MAX44000 EV Kit Software Main Window __________________________________________________________________ Maxim Integrated Products  5 MAX44000 Evaluation System Evaluates: MAX44000 Proximity Sensor Configuration Tab The Proximity Sensor Configuration tab sheet (Figure 2) has all the functions to configure the proximity sensor of the device. In the Transmit Configuration group box, use the LED Drive Current (DRV[3:0]) track bar to select the desired IRLED drive current. The IR Proximity LED current is shown on the right of the track bar. Press the Set button to set the DRV register. The Proximity Threshold group box can be used to control the proximity interrupt function. Use the Receiver Threshold (PRXTHR[7:0]) track bar to select the proximity threshold level and press the adjacent Set button to set the PRXTHR register. After the Proximity Interrupt Enable checkbox is checked, if the Above the Receiver Threshold radio button is selected in the ABOVE / BELOW Proximity Receiver Select (ABOVE) group box, and the proximity measurement is greater than the value stored in the PRXTHR register, the interrupt event is recorded. Similarly, if the Below the Receiver Threshold radio button is selected, and the proximity measurement is less than the value stored in the PRXTHR register, the interrupt event is recorded. Use the PRXPST[1:0] dropdown list in the Timer Threshold group box to set the persist value that controls how readily the proximity interrupt logic reacts to a detected event. Ambient Sensor Configuration Tab The Ambient Sensor Configuration tab sheet (Figure 3) has all the functions to configure the ambient sensor of the device. In the Receive Configuration group box, use the ALSTIM[1:0] drop-down list to set the integration time and resolution for the ALS ADC. The ALSPGA[1:0] drop-down list sets the gain of the ambient light sensing measurement. Use the LUX Thresholds group box to set the upper and lower lux threshold. 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. 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 lux 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 lux threshold and press the adjacent Set button to set the LOTHR register. Use the ALSPST[1:0] drop-down list in the Timer Threshold group box to set the persist value that controls how readily the ambient interrupt logic reacts to a detected event. The Gain Control group box is used to modify the gain of the green channel and the IR channel. Use the TRIM_GAIN_GREEN[6:0] track bar to select the gain trim for the green channel. Use the TRIM_GAIN_IR[8:0] track bar to select the gain trim for the IR channel. Press the Set button to set the TRIM_GAIN_GREEN and TRIM_ GAIN_IR registers. Check the TRIM Enable checkbox to force the part to use the trim value written in the trim gain registers. Status In the Status group box, the Last ALS/PROX Reading group box displays the last set of ambient and proximity ADC data from the graphs on the Data Conversion tab sheet (Figure 1). 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. 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, Read buttons, and Write buttons. The bit names are used to display the current state of each bit (bold 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. __________________________________________________________________ Maxim Integrated Products  6 MAX44000 Evaluation System Evaluates: MAX44000 Figure 2.
