DLPC3433: I2C Initialization Sequence For DLPC3433 - MIPI DSI

Part Number: DLPC3433

Hello, 

What would a proper initialization sequence for the DLPC3433 look like for the I2C commands to send the DLPC3433? 

Would something like the following look proper? Am I missing something? We could really use some help!

I2C_BUS=1
I2C_ADDR=0x1d
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0x01 0x00
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0xd7 0x00
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0x10 0x00 0x00 0x00 0x00 0x56 0x03 0xe0 0x01 i
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0x12 0x00 0x00 0x00 0x00 0x56 0x03 0xe0 0x01 i
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0x2e 0x56 0x03 0xe0 0x01 i
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0xbd 0xc8 0x00 i
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0x05 0x00
i2cset -y ${I2C_BUS} ${I2C_ADDR} 0x52 0x07

Thank you, 
Chris

  • Hi Chris,

    Welcome back to the forum.

    This appears correct. Based on this and your other post I am assuming that you are not seeing your video being fed on your DLPC3433 system with an intended 850x480 resolution. Is this correct?

    Regards,
