If you *do* wind up having to do it yourself with a PIC, look at the=20 PIC10f322 family. They have native PWM hardware built-in, which may=20 dramatically reduce your coding time. No USART or I2C hardware,=20 unfortunately. The SOT23-6 package is easy to work with. BTW - I've been purchasing SOT23-6 zero insertion force sockets (for=20 programming) from=20 US $24.99 each=20 in 3-lot. I then made up little adapter boards that map the pins to=20 a 6-pin header to match a PICkit 2 or 3. dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
