Overview
Description
The ISL29501-ST-EV1Z is a distance measurement reference design. It combines the ISL29501 Time of Flight (ToF) based signal processing chip with an OSRAM SFH 4550 IR emitting LED and OSRAM SFH 213FA photodiode. The circuit board is enclosed in an opaque plastic chassis designed to optically isolate components. Included is a USB flash drive containing the evaluation software for a PC and related technical documents.
The ISL29501-ST-EV1Z board also allows quick evaluation of the ISL29501 performance for a 5m sensing system.

Hello, my name is Celine Baron. I am applications interim manager for optical products. I am going to show you now how to operate our Time of Flight ISL29501 Sand Tiger Reference Board. This is the evaluation kit you just received. In this evaluation kit you will find multiple components. The first one is a USB key that contains our software GUI to operate the board as well as the relevant technical documentation to perform your own evaluation.
You will also find, of course, our ISL29501 Sand Tiger board. If you open it, which is not necessary for the evaluation, you will be able to identify the optical components which are part of the system, a photo diode and an LED. The ISL29501 chip is located on the other side of the PCB. In the kit, you will find also a USB cable, that will allow you to connect the board to a PC for power and communication purposes. Last, you will find a black target. This black target will be used if you want to perform a manual calibration of the board.
I am going to show you now, how to quickly operate the board. First of all, install the GUI on your computer from the USB key and connect the board. Then you can open the tof.exe file that will start the GUI. And first you will read and accept our license. You will scroll down and click on 'Accept'. Then the board is ready to operate. You can confirm that the board is powered up, looking at the red LED that we have here. Let me demonstrate now how the part works.
First, I will load a profile clicking on 'File', 'Load Profile', and I select one of the two profiles available, then I just have to click on 'Start' and the board is completely operational. A first example of application is to point the board towards the target.
You can see two signals on the GUI, the magnitude and the distance in meters. Here I am measuring the distance between the board and the target. If now I introduce an object, my hand for instance, between the board and the target, you will see that the distance measure drops, because now I'm measuring the distance between the board and my hand. If my hand goes closer and closer to the board, the measure of distance obviously decreases.
More information on the GUI functionality is provided in the software manual. Thank you for watching.
