thank you so much PCM programmer!

i wish you could be my mentor!

what i initially thought was that ir_value1 was being compared to 4 volts... stupid me... i wasnt thinking 4 in binary

please dont tell me this is because i'm trying to compare a 8 bit number against a number 4 which is almost true even when its close to 0

and so 4 volts would be like 200 instead of just 4

hmmm yeah theres an error there,

i've changed it to this:

while (true)
{

forward();
output_low(PIN_B7);
ir_value1=read_adc();
...

I'm having trouble with the ADC.. I've read all the previous posts about it and tried their solutions but I can't get it to work..

Heres my code:

#include <18F452.h>
#device ADC=8;
#fu ...

I'm trying to use both CCP1 and CCP2

Do they use the same timer (timer2)? I have tried to set it up, but it keeps freezing on start up. I'm using a PIC18F452

How to declare interrupt bits in CCS? (in general)

like for the TMR2IF (timer 2 interrupt flag) it is:

#bit TMR2IF=0xF9E.1

what does that actually mean?

On the PIC18F452 datasheet, it says ...

any idea what's wrong?

this is SO strange.

Now it's not working?

Does anyone know? Desperately seeking an answer

(the problem is that the motor isn't running continuously)

and so i figured out the problem (after 2 weeks of gutwrentching testing). It was the code!

it should've been while(TMR2IF=0); rather than ==

:(

#bit TMR2IF=0xF9E.1

TMR2IF=0;
while (TRUE) {
while (TMR2IF==0) ;
TMR2IF==0;
set_pwm1_duty(120);
}

Just wondering, should that be TMR2IF=0; ...

hey! thanks for the tips. I'll try them out.

My goal for the interrupt is to satisfy this:

When the motor is running, a sensor senses a pylon, and then the sensor interrupt will switch the moto ...

I hope this is not asking too much, but how would you implement an interrupt to your above code?

Thank you so mucH!!!

I'm using a TIP31 NPN transistor
I'll try a mosfet

I changed that little bit and it still does the same thing, but then i hooked an LED onto that pin and it's constantly on, so the problem (i think) is the transistor im using to switch the motor on an ...

thank you very much! your help is very much appreciated!
