4.1 ADS8681WEVM-PDK Operation

The following instructions are a step-by-step guide for connecting the ADS8681WEVM-PDK to the computer and evaluating the performance of the ADS8681W:

  1. Connect the ADS8681WEVM to the PHI. Install the two screws as indicated in Figure 4-1.
  2. Use the provided USB cable to connect the PHI to the computer
    • LED D5 on the PHI lights up indicating that the PHI has powered up
    • LEDs D1 and D2 on the PHI start blinking, indicating the PHI is booted up and communicating with the EVM
