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.
All files including arduino codes, libraries, Demo GUI & schematics are included in the attachment as .zip files
