hi everyone;
I'm using PIC16F877A to count pulses on T1ck in a specific period to get the rate of these pulses in minute (PPM) but it don't act as i expect and i don't know where is the error ?:(
so can anyone help me ?
here is my code (i MicroC):
// LCD module connections
sbit LCD_RS at...
just try this:
void main() {
trisb=0;
portb=0;
while(1){
portb=0b11111111;
delay_ms(50);
portb=0;
delay_ms(50);
}
}
=====================================
also your code will work good but if you use any simulation software you should reduce delay time as simulators has a different calculations...
yes like axxe say
as without this delay the transition from 0 to 1 on portb will happen but you will not be able to see it as it is very fast.
as in your code the MC will do 1 sec OFF and xx usec (xx depend on your OSC ) ON then it convert to OFF and so on.
hi
u can see this, i think it may help

this is an Example:

you can get them from here
thanks pmar_kpj for help
the program now run very well.
but if i want to increase the period at which the pulse-width change since i press the increase button, i.e. when i press pushbutton the pulse width become full after short time so if i want to increase this time i have to increase delay...
hi every one
=============
I wrote this program sothat i can change pulse-width but i think there is an error as it doesn't work as it should.
i'm using Microc pro Compiler .
so can anyone help me.
===================================
here is the code:
sbit speed_I at RB0_bit;
sbit speed_D at...
