3 ) Connect the EV kit s 40-pin female connector (J) to the CMODUSB board s 40-pin male connector (P4). 4) Install the evaluation software on your computer by running the INSTALL.EXE program on the installation CD-ROM. It is highly recommended to use the default installation path. If you desire to modify the default path, do not use a depth of more than two subdirectories. The program files are copied and icons are created for them in the Windows Start menu Programs Maxim Evaluation Kit. 5) Connect the 5V power supply between the EV kit s +5V and pads.turn on the 5V power supply. Do not connect the USB cable before this step. 6) Connect the included USB cable from the PC to the CMODUSB board. A Building Driver Database window pops up in addition to a New Hardware Found message. If you do not see any window that is similar to the one described above after 0 seconds, remove the USB cable from the CMODUSB board and reconnect it again. Administrator privileges are required to install the USB device driver on Windows 000 and XP. Refer to the document Troubleshooting USB.PDF included with the software for more information. 7) 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\ using the Browse button. 8) Start the EV kit software by opening its icon in the Windows Start menu Programs Maxim Evaluation Kit. If the 6-color demo mode is visible, then quick start is complete. Loading Scripts (Optional) ) Press the Load 8-bit Write Script button on the 8 and 6-bit addr modes tab. ) Load the script file bit_step_box.cm located in the C:\Program Files\ directory. ) Press the Run 8-bit Write Script (6bytes) button in the 8-bit Write Script window. 4) Press the Load Next Script button and load the script file bit_step_box.cm located in the C:\Program Files\ directory. 5) Press the Run 8-bit Write Script (6bytes) button in the 8-bit Write Script window. Detailed Description of Software The evaluation software s main window shown in Figure displays tabs for 8-bit, 6-bit, and 4-bit addressing modes as well as individual tabs for each register in the s register address map (0x00 through 0x0F). Table describes the controls that are always present on the evaluation software s main window. The 8 and 6-bit addr modes tab, shown in Figure, allows the user to execute 8-bit and 6-bit address mode operations. The 8-bit address mode is the quickest method of updating a plane of display memory in the and is write only. During the 8-bit address Table. EV Kit Software Main Window Control Descriptions CONTROL Allows the user to select the active register tab. Shows the CMODUSB debugging tools. Gives access to the Helpfile and the About box. Automatically sets the global driver devices and the global driver rows registers of the master to the correct values when cascading boards. Resets all the registers to the software reset settings. For example: -bits/pixel bicolor mode Register 0x0D = 0xC 4 driver devices (N-) Register 0x0E = 0x0 driver rows (N-) Register 0x0F = 0x0 Resets all the registers to the IC power-on reset (POR) settings shown in the data sheet. Displays the CMODUSB connection status. CMOD means that it supports both the CMODUSB or CMOD boards. Exits the program.

4 Figure. Evaluation Software Main Window mode, data is written to the display memory using indirection through the global display indirect address register. This display indirect address is autoincremented after each 8-bit write to allow continuous image data dumps into the plane of display memory in the. The 6-bit address mode is capable of reading or writing command/data bytes to the s registers. A 6-bit write can be global (updates all s with the same data) or local (only one ). A 6-bit read always uses indirection through the global driver indirect address register to select only one. Refer to the Register Addressing Modes section of the data sheet for additional information. The 4-bit addr modes ( bit/pixel) tab shown in Figure, and the 4-bit addr modes ( bit/pixel) tab shown in Figure, allow the user to execute 4-bit address mode operations. A 4-bit operation is always a direct read or write of address/data to the s display memory because the memory address is included in the 4-bit operation. Refer to the Register Addressing Modes section of the data sheet for additional information. 4

7 Detailed Description of Hardware EV System The EV system is a PC-controlled LED display system consisting of a EV kit and the Maxim CMODUSB serial interface board. CMODUSB Serial Interface Board The CMODUSB serial interface board uses a proprietary design to provide SPI - and I C-compatible interfaces to demonstrate various Maxim devices. Maxim reserves the right to change the implementation of this module at any time with no advance notice. CMODUSB Power Supply The CMODUSB board uses a MAX658 linear regulator. Jumper J selects between a 5V or.v system supply voltage. Do not plug a wall cube into the P power jack because power is provided from the USB port. Table. CMODUSB Jumper J (System Supply Voltage) J SYSTEM SUPPLY VOLTAGE (DV DD ) - 5V -*.V *Make sure the J jumper on the CMODUSB board is in the - position when using the EV kit. EV Kit The EV kit contains four devices (U U4), a 6 x 6 dot-matrix display (D D4), a stepdown voltage regulator (U), a 4MHz oscillator (U0), and logic buffers (U5 U9, U). The EV kit requires a +5V supply (rated for.5a per EV kit) and up to five EV kits can be cascaded allowing the user to evaluate up to 0 devices. Tables through 9 explain the functionality of each jumper when using only one EV kit. Table.

10 Cascading EV Kit Boards The EV kit board was carefully designed to cascade up to five EV kits. Tables through 9 explain the functionality of each jumper when using only one EV kit and Table 0 shows a summary of all the default settings. The 5V supply requires a current capability of.5a per EV kit. For example, five cascaded EV kits require a 5V supply capable of supplying.5a. If the digit 0 and digit segment current settings are changed from 40mA to 0mA on all devices, then the current requirement is cut in half. For example, one EV kit would require.5a and five EV kits would require 6.5A. Table 0.
