我是一名新手,正在編寫自動啤酒廠中的代碼,並將其重寫爲從模擬溫度感測轉換爲單線。OneWire DS18B20從指定的傳感器獲取vb.net中的溫度
但是,我正在努力獲得任何喜悅,有人可以運行他們的大腦在這段代碼對我和建議請嗎?目標是讓HLT_currenttemp讀取hltaddress處DS18B20傳感器的當前溫度。
Dim owd As com.dalsemi.onewire.container.OneWireContainer
Dim state As Object
Dim tc As com.dalsemi.onewire.container.TemperatureContainer
' Try
' get exclusive use of 1-Wire network
adapter.beginExclusive(True)
' clear any previous search restrictions
adapter.setSearchAllDevices()
adapter.targetAllFamilies()
adapter.setSpeed(com.dalsemi.onewire.adapter.DSPortAdapter.SPEED_REGULAR)
owd = CreateObject("OWAPI.OneWireContainer28")
' retrieve OneWireContainer
owd.setupContainer(adapter, hltaddress)
' cast the OneWireContainer to TemperatureContainer
tc = DirectCast(owd, com.dalsemi.onewire.container.TemperatureContainer)
' read the device
state = tc.readDevice
' extract the temperature from previous read
tc.doTemperatureConvert(state)
' retrieve Temp
HLT_Currentemp = (Math.Round(tc.getTemperature(state), 2))
Debug.WriteLine(tc.getTemperature(state))
' end exclusive use of 1-Wire net adapter
adapter.endExclusive()
'Catch ex As Exception
Debug.WriteLine(hltaddress)
' End Try
