Hi All, As far as I can tell, their are no i2c hardware driver support for the at91sam9263 TWI. Are their any known problems with this interface?
It won't work under linux, since the interrupt latency is so long that you get overrun problems. If you are going to sit in a loop, waiting for the H/W to complete, you might as well do a S/W I2C, so I guess noone bothered.
