I am not completely clear on Timers, how do I make a timer count 1milisecond as accurately as possible? Have you looked at the Turorials on this site yet? Have you checked the Keil site for examples? Have you checked the chip manufacturer's site for examples? I did, its all for assembler so I am unsure as just how to convert it into C format. for example, lets assume I do:
void delay(long a)
{
long i;
for(i=0;i<a;i++)
{
TL1=18;
TH1=00;
TMOD=0x10;
TR1=1;
while(!TF1);
}
}
with a 24KHz Crystal. will I get 1 milisec delay or will the function take up additional cycles messing up the delay. |
