hello,
I managed to use jamod (connections with WAGO plc) with Eclipse Android
I want to create a library for B4A
everything works fine but when compiling I get an error launching the application.
do you have an idea or this bug.
thank you
my code b4a
'Activity module
Sub Process_Globals
'These global variables will be declared once when the application starts.
'These variables can be accessed from all modules.
Dim port_num As Int
Dim adr_ip As Double
Dim val_bit As Boolean
Dim my_wago As MODBUS_TCP_MASTER_B4A
End Sub
Sub Globals
'These global variables will be redeclared each time the activity is created.
'These variables can only be accessed from this module.
Dim button1 As Button
Dim label1 As Label
End Sub
Sub Activity_Create(FirstTime As Boolean)
If FirstTime Then
Activity.LoadLayout("1")
my_wago.Ip("192.168.2.150")
my_wago.Connection
End If
End Sub
Sub Activity_Resume
End Sub
Sub Activity_Pause (UserClosed As Boolean)
End Sub
Sub Button1_Click
Dim x As String
x=my_wago.ReadInput(0,2)
label1.Text=x
