Hi,
i have problems to write a little bit more dat to a nextion-Display.
At first i mean there is a problem with the Display or my code, so i have spend a lot of time
to change and try something. -- No success
So i have write this little test code
this workes fine,
but when i duplicate the 4 lines (Stream2.write) in the timer event the application hangs
the same when:
- i make delays between the two blocks
- or make the timer.interval higher (10 sec)
it is not possible to transfer 8 lines

Sub Process_Globals
'These global variables will be declared once when the application starts.
'Public variables can be accessed from all modules.
Public Serial1 As Serial
Private Stream2 As AsyncStreams
Private SerialNative2 As Stream
Private timer1 As Timer
Private x As Int = 1
End Sub
Private Sub AppStart
Serial1.Initialize(115200)
Log("AppStart")
' Display
RunNative("SerialNative2",Null)
Stream2.Initialize(SerialNative2, "Stream2_newdata", Null)
timer1.Initialize("T1_action",100)
timer1.Enabled = True
End Sub
Sub t1_action
Log("Timer:",NumberFormat(x,0,0))
x = x+1
Stream2.Write("page 2").Write(Array As Byte(0xFF, 0xFF, 0xFF))
Stream2.Write("stunde.txt=").Write(QUOTE).Write(NumberFormat(x,0,2)).Write(QUOTE).Write(Array As Byte(0xFF, 0xFF, 0xFF))
Stream2.Write("t11.txt=").Write(QUOTE).Write(NumberFormat(x,0,2)).Write(QUOTE).Write(Array As Byte(0xFF, 0xFF, 0xFF))
Stream2.Write("j0.val=").Write(NumberFormat(x,0,0)).Write(Array As Byte(0xFF, 0xFF, 0xFF))
