MAXREFDES130 Bottom View

I am using arduino-uno board for evaluation.

when inserting it to the header pins, the USB connector  is touching the PCB Tracks & Points. So to avoid short I covered the connector with Plastic-tape

All the components required for testing are arranged on work table

After that arduino is connected to the MAXREFDES130 shield

24 Vdc is applied to the MAXREFDES130 via DC adopter & arduino is Connected to PC via USB cable. MAXREFDES130 Grid Eye is connected to MAXREFDES130 via RJ11 cable on board & Power is applied.

  LEDs indicate the Proper power presence in MAXREFDES130 and MAXREFDES131

OWGridEye_SingleDevice Firm-ware is uploaded to arduino  and Serial monitor shows following output


after that MAXREFDES131_GUI_Firmware is uploaded to arduino and Demo app is executed to obtain following results

select the correct COM port in drop down menu

After correct COM port selection, Click " Enumerate Sensors" to find and display sensors on One-Wire bus

After proper sensor enumeration press the Receive data button

Thus the intensity values of 8*8 sensor array is depicted graphically  on GUI

Movements of hand above sensor can be clearly seen in the  images

After that MAXREFDES130 firmware is uploaded to arduino to obtain following Output on serial monitor

0-10V analog output generation capability is tested by selecting option 10.

A multimeter is connected in DC voltage mode between channel 0 & GND using crocodile-style clips with hook up wires and is tested for various voltages as shown in the figure

Channel 0 is providing 5V DC

Channel 0 is providing  9.5 V DC

The analog outputs has pretty good accuracy.
