bascom timer

hello everyone!
can i generate a reliable frequency using waitus command in bascom avr?
thanx.

please answer me!
thanks
 

bascom pulseout


hi
I dont expect bascom to make an accurate frequency as the basic commands time is unknown( the assembly only can be calculated), also it may differ greatly if the crystal is not right configured,that's the command
$crystal=4000000 ( as an example)

bascom and generate pulse and timer


hi
the timers can be used as timers , counters or pwm
the prescale is the factor that divide the crystal to slow down the timer
capture edge is ude with counters ( falling or rising)
timer 0 is 8 bits , the 2 other are 16bit

go to bascom help for example programs

bascom timer

see bascom help for "PULSE" command

Generates a pulse on a pin of a PORT of specified period in 1uS units for 4 MHz.

Syntax
PULSEOUT PORT , PIN , PERIOD


Remarks

PORT Name of the PORT. PORTB for example
PIN Variable or constant with the pin number (0-7).
PERIOD Number of periods the pulse will last. The periods are in uS when an XTAL of 4 MHz is used.
The pulse is generated by toggling the pin twice, thus the initial state of the pin determines the polarity.
The PIN must be configured as an output pin before this statement can be used.


also look at the "SOUND" command
