添加MSComm和Timer控件MSComm1 、Timer1
Private Sub Form_Load()
If Not MSComm1.PortOpen Then
MSComm1.CommPort = 1 '假如您的串口是 COM1
MSComm1.InputMode = comInputModeBinary
MSComm1.Settings = "9600,N,8,1"
MSComm1.EOFEnable = False
MSComm1.Handshaking = comNone
MSComm1.PortOpen = True
End If
Timer1.Interval = 50
End Sub
Private Sub Timer1_Timer()
DIM Dax AS Byte
Dax = 你想输出的字节数据(&H00-&HFF)
MSComm1.Output =Dax
End Sub
Private Sub Form_Load()
If Not MSComm1.PortOpen Then
MSComm1.CommPort = 1 '假如您的串口是 COM1
MSComm1.InputMode = comInputModeBinary
MSComm1.Settings = "9600,N,8,1"
MSComm1.EOFEnable = False
MSComm1.Handshaking = comNone
MSComm1.PortOpen = True
End If
Timer1.Interval = 50
End Sub
Private Sub Timer1_Timer()
DIM Dax AS Byte
Dax = 你想输出的字节数据(&H00-&HFF)
