If you're not planning to make several of these devices, you might be able to save yourself some time and money by buying a PCMCIA to RS-232 converter. Then you can just concentrate on the serial portion of things. Socket makes several of these devices. Here's a link to the one that does what I think you need. http://www.socketcom.com/product/SL0700-004.asp I didn't check, but you'll probably find them cheaper at Amazon or Buy.com. -Mike -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU] On Behalf Of Alex Muirhead Sent: Thursday, April 08, 2004 8:26 AM To: PICLIST@MITVMA.MIT.EDU Subject: [PIC:] PCMCIA peripheral Hi I want to make a PCMCIA card that will sample values/capture serial data for my pocket pc. I am having a huge problem getting information on the PCMCIA interface and communication specs, the book everyone recommends "Inside PC Card" I am un able to get hold off because its out of print, and the only copy our uni library had has gone missing! (to someone in our department!) What I was wondering is does anyone have another other suggestions on good sources of information (free! 0 budget for this). Someone must of done this before with a PIC, can they give me some pointers please ;) Thanks Alex -- http://www.piclist.com hint: The PICList is archived three different ways.
