Subject: HELP: Interface a CMOS sensor with the DM355
Hello,
I come towards you because I work at present on the interfacing between
the demo board DM355 and the CMOS sensor MT9J003 from Micron (Aptina) to
make of the video. 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.
Ibrahima SAKHO
