Recently I had to bitbang I2C through a voltage level translating buffer that had a direction setting pin that needed to be manipulated when sampling SDA on input. The uC's hardware I2C block obviously couldn't handle that extra signaling oddity. Not the fastest approach but then this I2C application wasn't that high speed to begin with. Good times indeed!
