Hallo Hubert,

der Code stammt aus der Bascom-Hilfe

Code:
'name                     : timer0.bas

'copyright                : (c) 1995-2005, MCS Electronics

'purpose                  : shows how to use TIMER0 related statements

'micro                    : 90S2313

'suited for demo          : yes

'commercial addon needed  : no

'-----------------------------------------------------------------------------------------




$regfile = "2313def.dat"                                    ' specify the used micro

$crystal = 8000000                                          ' used crystal frequency

$baud = 19200                                               ' use baud rate

$hwstack = 32                                               ' default use 32 for the hardware stack

$swstack = 10                                               ' default use 10 for the SW stack

$framesize = 40                                             ' default use 40 for the frame space







'First you must configure the timer to operate as a counter or as a timer

'Lets configure it as a COUNTER now

'You must also specify if it will count on a rising or falling edge




Config Timer0 = Counter , Edge = Rising

'Config Timer0 = Counter , Edge = falling

'unremark the line aboven to use timer0 to count on falling edge




'To get/set the value from the timer access the timer/counter register

'lets reset it to 0

Tcnt0 = 0




Do

  Print Tcnt0

Loop Until Tcnt0 >= 10

'when 10 pulses are count the loop is exited

'or use the special variable TIMER0

Timer0 = 0
Irgendwo habe ich inzwischen in der BASCOM-Hilfe gefunden, daß PortB.0 als Inpulseingang für Timer/Counter0 konfiguriert werden kann:

The Port B pins with alternate functions are shown in the following table:

When the pins are used for the alternate function the DDRB and PORTB register has to be set according to the alternate function description.

Port B Pins Alternate Functions

PORTB.0 T0 (Timer/Counter 0 external counter input)


Ist der obengenannte Code jetzt alles was man braucht?
Wird PortB.0 damit automatisch als Pulse-Input für den Counter geschaltet?
