Looking for basic resources on I2C Bus

how to configure the video encoder through i2c

I don't know anything about I2C Bus.
From where should i get some initial knowledge

Moreover my video decoder and the PGA are attached through I2C bus
to configure video decoder from FPGA
How should i do that

I2C BUS

do u want to implement I2C bus controller?if yes i am having some material on that.

Re: I2C BUS

My video decoder chip is attached to FPGA via I2C(for programming)
I need to enable the output of the video decoder (which works only in slave mode)
The output is enabled via following way

I need to build an I2C master into my design(verilog programm). Then use that to load the value 0x6D into register 0x03 of the TVP5150. That will enable the YOUT[7:0] outputs

This was the reply send from the XESS company

Now i want to do it.
I did't understand what is 0×6D and how to use it

Re: I2C BUS

Hello,

I did't understand what is 0×6D and how to use it

it's just a number in hexdecimal notation. In Verilog you could write 8'h6d instead. You have to consult the video-encoder manual to know what it means. I understand, that you have to write a single byte to register address 03 in video controller.

Regards,
Frank

Re: I2C BUS

phillips invent it in 1979 !

you refer there web site to explore more about it !

or you refer any iic device data sheet such as AT24C01 ,AT24C02 etc.
