My mistakes is up there...
should be like this in NImess.m
taskh1=uint32(1);
[a,b,taskh1] = calllib('myni','DAQmxCreateTask','master',taskh1);
------------------------------------------------------------------------
DAQmx_Val_Volts= 10348; % measure volts
why DAQmx_Val_Volts have this big number?
taskchans1=['Dev1/ai0:' num2str(numofchans-1)];
[a,b,c,d] = calllib('myni','DAQmxCreateAIVoltageChan',uint32(taskh1),taskchans1,'',-1,-10,10,DAQmx_Val_Volts,'')
And what is the order to define the functions parameters:
for example 'DAQmxCreateAIVoltageChan' --> ,uint32(taskh1),taskchans1,'',-1,-10,10,DAQmx_Val_Volts,'' what meens?
How to define my task? 😞
