Nakon gradnje uređaja potrebno je isprogramirati brojeve telefona koje će uređaj zvati prilikom aktivacije senzorskog ulaza.
Nakon programiranja potrebno je dovesti napajanje uređaju. Pritiskom tipke "Pokreni dojavu alarma" započinje zvanje tel. brojeva koji su uprogramirani. Kada se uspostavi poziv, dovoljno je na tastaturi telefona pritisnuti tipku # i uređaj će prestati da zove sve do narednog pritiska tipke za pokretanje dojave.
UPDATE: Source-code (ASM) je dostupan za download!
Umjesto tipke za početak dojave, naravno, poželjno je spojiti neki senzor.
Programiranje brojeva
- pritisnuti program dugme
- podignuti slušalicu na telefonu koji je spojen na istoj liniji
- ukucati prvi broj za poziv, a na kraju njega znak *
- ukucati drugi broj za poziv, a na kraju njega znak *
- ukucati tako brojeva koliko želite, a na kraju završiti sa *# (primjer: 061123123*061456456*#)
Napomena: može biti maksimalno 64 karaktera ukucano u programiranju uključujući znakove * i #.

Stavi promjenljivi otpornik od 100k umjesto tog fiksnog na pin-u 2. Isto to uradi sa otpornikom
od 10k koji je na pin-u 8. Neki od tih otpornika ti ne odgovaraju pa ih moras nastimati.

Pozdrav
Napravio sam ovaj projekt prosle godine i jako sam zahvalan na njemu,sve je radilo kako treba.
Od nekog dana imam problem sta nemogu vise da poništim alarm sa #,te nemogu programirati nove
brojeve (kad stisnem program ledica se upali ali ne treperi kod unosa broja)provao sa
slusalicom na nogu 2 od MT8880 i cuju se DTMF tonovi.
Molio bi za pomoc.
Hvala

I have changed a 10nf capacitor for 100nf one and now is working well. Thank you anyway.

@jfmarque: if it worked on breadboard it should also work on PCB. PCB is OK so you must have
soldered something wrong. Check every component!

Hi Trax
I have done my PCB and put all componentes there. I am facing some issues with random digits.
if I hold a key number MT8880 detect repeted inputs randomly. Like noise or something.. on
bread board this does not happen.
any idea??

Would be nice to have the .hex code for PIC 16F627a. is cheaper than 84A.
Do you have an idea if it is so simple like change some config registers?
I have done .asm file just changing the device on MPLAB and was sucssesfull, but over the
Project did not work.
regards.

Great news! Well, the project works like that. It calls all programmed numbers UNTIL someone
answers and presses the # key. The # key stops alarm from dialing any more numbers. That's the
way every other alarm system work. There is no point in calling other numbers if someone
answered and pressed the # key.

Well. Finally is working. there is something that is not working. I have programmed 2 numbers
but the project only dial the first one.
04555abc....*04555def.....*#. only the first one is dialed. I press # from the third party and
project returns to "waiting for sensor" and never dial the second number. Do you know
why?
By the way. I f I put the 1N4148, does not save the numbers. the signal is too low.

there was a signal improvement using 1-3 and 4-6 (no diodes connected), but led continue ON
after each tone....
Does this project work?? :( I mean... I am doing everything well and I can not see
results...
Led does not turn off after each tone... :(
I am using a 9V baterry with 7805.
