How do I connect the Digilent PmodAD1 to my host board?

Connecting the Digilent PmodAD1 digital converter expansion module to your host board involves a few key steps. First, understanding the pinout is crucial. The PmodAD1 has two headers, J1 and J2, with distinct pin configurations. Header J1 includes Chip Select (CS), Input Data 1 (D0), Input Data 2 (D1), Serial Clock (SCK), Ground (GND), and Power Supply (VCC). Header J2 includes Input Data 1 (A0), Ground (GND), Input Data 2 (A1), Ground (GND), Ground (GND), and Positive Power Supply (VCC). Ensure the external power supply for the PmodAD1 is within the range of 2.35 to 5.25 volts to guarantee proper functionality. The PmodAD1 uses an SPI-like communication protocol. Data lines are designed as Master-In-Slave-Out. The module provides 12 bits of information over 16 clock cycles, with four leading zeroes followed by the 12-bit data, MSB first. The first leading zero is clocked out on the falling edge of the Chip Select (CS) signal, with subsequent bits clocked out on the falling edge of the Serial Clock (SCK) signal. The pin headers have a 100 mil spacing. The PCB dimensions are 0.95 inches long parallel to the pins and 0.80 inches long perpendicular to the pin header. Refer to the Digilent PmodAD1 manual for detailed pinout diagrams and specifications to ensure a successful connection and accurate analog-to-digital conversion with your host board.
