I'm working with the GLK 240128-25 and a 4x4 keypad using Microsoft Visual Studio.
I am attempting to use the assign keypad codes decimal format but can't seem to figure out my problem. A sample of my code is below.
I am comfortable communicating with the screen via the serial port. Also when I send the following command below, the screen will lock up and have to be power cycled before I can test the effectiveness of the command. I'm sure I am misunderstanding the manual and would greatly appreciate any help.
Code: Select all
Private Sub Button11_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button11.Click
Dim barray() As Byte = {254, 213, 1, 1}
testport.Open()
testport.Write(barray, 0, barray.Length)
testport.Close()
End Sub
