Guys please help me! My bachelor thesis is to implement the communication between two ATmega32 via TWI/I2C interface and print out a ECG Signal on a display connected to the Slave. I am unfortunately pretty lost, and it's due Feb 28th Sad So maybe could anyone have a look at my code and tell me what I did wrong?

Hi, Whats wrong? What's not working? Do you have scope plots of the communication? Schematics? Try to reduce frequency for testing purposes to 10kHz. Br

well I am trying to release a interrup tat the slave which would effect a print out on the display (for test uses 5 4 3 2 1 ) but this isn't working. I thought freq is either 100 or 400kHz?

These are maximum frequencies for standard and fast mode. There is also a high speed mode. Clock can be zero, which will be useless of course. Please refer to philips I2C spec.
