Connect the EVM as shown in
1. Physically connect P2 of the PHI to J5 of the ADS1278 EVM.
2. Install the screws to provide a robust connection. Connect the USB on the PHI to the computer.
a. LED D5 on the PHI lights up, indicating that the PHI is powered up.
b. LEDs D1 and D2 on the PHI start blinking to indicate that the PHI is booted up and communicating with
the PC.
3. Power the ADS1278 EVM through the J10 terminal with 6V.
4. Start the software GUI. Notice that the LEDs on the PHI blink slowly when the FPGA firmware is loaded on
the PHI. Loading takes a few seconds.
5. Connect the signal generator. The input range is 0 V to 5 V. A common input is a 4.9V
offset. This signal is adjusted just below the full-scale range to avoid clipping.
