Blackfin 561 - I2C Protocol Issues - miracle_sksim - Sep 7 7:35:43 2007



Hi,

I have use part of the rouines in I2C protocol routines as below 
shows. I DL the I2c code from the DSP forum.

void Init_Camera(void) 
{ 

I2C_Init(0x40); // init ADV7183A for write 
I2C_Write(0x04,0x00); // select video input to AIN5 

I2C_Init(0x54); //init ADV7179 for write 
I2C_Write(0x00,0x03); // select output to DAC_C 

} 

where those I2C_ init and write are call upon in the I2C.c file.

My qns is just by doing that the video input and output is set to my 
preference am I right ?

Or is there any other functions that i need to do ?

And I am using the Video In Out example where the default ports are 
set up for input and output of the video.

So here is another qns before the PPI being set up,  I initialize the 
camera in order to set up the ports that what i want for the camera 
am i right?

My camera format is NTSC. Which i dont see any display coming out 
from my LCD TV.

And i hope someone can guide or help me in here. Thanks

Regards,
Josh
