MCP2200 looks like a valiant contender to the FT232R series, both permit GP= IO pin programming from the host which is interesting for a number of reasons.= The price is also very interesting for MCP2200 imho. Unlike the FT232R the MCP2= 200 seems to provide GPIO access from Linux drivers too. Has anyone done something *other* than serial RS232 to USB conversion using these chips? The way back to the easy peasy IO interfacing, lost when parallel ports disappeared, seems to have reappeared. It took a while but, as they say, be= tter later than never. -- Peter --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
