Look at Microchip application notes AN541 and specifically AN554 (I2C master mode implementation). I could mail you another master mode implementation using the Parallax assembly code, if you'd like me to... Can someone help me sort my PCLATH problem. I'm trying to access two look-up tables, each about 200 bytes long, in a 16C84. The first table is located in the fist 256 bytes of the prog memory and works OK, but the second one is a real bugger to access. I tried shifting the table around and modifying PCLATH, but don't seem to get it right. Please assist. Regards, Richard Ivanov, Cape Town <-- new politically correct sig
