[問題] 關於advantech擷取卡與matlab的一些問題已回收
首先感謝先前問類似問題時,zzs大和wave大大熱心解答，我後來有找到
instrument tool box
我後來把驅動程式重新安裝之後，輸入指令>>ans.InstalledAdaptors
結果出現???Reference to non-existent field'InstalledAdaptors'
先前還沒有把驅動重新安裝時會出現'advantech',請問這是沒有讀到這張卡的意思嗎?
後來我又試了一個指令>>ai=analog('advantech','0')
結果如下
Display Summary of Analog Input (AI) Object Using 'PCI-1712 (Device 0)'.
Acquisition Parameters: 1000 samples per second on each channel.
1000 samples per trigger on each channel.
1 sec. of data to be logged upon START.
Log data to 'Memory' on trigger.
Trigger Parameters: 1 'Immediate' trigger(s) on START.
Engine status: Waiting for START.
0 samples acquired since starting.
0 samples available for GETDATA.
AI object contains no channels.
這樣是有找到這張卡的意思嗎???
我又輸入了指令>>daqhwinfo(ai)
結果如下
AdaptorName: 'advantech'
Bits: 12
Coupling: {'DC Coupled'}
DeviceName: 'PCI-1712 (Device 0)'
DifferentialIDs: []
Gains: [0.5000 1 2 4 8]
ID: '0'
InputRanges: [9x2 double]
MaxSampleRate: 1000000
MinSampleRate: 154
NativeDataType: 'uint16'
Polarity: {'Unipolar' 'Bipolar'}
SampleType: 'Scanning'
SingleEndedIDs: [0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15]
SubsystemType: 'AnalogInput'
TotalChannels: 16
VendorDriverDescription: 'ads1712.dll'
VendorDriverVersion: 'Ver 1.0'
為什麼剛才上一個指令Acquisition Parameters: 1000 samples per second on each channel.
1000 samples per trigger on each channel.
取樣頻率只能1000
我的卡片不是可以到1M 的取樣數嗎???
請知道的大大煩請幫我解答一下,謝謝!
