MT9M034 (Li-cam-m034) not responding on I2C

  • I recently purchased two mt9m034 cameras from leopard and I am unable to get either to respond over I2C.

    I've tried reading from the camera at both the main address 0x20 and its alternate address (which shouldn't work but tried it anyways) and I don't receive an ack after sending out the devices address.  I've verified all my connections to the camera and probed the I2C bus on the camera module using an o-scope and saw valid signals but received no ack.

    Anyone have experience with this camera?

    Thanks,

  • Well, figured it out.  The datasheet specifies the WRITE address as 0x20, which means the actual device address is 0x10.

    :P Hopefully this helps someone else.

  • did you ever manage to get the register reference for that camera?

    i cant seem to find it

    and i'm having hard time coding the drivers for that camera

    maybe you got something you can send me look as reference?

    Thanks,
