TMS320C28343 - Make ADC work with sinusoidal input

Other Parts Discussed in Thread: ADS7865, TMS320C28343

I’m using on my graduation work a TMS320C28343. This board has 2 external ADC (ADS7865) and to work with then I’m using the example Bellow:


Now I’m trying to change this code to work with sinusoidal input. Using the graph to see the data i can only see a half wave with the example code.

Somebody know what i have to change on code and hardware to see a complete sinusoidal with the graph?


Thaks for helping.
