MAXREFDES130 Bottom View

image

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

image

All the components required for testing are arranged on work table

image

After that arduino is connected to the MAXREFDES130 shield

image

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.

image

  LEDs indicate the Proper power presence in MAXREFDES130 and MAXREFDES131

image

image

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

image

image

 

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

image

select the correct COM port in drop down menu

image

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

image

After proper sensor enumeration press the Receive data button

image

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

image

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

image

image

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

image

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

image

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

image

image

image

Channel 0 is providing 5V DC

image

Channel 0 is providing  9.5 V DC

image

The analog outputs has pretty good accuracy.
