FILE DESCRIPTION INSTALL.EXE Instal l s the E V ki t fi l es on your com p uter MAX697.EXE Application program FTDXX.INF USB device driver file UNINST.INI Uninstalls the EV kit software U S B_D r i ver _H el p.p D F MAX697 EV Kit Files USB driver installation help file Quick Start Required Equipment Before beginning, the following equipment is needed: MAX697 EV kit (USB cable included) A user-supplied Windows 000/XP/Vista-compatible PC 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 MAX697 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, 697Rxx.ZIP. Save the EV kit software to a temporary folder and uncompress the ZIP file. ) Install the EV kit software on your computer by running the INSTALL.EXE program inside the temporary folder. The program files are copied and icons are created in the Windows Start Programs menu. ) Verify that all jumpers (JU JU) are in their default positions, as shown in Table. ) Connect the USB cable from the PC to the 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.

3 ) 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\MAX697 (default installation directory) using the Browse button. During device driver installation, Windows may show a warning message indicating that the device driver Maxim uses does not contain a digital signature. This is not an error condition and it is safe to proceed with installation. Refer to the USB_Driver_Help.PDF document for additional information. 6) Start the EV kit software by opening its icon in the Start Programs menu. The EV kit software main window should appear as shown in Figure. 7) Wait for the EV kit to fully connect and click on the DEMO button. Verify that all the LEDs turn on, one by one, starting from LED0 to LED in the software and the EV kit. Detailed Description of Software The main window of the evaluation software (Figure ) displays the state of each LED on the EV kit. Click the LED0 LED icons located in the main window to turn the LEDs on and off. A clear LED represents off and a red LED represents on. Other options include a DEMO and CLEAR button. Demo Button Clicking the DEMO button will always clear any previous ON state of the LEDs before going into its sequence. The LEDs will turn on, one by one, starting from LED0 to LED. At the end of the sequence, all LEDs will be on. If the Continuous Demo checkbox is checked before the DEMO button is pressed, the demo sequence will repeat continuously. During this routine, both DEMO and CLEAR buttons are disabled. To stop the demo, uncheck the Continuous Demo checkbox and the DEMO and CLEAR buttons will be enabled. Clear Button Clicking the CLEAR button will turn off all of the LEDs. When in demo mode, allow the sequence to finish before clicking the CLEAR button. If the Continuous Demo checkbox is checked and the DEMO button is pressed, the CLEAR button will be disabled. To enable the CLEAR button, uncheck the Continuous Demo checkbox. Figure. MAX697 EV Kit Software Main Window

4 Options RGB Option Move the shunt of JU to the - position and apply a 6V power supply at the VLED pad. Next, reconfigure the shunt of JU9, JU0, and JU to the - position. Restart the program and click Options RGB Option from the main window. The RGB Option window (Figure ) displays the state of the RGB LEDs. The red LEDs are connected to PORT, the green LEDs are connected to PORT, and the blue LEDs are connected to PORT. If an LED icon is selected, that entire row will change states. A clear LED icon represents off and a colored icon represents on. RGB DEMO Button Clicking the RGB DEMO button will always clear any previous state of the LEDs before going into its sequence. The LEDs will blink the following sequence of LED: (red), (green), (blue), (red, green), (green, blue), (red, blue), and (red, green, blue). At the end of the sequence, all LEDs in PORT, PORT, and PORT should be on. If the Continuous RGB Demo checkbox is checked before the RGB DEMO button is pressed, the demo sequence will repeat continuously. During this routine, the RGB DEMO and CLEAR buttons are disabled. To stop the demo, uncheck the Continuous RGB Demo checkbox and the RGB DEMO and CLEAR buttons will be enabled. CLEAR Button Clicking the CLEAR button will turn off all the LEDs. When in demo mode, allow the sequence to finish before clicking the CLEAR button. If the Continuous RGB Demo checkbox is checked and the RGB DEMO button is pressed, the CLEAR button will be disabled. To enable the CLEAR button, uncheck the Continuous RGB Demo checkbox. Advanced Users Interface In Figure, a serial interface can be used by advanced users when clicking Options Interface (Advanced Users). Enter data into the Data bytes to be written edit box and press the Send Now button. Detailed Description of Hardware The MAX697 EV kit provides a proven layout for the MAX697. On-board level translators, serial-interface pads, and an easy-to-use USB-PC connection are included in the EV kit. User-Supplied Serial Interface To use the MAX697 EV kit with a user-supplied serial interface, first move the shunts of jumpers JU JU and JU to the - position. Next, apply a.v to V power supply at the VCC pad (see the User-Supplied Power Supply section). Lastly, connect user-supplied LE, SCLK, DIN, DOUT, and OE signals to the corresponding pads on the MAX697 EV kit board. User-Supplied Power Supply The MAX697 EV kit is powered completely from the USB port by default. Move the shunt of jumper JU to the - position and apply a.v to V power supply at the VCC pad. The user can also apply a supply voltage up to 6V to the VLED pad after reconfiguring the JU to the - position.
