ISP Speed Test
Thursday, June 28th, 2007

I was unable to start the application on my laptop running XP SP2. I opened a bug report for KC with a screen shots of the error. I plan to try again on a different machine.
The error appeared to be related to a font issue…

Dim LCD As New oLCD
Dim x As New oByte
Sub Main()
LCD.IOLineRS = 24 ’ Set up the I/O.
LCD.IOLineE = 17
LCD.IOGroup = 3
LCD.Nibble = 1
LCD.Operate = 1 ’ Turn on the oLCD Object.
LCD.Init ’ Initialize the LCD Module.
LCD.Clear ’ Clear the screen.
LCD.Locate(0,0)
LCD.String = “ StempleLABS 2006″
Do
For x.Value = 1 To 21
LCD.Locate(1,x.Value)
LCD.Value = 255
ooPIC.Delay = 5
LCD.Locate(1,x.Value - 2)
LCD.Value = 254
Next x.Value
For x.Value = 1 To 21
LCD.Locate(1,20 - x.Value)
LCD.Value = 255
ooPIC.Delay = 5
LCD.Locate(1,20 - x.Value + 2)
LCD.Value = 254
Next x.Value
Loop
End Sub
I currently have 10 bi-color 5×7 LED Matrix packages that were picked at a sale.
Found this NUTs and Volts story about driving this package use scanning.
