Hi,

I have to make a connection beetween an uc atmega164a and an FPGA with I2C interface uc-master and fpga slave
First,i have to program the uc but i didn t find a code in C and be able to test it.


So i have to find a code,with the i2c connection and send a number from the uc output and test if the number is send correctly on the osciloscope.

The code will be in c.Can anyone help me with that code,which is i2c communication and be able to send a number and test it on the oscilloscope?

Thank u very much,guys
