3 Quick Start Required Equipment Before beginning, the following equipment is needed: Maxim MAX EV kit (includes USB type A-to-B cable) User-supplied Windows 000/XP/Vista-compatible computer with a spare USB port Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. Procedure The MAX EV kit is fully assembled and tested. Follow the steps below to verify board operation: ) Visit to download the latest version of the EV kit software, Rxx.zip. Save the EV kit software to a temporary folder and uncompress the zip file. ) Install the EV kit software on your computer by launching the Rxx.msi program inside the zip file. The program files are copied and icons are created in the Windows Start Programs menu. ) Ensure that the jumper settings are in the default positions, as shown in Table. ) Connect the USB cable from the PC to the MAX EV kit board. A Building Driver Database window pops up in addition to a New Hardware Found message when installing the USB driver for the first time. If you do not see a window that is similar to the one described above after 0s, remove the USB cable from the board and reconnect it. Administrator privileges are required to install the USB device driver on Windows 000/XP/Vista. ) Follow the directions of the Add New Hardware Wizard to install the USB device driver. Choose the Search for the best driver for your device option. Specify the location of the device driver to be C:\Program Files\Maxim MAXEVKIT (default installation directory) using the Browse button. During device driver installation, Windows XP shows a warning message indicating that the device driver Maxim uses does not contain a digital signature. This is not an error condition. It is safe to proceed with the installation. Refer to the USB_Driver_Help.PDF document for additional information ) Verify that the EV kit s LED is lit, indicating that the USB is connected and providing power. ) Start the EV kit software by clicking its icon in the Windows Start menu. ) The software should automatically connect to the board after a few seconds. ) In the Demonstration Mode group box, click on the Counter demonstration radio button. The -segment LED display will count in decimal, as shown in Figure. 0) In the Demonstration Mode group box, click on the PC Time demonstration radio button. The -segment LED will show the -hour time in hours, minutes, and seconds, as shown in Figure.

6 Detailed Description of Software The MAX EV kit software provides several demonstration modes. Selecting Click to toggle segments allows arbitrary patterns to be entered by clicking on the segments in the GUI display, then clicking the Apply button. Selecting the Counter demonstration, PC Time demonstration, or PC Date demonstration mode displays numeric data. The Loopback test all segments mode is used during EV kit testing to verify that all three MAX devices are daisy chained, and that each segment is individually controllable. The last two modes turn all segments off or all segments on. History Window Each time the -segment display is updated, the SPI sequence is displayed in hexadecimal, in time sequence. The first bytes control the last device in the daisy chain (U). The last bytes control the first device in the daisy chain (U). Detailed Description of Hardware Each MAX (U, U, and U) drives a dual -segment display (LED, LED, and LED). LED indicates USB V power is present. The FTDI FT (U) provides the USB engine. The USB V power is regulated down to.v and.v by U and U. The low-voltage RISC microcontroller, MAXQ000 (U), processes commands sent by a program running on the PC. Each particular EV kit has its own custom software specific to that kit. The firmware loaded on this board is identical to the MINIQUSB interface module. Using an External SPI Bus Instead of USB To disconnect from the on-board SPI bus, cut the links at jumper block J and jumper block JU. Connect JU, pins -, and provide V power to the and EXT_VLED oval pads. Connect the external SPI bus to the labeled test points of jumper block J.
