Otherwise, open the USB_Driver_Help_200.PDF document in the Windows Start | Programs menu to verify that the USB driver was installed successfully. 5) Start the EV kit software by opening its icon in the Start | Programs menu. The EV kit software main window appears, as shown in Figure 1. 6) Select Clear+RGB+IR in the Operating Mode combo box at the upper-left corner of the software. 7) In the Color Map Display tab sheet, check the Auto Convert checkbox in the Single Conversion group box to read the ADC values.   4 MAX44008 Evaluation System Evaluates: MAX44008 Figure 1. MAX44008 EV Kit Software Main Window (Color Map Display Tab) Maxim Integrated   5 MAX44008 Evaluation System Evaluates: MAX44008 Detailed Description of Software The MAX44008 EV kit software (Figure 1) contains an I2C Interface group box, a Status group box, and four tab sheets (Color Map Display, Time Sequence Display, Ambient Sensor Configuration, and Register Map) to configure the MAX44008 and display the ADC data received from the device. I2C Interface In the I2C Interface group box, choose the appropriate I2C slave address in the I2C Address group box. Enter the register address in the Reg Address edit box and press the Read button to read the register. The returned value is shown in the Data edit box. To write a data value into a register, enter the register address in the Reg Address edit box, enter the data value into the Data edit box, and press the Write button. Operating Mode Use the Operating Mode drop-down list to select one of the three operating modes. The operating modes are: Clear, Clear+IR, and Clear+RGB+IR. Color Map Display Tab The Single Conversion group box on the Color Map Display tab sheet (Figure 1) displays the ADC values for a single sample. Press the Convert button to update the values in the Ambient, Temperature, and CCT group boxes. The received RGB ADC values are converted to the chromaticity coordinates (x, y) values using the 3-by-3 Correlation Constant Matrix located in the upper-right corner of the chromaticity diagram. The calculated x, y value is plotted on the chromaticity diagram in a circle shape. Overwrite the values in the matrix and press the Save button to save the matrix settings. Press the Load button to restore the previously saved matrix. See the following for the RGB to chromaticity coordinate conversion formulas and CCT calculation formulas: X Y =   Z Check the Auto Convert checkbox to automatically and repeatedly do the ADC conversion and update the values in the Ambient, Temperature, and CCT group boxes. Check the Save to File checkbox to save the received data to a file. To use the Color Balance function, the user must first connect the daughter board to the EV kit. See the MAX44008 Daughter Board section for details on how to connect the daughter board. The Color Balance feature allows the user to select a color on the chromaticity diagram by clicking on the diagram. The selected color is boxed by a square shape. If the LED Color Balance button is pressed, the on-board RGB LED outputs the selected color. The RGB sensor on the device is used to get feedback to determine whether the RGB LED is outputting the right color. Time Sequence Display Tab In the Time Sequence Display tab sheet (Figure 2), the user can select the desired number of conversions in the Number of Samples drop-down list. The rate that the controller reads the ADC data from the MAX44008 is selected from the Read Rate drop-down list in the Continuous Conversion group box. Press the Convert Start button to start sampling from the ADC channel selected from the Channel Select drop-down list. After the Convert Start button is pressed, the sampled data is plotted on the graph. If the Save to File checkbox is checked, the received ADC data is saved to a file after each conversion.  3 BY 3  R   CM  × G     MATRIX B  X x= X+Y+Z Y y= X+Y+Z CCT =449n 3 + 3525n 2 + 6823.3n + 5520.33 where n = x − 0.3320 0.1858 − y Maxim Integrated   6 MAX44008 Evaluation System Evaluates: MAX44008 Figure 2.

Check the Ambient Interrupt Enable checkbox to enable the detection of ambient interrupt events. Check the IR Compensation Enable checkbox to enable IR compensation. Check the Temperature Sensor Enable checkbox to enable the temperature sensor. In the Receive Configuration group box, use the AMBTIM[2:0] drop-down list to set the integration time and resolution for the ambient ADC. The AMBPGA[1:0] drop-down list sets the gain of the ambient light sensing measurement. Use the Ambient Thresholds group box to set the upper and lower ambient interrupt thresholds. The ambient measurement of the ADC channel that is being compared to the thresholds is selected from the Ambient Interrupt Select drop-down list in the Status group box. After the Ambient Interrupt Enable checkbox is checked, if the ambient measurement is higher than the upper threshold or lower than the lower threshold, the interrupt event is recorded (provided the persist timer condition is met). The interrupt bit is reset only after reading the interrupt status register. In the Upper Threshold group box, use the UPTHR[13:0] track bar to select the desired upper ambient interrupt threshold. Press the adjacent Set button to set the UPTHR register. Similarly, use the LOTHR[13:0] track bar in the Lower Threshold group box to select the desired lower ambient interrupt threshold. Press the adjacent Set button to set the LOTHR register. Use the AMBPST[1:0] drop-down list in the Timer Threshold group box to set the persist value that con- Maxim Integrated trols how readily the ambient interrupt logic reacts to a detected event. In the Gain Control group box, check the TRIM Enable checkbox to force the part to use the trim value set in the trim gain registers. Use the track bars and the adjacent Set buttons to set the trim gain registers for the corresponding ambient ADC channels. Status In the Status group box, press the Read button to read the status of the interrupt pin, INT. If the interrupt signal is asserted, the status register (0x00) is read and displayed in the Power/Interrupt Status group box. The measurement of the ADC channel selected from the Ambient Interrupt Select drop-down list is compared to the ambient interrupt thresholds. When the Ambient Interrupt Enable checkbox is checked, if the ambient measurement is higher than the upper threshold or lower than the lower threshold, the interrupt event is recorded (provided the persist timer condition is met). The Red, Green, and Blue track bars and the Set RGB buttons are used to manually adjust the brightness of the on-board RGB LED. Use the RGB LED On/Off radio group box to turn on/off the RGB LED. Register Map The Register Map tab sheet (Figure 4) contains a register map of the device. The tab is organized from left to right with register names, bit names, register addresses, edit boxes, and Read and Write buttons. The bit names are used to display the current state of each bit (visible text = 1). In addition, a register’s bits can be individually toggled by single-clicking on the bit’s name. The edit boxes are used to display a register’s state and are updated after a bit click or Read button press. The user can also change the value of the register by entering a value in the edit box and pressing the adjacent Write button.   8 MAX44008 Evaluation System Evaluates: MAX44008 Figure 3.
