Did you get the I2C handle and set tvp5154 write address?

This is example as below

// Write Enable to all 4 decoders
valE[0] = 0x0F;
_IIC_write(DM642_I2C_hI2C, _TVP5154_IIC_ADD_W, 0xFE, &valE[0], 1);

YES，I‘m sure. My design tool is ISE 13.3.This image is my I2C handle and TVP5154 set ..

I use Verilog HDL to program my design.May be some different.

PS: "address==8'h00" is not real register address, that is index address.The step is first sent device address B8,then sent register FE,data 0F,reture to sent device address B8,then register 7F,data 00,and return to sent device address B8 ,then register FE,data 0F,last sent register 00,data00,data 15..........
