If you mean increasing the times, yes, should be enough. Since the clock is used as the "sync" between master and slave, the clock is the "dominating" pulse. So, the bigger you take the times, the longer it will take before a next clock pulse will be generated => slower I2C. But I2C is already very slow by default in that driver (some 60 kHz, I've measured, maybe a bit more...), so why would you like to do that? Just curious... :-) Best rgds, --Geert
