evaluate: max11040 max11040 evaluation kit/daughterboard _______________________________________________________________________________________ 7 detailed description of software the max11040 ev kit? main window is shown in figure1. the setup group box, located at the top of the win- dow, contains configuration , sampling instant control , and output data rate control group boxes. functions related to reading single-sample adc valuesin the adc conversion group box are located in the middle section. data-logging functions and data calcu-lation 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 corre- sponds to a bit in the configuration register. click onthe 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 differ- ent way to set up the data rate of the ic. the user canselect 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? 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 ratein 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 coarseadjust register and the output data rate fine adjust reg- ister, respectively. the actual data rate is displayed in the actual data rate label. to set the sample rate by entering a desired samplerate, and letting the ev kit software calculate the clos- est 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 pro- gram sets up the closest possible data rate automati-cally. the actual data rate is displayed in the actual data rate label. to set the sample rate by letting the software detect theinput 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 select-ed in the drop-down list. set up the data rate based on how many samples per input-signal cycle was request- ed 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 setby 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 numberof 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 downloaded from: http:///
