hello. I have to generate various tones (sounds) with the de2 carte.

Can you help me please because it's for my studies and i don't know how to do.

I have done the i2c communication. then i send a signal of 1khz frequency at the dacdat output but it doesnt function.

I don't know really which adress and register to programm to function like i want (send a frequency to the input codec and have a sound at the speakers), which clock to programm and what value.

thank you for your help
