    Problem with Del Sig ADC reading negative DC.

    vi.lu

      I'm trying to use ADC to read a negative DC values but it doesn't display the correct negative values on the LCD. I brought the Agnd to an external. I'm generating this dc voltage from a function generator. I attached my project files . I'm not very good at C coding so i just found an example project and modified a little bit. Please tell me how i can fix this problem. I'm using POSC 3 on the Cy8Ckit-001 Development board.
