There are only a few differences between the two devices. Throughout this document, the devices will be referred to as TCS377x. The screen images in this document use a TCS3771 device, but where the device controls differ, the appropriate portion of the TCS3772 screen will also be shown. INITIAL HARDWARE SETUP The software should be installed prior to connecting any hardware to the computer. Follow the instructions found in the Quick Start Guide (QSG). The software will check the system for required component to support the graphical user interface (GUI). The software comes in the kit on a company logo flash drive. The hardware consists of the Controller EVM v2.1 motherboard, the TCS377x evaluation daughterboard and an A to mini-B USB interface cable. FIGURE 1: TCS3772EVM COMPONENTS When the USB cable is connected the green LED next to the USB connector should light up indicating that power is being received via the USB interface, and the controller board processor is running. If the green LED does not light up check the USB cable connections, unplug the USB cable and try again. If, after re-trying, the LED does not light, check the PC for USB error messages. See resources section at end of this document for additional assistance. Note, after the DigitalLightSensor application program begins executing, it will turn this LED off so that it does not interfere with testing. ams PROVIDES CUSTOMER SUPPORT IN VARIED TECHNICAL AREAS.
