我使用daq usb-6229與matlab連節時好像有點問題??
首先在matlab command window下
daqwinsoundinfo = daqhwinfo('nidaq')
daqwinsoundinfo =
AdaptorDllName: 'C:\Program Files\MATLAB R2009\toolbox\daq\daq\private\mwnidaqmx.dll'
AdaptorDllVersion: '2.14 (R2009a)'
AdaptorName: 'nidaq'
BoardNames: {'USB-6229' 'PCI-6221'}
InstalledBoardIds: {'Dev2' 'Dev3'}
ObjectConstructorName: {2x3 cell}
這是有抓取到'USB-6229' 和'PCI-6221'
可是我再輸入
ai = analoginput('nidaq','Dev2');
ai
??? Attempt to execute SCRIPT analoginput.analoginput as a function:
C:\Program Files\MATLAB R2009\toolbox\daq\daq\@analoginput\analoginput.m
卻出現以上的結果??
當輸入analogoutput時:
ao = analogoutput('nidaq','Dev2');
ao
Display Summary of Analog Output (AO) Object Using 'USB-6229'.
Output Parameters: 1000 samples per second on each channel.
Trigger Parameters: 1 'Immediate' trigger on START.
Engine status: Waiting for START.
0 total sec. of data currently queued for START.
0 samples currently queued by PUTDATA.
0 samples sent to output device since START.
AO object contains no channels.
那為什麼在input的時候會這樣??
daqmx 8.5.0f3
