Linux/DLPC6401: Command of the DLPC6401 through I2C

Part Number: DLPC6401

Tool/software: Linux

Hi there,

I'm trying to communicate with the DLPC6401 using the i2c-tools on Linux.

I can scan the i2c line and detect the device at address 0x1a (0x34 >> 1).

What I'd like to do is a Long Axis Image Flip. In the datasheet, it corresponds to the register 0x08.

To flip the screen, I've tried the following: i2cset -y 1 0x1a 0x08 0x01

But the command seems to be ignored..

Any clue?

Kind regards,
