Hi
I am experiencing some difficulties in trying to get the TIMER1 to run in my interrupt routine.
In my interrupt routine, it has a password input module that waits for the input of the password in a for loop. During that time, I am suppose to set a time-limit for the input before sending off...
Hi,
I am working with a iTegno 3800 GSM modem and I require to wake the PIC out of sleep mode and retrieve the data in the SMS whenever I receive it. The programming language i am using is C.
What are the possible ways I could do this? I was thinking of EUSART Receive Interrupt bits but I am...
Thanks for the tips,
I had changed the code to wake up from sleep through a INT input.
However, the interrupt only runs once, with or without sleep.
Can anyone help me with this problem?
#include <p18f4520.h>
#include <stdlib.h>
#include <delays.h>
void InterruptHandlerLow(void);

Hello,
I am working on a Anti-House Breaking System project which operates 24 hour/day surveillance.
I am planning to put it on sleep mode until the PIR sensor or Glass-Break sensor detects a break-in. How can this be done? (if possible)
I am aware of the 7 different operating modes but...
Thanks for the help.
My aim is to get a logic "1" when the sensor detects a glass break for microcontroller program to trigger a series of events.
I have connected
+ to Vcc
- to Ground.
Where should I connect the rest of the pins to?
Hi
I am working on a anti house breaking system project and i just purchased a glass breaking sensor. However, I am not sure how to configure the pins of the glass breaking sensor.
It has +, -, Relay NC, RelayCOM and 2 anti-tamper output pins.
Here is the datasheet.
**broken link removed**

Piezo Transducer
I am trying to stimulate a glass breaking sensor by using a Piezo Transducer to P18F4520.
Can any type of piezo transducer be used or do I have to find a specific piezo transducer to be compatible with the sound of breaking glass?
Thanks
