Need info about DAC programming in C

[jsbmim]

Hi,
I would like to program a DAC, in C, to convert in a audio signal from a ATEMEGA8 with I2C interface.If someone could gime me a hint...
I'm a beginner and I don't know where to begin from. I know something about I2C interfacing but is very difficil to start programming it...

Just a hint for someone who is trying to learn!
Please!

Best regards,
Ann

Hi,

I2C is not too complicated.
you just need to care about the start bit , stop bit and trensition of DATA with CLK.

ON web you can find some source code for 8051 for I2C.
also you may use a micro with built in I2C. , it's very simple.
I think ATMEGA8 may have some micros with built in I2C
