HOW IS ALARM SYSTEM PROGRAMMED USING 8051 MICRO-CONTROLLER?
It will be down to how YOU want to write it! There are various high-level programming language compilers for the 8051. Several C compilers are available for the 8051, most of which feature extensions that allow the programmer to specify where each variable should be stored in its six types of memory, and provide access to 8051 specific hardware features such as the multiple register banks and bit manipulation instructions. There are many commercial C compilers. SDCC is a popular open source C compiler. Other high level languages such as Forth, BASIC, Pascal/Object Pascal, PL/M and Modula-2 are available for the 8051, but they are less widely used than C and assembly.
