Hello,

 

I have difficulty with my video lock at startup. Here is my clock configuration below. I do have an external XTAL 28.xMHz. The I2C register 0x13 (W) is not clear for me. I have install "ADV Register Control 3.56" an see some XTAL stuff at this location (Write only).

 

  fResult = I2CWriteOneByte8bitAddr(hI2C, slaveAddr, 0x1D, 0x40, &iResult); //; ADI Control 2 - EN28XTAL, wLLC
//fResult = I2CWriteOneByte8bitAddr(hI2C, slaveAddr, 0x13, 0x04, &iResult); //; See doc
  fResult = I2CWriteOneByte8bitAddr(hI2C, slaveAddr, 0x51, 0x9B, &iResult); //; Lock count

 

Thanks, Guy
