Hello,
I have a NI 9403 DIO card within my DAQ. I am trying to use the write digital lines command to send a pulse whenever I need to (or whenever my code says I need to send a pulse).
The problem I am running into is the time it take between commands (approximately 10ms as the minimum). Here is my code. I pause between the commands for 1ms, but pauses below 10ms just result in a 10ms lag anyways. Preferably I would like to send these commands to my card much faster, but once again, the rate can change fairly often. Any help would be appreciated. Thanks,
DAQmxErrChk(DAQmxCreateTask("", &taskHandle2));
DAQmxErrChk(DAQmxCreateDOChan(taskHandle2, "cDAQ2Mod4/port0/line8:13", "", DAQmx_Val_ChanForAllLines));
DAQmxErrChk(DAQmxStartTask(taskHandle2));
DAQmxErrChk(DAQmxWriteDigitalLines(taskHandle2, 1, 1, 0.0, DAQmx_Val_GroupByChannel, data, NULL, NULL));
std::this_thread::sleep_for(std::chrono::milliseconds(1);
DAQmxErrChk(DAQmxWriteDigitalLines(taskHandle2, 1, 1, 0.0, DAQmx_Val_GroupByChannel, data, NULL, NULL));
