Hi im working with an Arduino due and a c3038 camera. I found this discussion and have gone through the code. http://arduino.cc/forum/index.php?topic=8100.0
As it happens the i2c write page does not work on the ide since it is written for avr libraries. I've been looking for some help to re-write some of this code so that it is compatible with Due, but I've been unable to find the macros to be replaced for the "_BV", TWSR TWBR etc.
Am i simply missing an include file? or are there separate macros defined for the above?
