How can I get multi channel reads using the NIDAQ library

[DaleFlow]

Hi
 
USB 6008. Python
Can anyone tell me how I can read three channels simultaneously?
I tried "Dev/ai0:2" but this did not work. Using just Dev1/ai0 gives the correct result but I need this for 3 channels (simultaneuosly)
 
Thanks
       
# now, on with the program        CHK(nidaq.DAQmxCreateTask("",ctypes.byref(taskHandle)))        CHK(nidaq.DAQmxCreateAIVoltageChan(taskHandle,"Dev1/ai0","",                                           DAQmx_Val_Diff,                                  #DAQmx_Val_Diff,   #DAQmx_Val_RSE,       #DAQmx_Val_Cfg_Default,                                           float64(-10.0),float64(10.0),                                           DAQmx_Val_Volts,None))        CHK(nidaq.DAQmxCfgSampClkTiming(taskHandle,"",float64(10000.0),                                        DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,                                        uInt64(max_num_samples)));        CHK(nidaq.DAQmxStartTask(taskHandle))        read = int32()        CHK(nidaq.DAQmxReadAnalogF64(taskHandle,max_num_samples,float64(1.0),                                     DAQmx_Val_GroupByChannel,data.ctypes.data,                                     max_num_samples,ctypes.byref(read),None))

Hi Jochen

Thanks. I figured out the solution myself. I posted that solution for others :-)
