I was wondering if anybody knows of anyplace that actually shows what all of the values that you put into the c-code mean? As an example, I want to use this function: DAQmxErrChk (DAQmxCreateCISemiPeriodChan(taskHandle_0,"Dev1/ctr0","",0.000000100,100.838860750,DAQmx_Val_Seconds,"")); I understand most of what is going on here, but I'm not sure what these #,s are ^ ^ Is there a place where I can find a list of these C functions with all of the arguments? Or a book would be great too. Thanks for you help. Craig
