Specify the location of the device driver to be C:\Program Files\MAX7315 MAX7315 (or the directory chosen during installation) using the Browse button. 11) Start the MAX7315 MAX7315 EV kit software by opening its icon in the Start menu. The GUI main window appears, as shown in Figure 1. Evaluate: MAX7315 MAX7315 MAX7315 MAX7315 Evaluation Kit/Evaluation System Refer to the MAX7315 MAX7315 IC data sheet for a detailed I2C slave address map. On the bottom of the main window, the user can see the activity of the I2C interface and the status of the EV kit. In the main window of the software, there are five tabs that let the user configure all the registers of the MAX7315 MAX7315. They are Config/Master, O8 Intensity, Ports Configuration, Blink Phase 0/1, Registers Direct Access, and Help. Config/Master, O8 Intensity Tab The Config/Master, O8 Intensity tab shown in Figure 1 contains the Configuration (0x0F) group box and the Master, O8 Intensity (0x0E) group box. When Blink Enable is checked, Auto Flip is selectable. When Auto Flip is checked, the user can choose the blinking frequency as desired. When Global Intensity Enable is checked, bits 0 through 3 of the master/O8 intensity register (0x0E) control the global LED intensity. When Global Intensity Enable and O8 as Interrupt Output are unchecked, the bits 0 through 3 of the master/O8 intensity register (0x0E) control the O8 LED intensity. Figure 2. Ports Configuration Tab 4 _ MAX7315 MAX7315 Evaluation Kit/Evaluation System Blink Phase 0/1 Tab The Blink Phase 0/1 tab shown in Figure 3 contains the RGB LED D1 Configuration, the RGB LED D2 Configuration, and the White LED D3, D4 Configuration group boxes. These three group boxes control the Blink Phase 0 (0x01), Blink Phase 1 (0x09), and output intensity (0x10, 0x11, 0x012, 0x13) registers. They directly control LED D1, D2, D3, and D4. Figure 3. Blink Phase 0/1 Tab _ 5 Evaluate: MAX7315 MAX7315 Ports Configuration Tab In the Input Enable (0x03) group box, when a port is checked, the port is set as an input port. When a port is unchecked, the port is set as an output port. In the Input State (0x00) group box, the user can read the incoming logic levels of all the ports, regardless of whether the port is defined as an input or an output by the ports configuration register (0x03). Evaluate: MAX7315 MAX7315 MAX7315 MAX7315 Evaluation Kit/Evaluation System Registers Direct Access Tab Power Supplies The Registers Direct Access tab shown in Figure 4 contains all ten registers of the MAX7315 MAX7315. The user can directly write to the ten registers by inputting desired values and then clicking the Write All button. The user can read all ten registers by clicking the Read All button. The power supply for all LEDs must be powered by a user-provided 3.2V to 5.5V power supply that connects to the VLED pad. The MAX7315 MAX7315 can be either powered from the CMAXQUSB interface board or from a usersupplied 2.0V to 3.6V power supply that connects to the VCC pad, as shown in Table 2. Help Tab The Help tab contains the MAX7315 MAX7315 EV kit software revision and Maxim Integrated Product's website information.
