Tastatur und Lcd funktionieren nicht

[Janigut]

Moin,
Hab gerade mal versucht, Tastatureingaben von einer PS/2-Tastatur auf ein Display auszugeben allerdings kommt das Programm anscheinend nichtmal übers "Config Lcd" hinaus, weil mir absolut garnichts angezeigt wird. Wenn ich nur die ersten Zeilen bis zum "Läuft" in eine neue Datei speicher und Compilier, funktioniert es.
Find ich irgendwie sehr seltsam...
Hatte schonmal jemand das selbe Problem oder kann mir so helfen?

$regfile = "m16def.dat"                                     ' specify the used micro
$crystal = 16000000                                         ' used crystal frequency
'For this example :
'connect PC AT keyboard clock to PINA.2 on the 8535
'connect PC AT keyboard data to PINA.4 on the 8535
'The GetATKBD() function does not use an interrupt.
'But it waits until a key was pressed!
'configure the pins to use for the clock and data
'can be any pin that can serve as an input
'Keydata is the label of the key translation table

Config Keyboard = Pina.2 , Data = Pina.4 , Keydata = Keydata
 Config Lcd = 16 * 2
 Config Lcdpin = Pin , Db4 = Portd.0 , Db5 = Portd.1 , Db6 = Portd.2 , Db7 = Portd.3 , E = Portd.5 , Rs = Portd.4
 Config Lcdbus = 4
 Cursor Off , Noblink

Cls
Locate 1 , 1
Lcd "Laeuft"

'Dim some used variables


Dim S As String * 12

Dim B As Byte


'In this example we use SERIAL(COM) INPUT redirection

$serialinput = Kbdinput



'Show the program is running




Do

'The following code is remarked but show how to use the GetATKBD() function
' B = Getatkbd()     'get a byte and store it into byte variable
'When no real key is pressed the result is 0
'So test if the result was > 0
' If B > 0 Then
'    Print B ; Chr(b)
' End If



'The purpose of this sample was how to use a PC AT keyboard
'The input that normally comes from the serial port is redirected to the
'external keyboard so you use it to type

Input "Name " , S

'and show the result

Cls
Locate 1 , 1
Lcd S
'Print S

'now wait for the F1 key , we defined the number 200 for F1 in the table

Do

  B = Getatkbd()

Loop Until B <> 0

Cls
Locate 2 , 1
Lcd B

Loop

End



'Since we do a redirection we call the routine from the redirection routine

'

Kbdinput:

'we come here when input is required from the COM port

'So we pass the key into R24 with the GetATkbd function

' We need some ASM code to save the registers used by the function

$asm

push r16           ; save used register

push r25

push r26

push r27



Kbdinput1:

rCall _getatkbd   ; call the function

tst r24           ; check for zero

breq Kbdinput1     ; yes so try again

pop r27           ; we got a valid key so restore registers

pop r26

pop r25

pop r16

$end Asm

'just return

Return



'The tricky part is that you MUST include a normal call to the routine

'otherwise you get an error

'This is no clean solution and will be changed

B = Getatkbd()



'This is the key translation table

Hallo Janigut,
da ist eine Sache, die ich mir vorstellen könnte.
Du benutzt die Umleitung für das Input Kommando, welches normalerweise Daten vom UART liest. Dabei würden die Pins D.0 und D.1 automatisch eine andere Funktion bekommen und nicht mehr als GPIO benutzbar sein.
Es könnte sein, dass die Pin Umschaltung trotz des $serialinput rein kompiliert wurde und damit würde dein LCD nicht mehr funktionieren.
Ich würde mal andere Pins für D.0 und D.1 nehmen.
