Ah well, back to work today. A couple of months back I downloaded a PIC I2C library from the net, which I've lost in a HD crash, including all my links. On the Document it was called "Software Parts & Peripherals", "Callable Software Functions extracted from the ECH". It had files in it called: Opensw12C, putcSW12C, getcSW12C etc. to name a few. Anybody got a link for this info? Thanks Quentin
