I'm using the PMODAD1 ip core given by digilent and try to build a project using basys3 FPGA board. first i have create a simple 1 kHz sin wave with +/- 1V amplitude from Digilent Analog Descovery2 and use a PMODAD1 at 50 kHz sampling rate. when I read the integer value from the AD1 I got only the positive values, my question is:
1. Is the exemple given with the IP core is using 12-bits ADC?
2. What should I do to read a positive and negative value from the AD1?
I'm using the c programme given as exemple withe PMODAD1 IP core.
