Thanks Mike, I will take a look at that timing gate example...
I haven't tested yet the circuit on a scope but I have made some modifications on the code.
As far as I understand, the CCP1 value is ...

So, your frequency meter reads ~60kHz.

Where is the problem?

(1) Is the oscillator running at ~60kHz, and the meter reading ~60kHz?
(2) Is the oscillator running at your expected ~400kHz and th ...

This version of the code will accept a 1 MHz input. The displayed
frequency resolution is +/- 0.6 %. You will not get 1000001 Hz or
1000002 Hz, etc., with this program. It's more like 1000000 ...

Thank you for your answers. I apologize for the length of the post but I didn't knew exactly what can cause the interrupt problems. Now everything is clear and I will modify the code according to your ...

Hello.
I'm trying to make an app for controlling a door. I use a PIC16F876A, a 4x3 keyboard and a 16x1 LCD.
I have tested the circuit but I can't get the serial interrupt working. The serial connec ...

Hello.
I have a question regarding this tutorial.
In this case:
void main() {
int i;
setup_timer_0(RTCC_INTERNAL|RTTC_8_BIT|RTCC_DIV_4);

Hi,

At the risk of offending you, a simple question, have you got pull up resistors on SDA, SCL?

Hi. You are not offending me Very Happy

I'm a beginner and I accept any advices. The answ ...

Hello.
I have some problems in driving a dc motor with a PIC16F876 and
#include <16F876.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit ...

I didn't knew that:)
Thanks alot.

Hello.

I'm trying to make a simple program to write the state of portA pins to a lcd.
#include <16F876.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#include < ...

Is it possible to control 2 serial lines with a pic16f876? (one serial for PC and one serial for another pic16f876) ... or in other words, to have multiple Rx/Tx pins.

I would like to have somethin ...

Thats cool. Thanks:)

I'm still interested in reading those bits.

Hello.
I'm beginner with PIC and ccs. I need some help/advices in reading data from a multiplexer.
I'm using a PIC16f876 for reading 9 digital inputs. Initially I've set portB (all 8 pins) and pin ...

Hello.
I'm trying to make a program for a pic16f876 connected via rs232 with a Gumstix microcomputer. The PIC mc is reading from RB0 (input pin) the data transmitted by an optical transducer and tran ...
