EVB90621 User Guide 1. Scope This document describes the design and use of the MLX90621 evaluation board(EVB) and demo software. For a general description about the functionality of the MLX90621 please refer to the MLX90621 datasheet. 2. Applications The EVB90621 is intended to be used as an application example of the MLX90621 Low Noise High Speed FIR array. It was developed to demonstrate the features of the device with the help of the demonstration software. EVB90621 Layout 1 USB connector 2 Reset button o o o 3 MLX90621 device. This board is compatible with all versions of MLX90621 (40 , 60 and 100 Field of View) 4 MLX90621 notch. Please mind the correct orientation of the device when putting it on the EVB 5 MLX90621 power led. When this LED is ON, the device is supplied by the EVB 6 Test points 7 Extension connector 8 Communication Busy and Link LEDs. Those LEDs indicate the status of the EVB 9 EVB power LED. When this LED is ON, the EVB is supplied by the USB. EVB90621 Demonstration Software Please go to: www.melexis.com and search for the latest version of the demo software: EVB90621 User Guide Download and install it on a Windows-based PC platform. Normally, the installation creates a shortcut to the program on the Desktop. If this is not the case, the program can be started from C: > Program Files > Melexis > Mlx90621 Demo > Mlx9062x Demo.exe 3. Running the Software Plug the EVB in a free USB port of the computer. If the connection is ok, the Power LED(9) shines and the Busy LED(8) shines for a while and stops. Now start the software. When the initialization procedure finishes, the Link LED (8) shines and the Device Power LED (5) is on too. The application window is ready for operation: 1 Individual pixel readout. Depending on Application settings(5), those could be temperature or LSB 2 Row and column bar graphs 3 Ambient temperature sensor readout 4 EEPROM dump button. We highly recommend that the EEPROM of the device is back-upped before further playing with the device REVISION 1 APRIL 2015 Page 2 of 4 390119062101
