hi,

es gab ja doch ab und zu mal ein paar Fragen nach der Ansteuerung für den ADNS2610 mit BASCOM.
Ich hab mich die Tage mal dran gemacht und das realisiert.

Anschluss ist der übliche, steht auch im DB des Chips.

Code:
Code:
$regfile = "m8def.dat"
$crystal = 16000000
$baud = 19200

Ddr_sck Alias Ddrd.6
Ddr_sdio Alias Ddrd.7

Port_sck Alias Portd.6
Port_sdio Alias Portd.7
Pin_sdio Alias Pind.7

Declare Sub Adns2610_init()
Declare Sub Adns2610_write_byte(byval Write_byte As Byte)
Declare Function Adns2610_read_byte() As Byte
Declare Sub Adns2610_write_operation(byval Address_byte As Byte , Byval Data_byte As Byte)
Declare Function Adns2610_read_operation(byval Address_byte As Byte) As Byte

Call Adns2610_init()

Dim X As Integer
Dim Y As Integer

X = 0
Y = 0

Dim X_cm As Single
Dim Y_cm As Single

Dim Read_data As Byte

Read_data = 0

Dim Tmp As Byte

Tmp = 0



Do


   Read_data = Adns2610_read_operation(&H03)

   If Read_data > &H7F Then

      Tmp = &HFF - Read_data

      Incr Tmp

      X = X - Tmp

   Else

      X = X + Read_data

   End If

   X_cm = X * 0.00635

   Print " X: " ; X_cm;



   Read_data = Adns2610_read_operation(&H02)

   If Read_data > &H7F Then

      Tmp = &HFF - Read_data

      Incr Tmp

      Y = Y - Tmp

   Else

      Y = Y + Read_data

   End If

   Y_cm = Y * 0.00635

   Print " Y: " ; Y_cm;

End

   Ddr_sdio = 1

   For I = 7 To 0 Step -1

      Port_sck = 0

      Port_sdio = Write_byte.i

      Waitus 1

      Port_sck = 1

      Waitus 1

   Next I

   Ddr_sdio = 0
   Port_sdio = 0

End Sub

Function Adns2610_read_byte() As Byte

   Local I As Byte

   Local Data_byte As Byte

   Waitus 250

   For I = 7 To 0 Step -1

      Port_sck = 0

      Waitus 1

      Port_sck = 1

      Data_byte.i = Pin_sdio

   Next I

   Adns2610_read_byte = Data_byte

End Function

Sub Adns2610_write_operation(byval Address_byte As Byte , Byval Data_byte As Byte)

   Address_byte = Address_byte Or &B10000000

   Call Adns2610_write_byte(address_byte)
   Call Adns2610_write_byte(data_byte)

End Sub

   Call Adns2610_write_byte(address_byte)

   Adns2610_read_operation = Adns2610_read_byte()

End Function
Vllt. kann der ein oder andere damit was anfangen. Ich stell ihn auch noch gleich ins Wiki dazu. zu dem PAN Bsp in C.

/Edit Ich seh grad, dass man da angemeldet sein muss....Ich muss jetzt los. Das mit dem Wiki schau ich mir die Tage an, oder einer von euch ist so nett, und machts da rein.
