I been snooping the net and found a number of websites with code and goodies for the 430. Olimex has some great proto boards for the 430, all sizes and shapes. They also had some source (I found the link to it on the SparkFun website, go figger!) That does software UART, serial EEPROM and RTC routines for the F1121 but with not much massaging should run on the F2xxx series. In fact it was listed on SparkFun with a protoboard for the F2131. Links for this are on my MSP430 Blog at ------ cheers ... 73 de brian riley, n1bq , underhill center, vermont Tech Blog Home of the K107 LCD Controller Kit FT817 Power Conditioner Kit Tab Robot Laser Tag Kit MSP430 Chips and Connectors -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
