If there is anyone who needs help on writing program for 8051 based processor, i can write program for your hardware. but you need to specify what actually your program must do. if you feel that your application is much confidential, you can simply give the logic of execution (like port p1.0 goes high 500ms after port 2 receives the byte AA ) of the firmware.
Ive got enough experience on designing systems based on 89C51,89C52,89C54,89C1051,89C2051,89C4051. from a small 3 component board to a complex system with 16 bit ADCs, DACs,Mux, LCDs,Serial EEPROM,EEPROM 128KB etc.

"disassembler for PIC16f84a" in google resulted in 5360 links. check this links
Refer to the link below for the "ASm file for Microcontroller " and the "c code forthe PC".
this is another link. Do give me the schematic and then expect the program.
Yes I got it what you are asking. As people asking like you are more i feel its better i can make a big business by selling custom products. You can search in the google and just make a "ROUGH CIRCUIT"- say a blinking LED when you power up, I hope yours will not need even a General purpose PCB. As you are frm india a bread board of say Rs60/- will do a lot more wonder than you cud dream of. First make a flow chart and specify how many input pins you need. and try to write a program on "YOUR OWN", Ofcourse i can right a program and flash on this forum provided you specified your schematic. Refer the following link. You can start building it. If "all your efforts" are in vain i will make it work for you. Note the lines in double quotes. It is not something like i spoon feed you. Its better you start learning something on your own "Leave no doors UNknocked". If you think i am saying so much philosophy then "GET ME THE SCHEMATIC AND SAY WHAT THE MICROCONTROLLER HAS TO DO" and I will make it work as you expalined. So start building the circuit like the one in this link.
write to me after you had done till this level. Think about adding switches, how many switch and display to inform that it is working in mode 1- alarm.. like that you need leds to inform or 7 sement displays or LCD ?if so bring out and pour your thoughts. As mailing is the only medium for communication you need to explain a lot. Also go through my responses to others. You'll get more if only you ask for it.
Note for ALL :
Please do google before posting here and when you are posting asking for a program give me the schematic and explain what the circuit has to do.I cannot say this repeatedly and it is understood that you will not get reply till you put it clearly. Iam happy to read an essay of explanation for satisfyng your needs.
