Run the no‐OS Demonstration Standalone (AD7606B)

In addition to the DataStorm DAQ development kit running either in standalone mode or remotely via Ethernet cable, it can also run for no-OS software while connected to computer via an usb cable.

Configuration for no-OS software access

The AD7606B Evaluation Platform in this configuration is comprised of the following components:

• Analog Devices EVAL-AD7606BFMCZ (also Known As EVAL-AD7606B) data converter board
• DataStorm DAQ (Trenz Intel® Cyclone® V SoC TEI0022 Development Board) (includes 12VDC power supply)
• Digilent Analog Discovery 2 Signal Generator with dual outputs
• Digilent Discovery BNC adapter board
• One (1) BNC Male to SMB Female Cables
• USB connectors
• Separate Windows PC running Digilent WaveForms App and Terminal Program

Configure BOOTSEL DIP Switches

Select the SD card as the boot source for the processor.

Configure FMC_VADJ DIP Switches

The FMC_VADJ power rails provide power to the EVAL-AD7606BFMCZ via the FMC interface. This is an adjustable voltage. It must be set to 3.3V. Modify the VID_SW DIP switch settings to select 3.3V.

Assemble the Hardware

Follow the steps in the order shown below.

• Insert the Micro SD card into the SD card slot
• Insert the EVAL-AD7606BFMCZ FMC connector into the FMC mating connector on the DataStorm DAQ board
• Connect the Signal Generator to the EVAL-AD7606BFMCZ SMA connectors
• Ensure that Jumper JP5 is removed, Jumper JP1 is in position A to remove standby, Jumper JP6 is in position B to get internal voltage reference on AD7606B, Jumper JP3 in position B, and Jumper JP2 is in position A to get +12V from FMC on the EVAL-AD7606BFMCZ board, for it to be powered via the FMC connector.

• Connect the power supply to the DataStorm DAQ
• Plug the AC-DC adapter into an AC outlet

Signal Source

The Analog Discovery 2 is used as a signal generator to drive the AD7606B input.

Install (if not already done) the Digilent WaveForms App.

Open the WaveForms App and Click on Wavegen in the left margin which opens a waveform window

Click on Channels and select 1
Select Type as Sine
Select Frequency or Period
Set Amplitude to 1V
Set Offset to 0V
Click Run All

Run the no-OS demonstration

Software for no-OS access

There are a few software components that need to be installed in order to run this demo successfully:

1. A SW terminal like Tera Term VT or Putty

Connect to the target terminal

• A wired Micro USB serial port connection between the separate Windows PC and the embedded target is required
• Launch a terminal program like Tera Term VT or Putty and connect via a serial port to interact with the demo
• Select 115200 baud
• Select the appropriate target COM port

Run the demonstration

Simply power up the unit. No additional configuration is required. The bare metal application runs automatically and continuously streams analog measurement results across the serial port to be received and displayed in the terminal program running on the separate Windows PC.

Serial Interface

Parallel Interface

NOTE: HDL design for AD7606B is based on 4-SDI lane for all channels to receive at throughput 800Ksps in Serial interface. The no-OS example supports only for 4-SDI lane.
