How to initialize TVP5158 with dm6437

Which device are you using, TVP5146 or TVP5158?

BR,

Steve

 HI Steve:

      The device is TVP5158, Function name does not modify! How to initialize TVP5158.

You seem to be writing to a reserved register E.g. register BEh is reserved.

Why are you changing the chroma hue (register 14h)?

Where did this code come from?

Have you examined the command files which are included in the EVM software download?

Is the DM configured to receive data in the same format as you are configuring the TVP to send? I don't know anything about the DM VIP so can't help with that unfortunately.

BR,

Steve

Hi Steve:

    Steve: "Why are you changing the chroma hue (register 14h)?"
    chen an:  Now I use the default value!

    Steve: "Where did this code come from?"
    chen an: Code from dm6446 initial TVP5158, rewritten come from linux! 

    Steve: "Have you examined the command files which are included in the EVM software download?"
    chen an:TVP5158 connection the i2c of dm6437,  i2c is normal and the frequency is right.Because this drive is successful initial tvp5150.

 This is my dm6347 initialization tvp5158 procedure,but did not successfully initialized TVP5158.  
 Could You  give me some advice or reference examples?

Chen an,

When I said "Have you examined the command files which are included in the EVM software download?" I really meant for you to download the EVM software and look for the example ".cmd" files for various modes. These files are simply text files which contain a list of I2C commands necessary to configure to various mode. I suggest starting with these files as an example of what is necessary to configure the TVP5158.

BR,

Steve
