Figure 1. MAX11040 Evaluation Kit Main Window 6 _______________________________________________________________________________________ MAX11040 Evaluation Kit/Daughterboard The MAX11040 EV kit’s main window is shown in Figure 1. The Setup group box, located at the top of the window, contains Configuration, Sampling Instant Control, and Output Data Rate Control group boxes. Functions related to reading single-sample ADC values in the ADC Conversion group box are located in the middle section. Data-logging functions and data calculation are in the Data Logging group box, located at the bottom of the main window. Up to five devices can be cascaded by using the daughterboards. Select the number of cascaded ICs from the Number of Devices menu item. Setup All the settings in the Setup group box correspond to the registers of the IC specified in the IC Selection drop-down list. In the IC Selection drop-down list, MAX11040 IC #1 and MAX11040 IC #2 represent the ICs (U1 and U2) on the EV kit. MAX11040 IC #3, MAX11040 IC #4, and MAX11040 IC #5 represent the ICs on the optionally cascaded daughterboards. When the EV kit software starts up, or when a different IC is selected in the IC Selection drop-down list, the Configuration, Sampling Instant Control, and Output Data Rate Control group boxes display the content of the IC specified in the IC Selection drop-down list. Configuration In the Configuration group box, the user can change the value of the configuration register in the selected IC. Each checkbox in the Configuration group box corresponds to a bit in the configuration register. Click on the checkbox to toggle each bit. Sampling Instant Control Adjust the appropriate scrollbars in the Sampling Instant Control group box to set the sampling instant delay for the input channels. Output Data Rate Control There are three panels in the Output Data Rate Control group box, and each one of them has a different way to set up the data rate of the IC. The user can select one of them by checking the corresponding radio button on the left of the panel. To set the sample rate by directly controlling the ADC’s register (coarse adjust and fine adjust), use the first panel at the top of the Output Data Rate Control group box. Select the coarse-adjusted output-data rate in the Coarse Adjust drop-down list, and adjust the Fine Adjust scrollbar to set up the output data rate. The Coarse Adjust drop-down list and the Fine Adjust scrollbar correspond to the output data rate coarse adjust register and the output data rate fine adjust register, respectively. The actual data rate is displayed in the Actual Data Rate label. To set the sample rate by entering a desired sample rate, and letting the EV kit software calculate the closest possible sample rate, use the Request Data Rate edit box. Enter the desired data rate into the Request Data Rate edit box and press the enter key. The program sets up the closest possible data rate automatically. The actual data rate is displayed in the Actual Data Rate label. To set the sample rate by letting the software detect the input frequency, and adjust the sample rate to a desired number of samples per cycle, use the Auto Adjust Sample Rate group box. The software detects the frequency of the input signal on any channel selected in the drop-down list. Set up the data rate based on how many samples per input-signal cycle was requested in the Samples/Cycle edit box. The actual data rate is displayed in the Actual Data Rate label. ADC Conversion The ADC Value Display group box, shown in the ADC Conversion group box, displays the output data codes and the calculated voltage values for a single sample of all of the channels on the IC specified in the IC Selection drop-down list. Pressing the Convert button in the ADC Conversion group box updates the status of the ADC Value Display group box. Check the Auto Convert checkbox to automatically and repeatedly read the current ADC value at a rate set by the Time Interval drop-down list. Data Logging Start Conversion The Data Logging group box is located at the bottom of the window. The user can select the desired number of conversions in the Number of Samples drop-down list. Press the Start Conversion button in the Data Logging group box to start sampling at the rate that was set by the Output Data Rate Control group box. Output File Data The Save to File button is not active until the sampling is done. After sampling is finished, and before pressing _______________________________________________________________________________________ 7 Evaluate: MAX11040 Detailed Description of Software Evaluate: MAX11040 MAX11040 Evaluation Kit/Daughterboard the Save to File button, the user needs to select in the Output File Data group box which channels will have their sampled data saved into the file. The software keeps a record of channel selections for each IC. Select the IC you wish to select in the IC Selection drop-down list, to display and allow modification of channel selection for that IC. Press the Select All Channels on All ICs button to check all the checkboxes in the Output File Data group box for all ICs. Press the Deselect All Channels on All ICs button to clear all the checkboxes in the Output File Data group box. Press the Save to File button to save the data from the selected channels into a file. Zero-Crossing Alignment Option In the Option group box, when the Align to Zero Crossing Point checkbox is checked, the program detects the rising zero-crossing point in the sampled data of the channel specified in the IC Selection and Channel Selection drop-down lists. When the Save to File button is pressed, the program saves the sampled data starting from the rising zero-crossing point. Calculation After sampling is finished, press the Calculate button to calculate the Frequency, RMS, MIN, MAX, and Avg DC of the input signal of the channel specified in the IC Selection and Channel Selection drop-down lists. The calculation for Frequency uses a simple algorithm that has limitations. The Frequency is calculated by measuring the time between two rising zero-crossing points. An error may show up in circumstances where DC offset is on the order of the input-signal amplitude, or if there is significant noise or other frequency content in the signal that creates multiple zero crossings near the fundamental crossing. To calculate these results for a different channel, change the IC Selection and Channel Selection drop-down list, and press the Calculate button. Clear LED When any of the LEDs on the EV kit and the daughterboard are on, press the Clear LED button to turn off the LEDs after the overflow and the overvoltage faults are cleared. Sync Pulse Press the Sync Pulse button to synchronize the output data timing for all cascaded devices. 8 Detailed Description of Hardware MAX11040 EV Kit The MAX11040 EV kit board provides a proven layout for evaluating the IC’s four-channel, simultaneous-sampling ADC.
