuits and code I've developed for the NMI 68HC11 and 68HC12 Single Board Computers. Some circuits I've developed that may be of some interest include interfacing a direct-digital-synthesizer, ADC's, and DAC's via the SPI bus; interfacing to a compact-flash memory card; and interfaces to pressure and temperature sensors. Eventually, I'll get all that on here.

Browse around as your interest takes you ... keep in mind that the cards I used are no longer available and the CPU chips on these cards contained a proprietary code set of FORTH that, I'm sure, you won't be able to order from Onstar/Motorola anymore.
