Hi Tim, you have to change the used processor pins. The protocol is a bit banging type (not i2c). You have to change the current clock and data protocol and change the used pins of the processor. Please read the documentation (Phillips UM10139) of the lpc2148 to know how to program a pin as output (clock) and as input output and tristate for the data line. You have only to change the pin definition. But sometimes there are other register words used for different pins. So sometimes the macros im paparazzi code can fail. Heinrich Bonin, Tim A. schrieb:
