Hi,
I want to put a sine wave in a psoc pin input, then send the result to the pc. But i can only recieve the positive values. I already have the adc configure to signed values, is there any more configuration i should change?
Thank You

You will have to level-shift the sine input using a resistor ladder so that the voltage is between GND <= sin <= VDDA
No GPIO may be driven below GND, could damage the chip.
