Hello all,I'm currently doing my final year project and I'm in a trouble of programming for this project.I already programmed it using assembly but the problem now here is that my coding for my sensor is not working even though I run it using M-IDE and it said no errors.How can I send sms to the mobile phone when the alarm is triggered?So far,I tested the gsm modem and it's working just fine.....Can anyone kindly guide me for this project?Thanks in advance!

I'm still trying to figure the BZ command that can trigger the alarm....

What chip are you using?
 

Well yes, it throws out a PIC or AVR or any other type of micro. Not all micros use the same commands.
 

I'm using AT89C51...I know I can use PIC but my project stated to use AT89C51.

Does the project also require to use assembly language?

I can't imagine that the shown code does anything useful. Subroutine calls and jumps seems to be mixed up.

You may want to start answering some questions to others and to yourself:
- what is the code expected to do?
- which input signals are processed?
- which output signals are controlled?

Assembly code should have a comment after each line of text that explains what's done there.
Called subroutines should be separated from the "main" code block.
Don't use dubious coding tricks like calling into or jumping out of blocks.


Do you have the option to use C language?
 

I'm sorry if I did not explain myself clear enough.

-My project requires me to use assembly code only.
-I'm required to use AT89C51 so PIC and AVR is out of question.
-So forget about the codes I posted,I rewrite the codes again and it worked so it's fine.
-I have two outputs:The alarm and the sms from the gsm modem.
-I haven't test the gsm modem TOGETHER with the sensor and alarm.
-I'll try to use C language as a back up.
-Does anyone knows how to write the code that can send message from the gsm modem along with the sensor and alarm?
 

Sound like this may be need DLL file , collect template to protocal for communication . Library is required from mobile producer , I think it's hard to decise to corperate company.
So u may use the sms chip, 2 chips form the communication system, that easy way right.
 

I think he needs to send SMS when alarm triggered and he needs a asm code for sending SMS. He has to mention which port alarm is connected. If alarm port is high then SMS has to be sent.
 

Download sample source code from GSM chip ; Ti, Maxim IC, Motololar, ... etc
