/Projects/Phone call alert

After putting together this little device, you must enter programming-mode to learn some phone numbers which this module will call after detecting an input on it's sensor pin.

After programming just supply power to the device. After pressing the button "Pokreni dojavu alarma" it will start to dial (tone or pulse, depending on the jumper setup). When the phone call is succesfully established, the called party should press pound key "#" to stop the device from calling another number or again.

UPDATE: Source code is now available for download!

P1010128

You should put a sensor instead of button "Pokreni dojavu alarma".

Programming the numbers

- press the "program" button
- pick up the phone that is connected to the same phone-line as this device
- punch-in first number and then "*" key
- punch-in then next number and then "*" key
- punch-in the rest of numbers, if more, and finalise with "*#" (example: 061123123*061456456*#)

Please note: The device will learn 64 characters/digits including * and # keys.

Potrebno je isprogramirati ovaj PIC mikrokontroler preko kompjutera - DA.

da li treba ova ic kola programirati, ne programirat brojeve koje ce zvati nego neko dodatno programiranje kao sto je potrebno za neka ic kola preko računala... ?

Ako su u svemu ostalom kompatibilni onda mozes. Ovaj MT8880 ima i neku proceduru inicijalizacije nakon startup-a pa sad treba vidjeti da li to isto zahtjeva i taj tvoj drugi IC...

Trax da li bi ovo radilo ako se zameni MT8880 sa UM95089? Naravno napravio bih novu PCB sa odgovarajućim vezama pinova, jer funkcije pinova nisu na istim pozicijama. 8880 je katastrofa neopravdano skup!

Hi Tony, all those capacitors you mentioned are in nF; 100nF and 10nF. The resistors are 374 kOhm and 4.7 kOhm.
