If it's a really simple one-off test, then I wire it up manually on a protoboard (the kind with a .1 inch grid of sockets connected in strips). Otherwise, I get a PC board made. For prototyping and testing I try to stick to 2 layer thru hole, but that is not always possible. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
