Hey bungee, yeah I've tried changing that. But I found something that might help. Each of the two values has a count difference of about 2650 counts. Regardless of how far away I stand.

I think I m ...

If you need a delay, why not using the CCS built-in delay_XX() functions? They are achieving exact delays, considering the clock settings.

why does the maximum value for X have to be 65535?
It doe ...

Hey, if i have a for loop, and I need to put in a delay,

so like for(counter=0; counter < X ; counter ++){ do whatever}

why does the maximum value for X have to be 65535? And apart from chan ...

Hey bungee, thanks for your help. Just one last question,

If I put the enable_interupts(ccp1) command in my program, does that start looking for the high in that pin from that point onwards only? E ...

Yes! I think it works! Well at least I think it does. For some reason, I'm getting values that are closer to what I need. I just hope I haven't hacked it.

This is what I got in the end, I've stripp ...

You are on the right path. Basically you need to setup timer once and then just set it to 0 on start and read the value on end. Maybe your timer overflows in a second measurement. Create simple timer ...

Cool thanks. I ended up going for the second option cause it pretty much acts like a time-out loop in itself. However, I'm getting heaps of erratic 'values'. The values are meant to be the number of ...

Hey, just a quick question regarding timers.

If I use a 4Mhz system clock, and use the following,
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_16);

I am essentially telling the timer to c ...

Currently, one of us suggests a few changes and you implement them. Then you re-post the code and ask us to look at it again, without you
doing anything at all. Why don't you try to fix the proble ...

Hey PCM, I ran the code but it has the following problems. I'm still trying to debug it, so any advice would be useful.

When I run it, I get 'PINC5 did not go HIGH, Error' repeatedly. And it comes ...

You can use the similar code I wrote. You will just change first ISR so
that you'll run it inside main program loop. And the other part could stay
almost the same (throw out the EXT interrupt pa ...

hey tlmah,

thanks so much. i know the mistake i was makin. it works now

thanks again

Hey all,

I have a quick question regarding hyper terminal. To be honest, I'm using windows XP so its actually terminal.exe. I have written a program in my PIC16F690 that sends in some data periodic ...

One obvious suggestion. Use a set/reset latch.
Connect the first signal to the 'set' pin, and the second the the 'reset' pin. Then feed the output to the single CCP. The pulse width is what you want. ...

Are you trying to determine range by comparing time of flight of a radio signal and an ultrasonic signal? If so can you consider the radio signal as instantaneous and just measure the time of the ult ...
