I use the Arago project for it. The problem which I have is situated at the configuration of the I2C bus. Indeed, the register address of the CMOS sensor MT9J003 is on 16 bits and I do not succeed in communicating via this bus. I am parit of the driver that you developed for the MT9T031, but without succés. The communication with the sensor is of this kind: I2C Block Read (2 Comm bytes) ============================= This command reads a block of bytes from a device, from a designated register that is specified through the two Comm byte. S Addr Wr [A] Comm1 [A] Comm2 [A] S Addr Rd [A] [Data] A [Data] A ... A [Data] NA P Is this I2C function implemented in the I2C module ? May I use Arago project to manage to configure this I2C communication ? I shall really need your help and your councils. I thank you beforehand.
