Im totally a fresh newbie in PIC and i also never learn PIC before, i hope all the forumers here can help me and let me know wat should i do 1st.... Thanx!!!!!

I now doing for my degree final year project. The project is need to design a telephone control automations and security system which is control by PIC microchip.

The instruction for the system is, When the user is calling the house phone, after about 20sec nobody to answer the phone, it will directly go to system and the user is need to key in the password to access to the system. After password verify, the user can choose the options from the menu, Example like:

Press 1 is access to the security system,
Press 2 to access to home automation system(Controlling Lightning or fans system), and
Press 0 to disable/enable the alarm system


After the selection, the user can directly press the number represented to turn on or off the system or automation parts.

When the alarm is triggled, the system will automatically call the user and alert to user which part of the system is triggled by listenning tone type generated by tone generator.

For the whole system connection, we using RF wireless connection system. And the automation part and security part, we dividedboth into 4 zones.

My questions is here...
1. Can i use the 16f877 for my project?? or other model of PIC is more suitable??
2. Is is need other PIC to control the auto dialer part????
3. Any recommended website to referring??
4. Can i build any Development board or tester board by myself??? cos i got budget for my project.
5. Does my system can be done like the command optionals i wrote??

Thanks for helping me.... ur reply i will be appreciated.....
 

Re: Design phone control automations and security system By

Are you doing ur project alone?

My suggestion is

1.split the project into few modules

2.Determine the specification for each module

eg: Wat software needed, assembly or C programming, tyoe of interfacing ....

afterward, you can find many information at this forum. Please search for it.

Hope this can help.

regards,
Michael
 

Design phone control automations and security system By PIC

this project is doing by 4 group members,
i in charge for programming part.
But i very fresh in PIC programming, so need the comments from forumers....

If your project is complex.... i would recomend the 18f452//18f458, he can be programed in C18 and if you want to program in assembler, the intruction set is more powerfull[/quote]
 

hi....All friends here...

i use the MPLAB V7.0 to complier my program.
but got the error of
"Source file path exceeds 62 characters.
Halting build on first failure as requested."
Wat meaning of this error??? is it limit my length of program??

Got other PIC assembler recommend to use????

thanx!!!!
 

Change the directory path less than 62 characters. for example
c:program file/my proyect/proyect.mcp = 37 characteres
 

Hi....

I just got my DTMF decoder Output signal.....
The output from DTMF is in Binary code....
which mean that, the number "1" is press, then it will generate 0001 binary code.

My questions is here...
Can the PIC understand the binary code generated from DTMF???? Or i need to convert the binary to High/Low state???
 

you will have to connect the DTMF decoder to the PIC pins. Then you can input the port status. This is not very difficult. Also you can look at google, their exist plenty designs with DTMF decoder chips, maybe also with yours.
