C programming for embedded system applications
• Retained for use throughout the program in RAM locations that are not reallocated during program execution • Declare either within or outside of a function – If declared outside a function the variable is global in scope i e known to all functions of the program • Use “normal” declarations Example: int count; |

8051 Embedded ‘C’ Programming
8051 Embedded ‘C’ Programming Definition: An embedded system is an application that contains at least one programmable computer (typically in the form of a microcontroller a microprocessor or digital signal processor chip) and which is used by individuals who are in the main unaware that the system is computer-based Introduction to Embedded C |
What is a 8051 microcontroller?
The 8051 is an 8-bit microcontroller with 8 bit data bus and 16-bit address bus. The 16 bit address bus can address a 64K( 216) byte code memory space and a separate 64K byte of data memory space. Besides internal RAM, the 8051 has various Special Function Registers (SFR) such as the Accumulator, the B register, and many other control registers.
Can assembly instructions be embedded into 8051 C programs?
Assembly instructions can be embedded into 8051 C programs if it is necessary. Most microcontrollers have a dedicated C compiler available just like the 8051 C for “8051” family microcontrollers.
Which peripheral functions are supported by 8051?
8051 is supported with on-chip peripheral functions like I/O ports, Timers/ Counters, Serial communication port. Its primary elements are an Accumulator (AC), Stack Pointer (SP) Program Counter (PC), Program Status Word (PSW), Data Pointer (DTPR) and few more 8-bit register.
What is the difference between code and data memory in 8051?
The 8051 has a separate memory space for programs (Code) and data. Program memory stores the programs to be executed, while data memory stores the data like intermediate results, variable and constants required for the execution of the program. The executable program is stored in this code memory.
4.4.1 Interrupt Functions
As we discussed above, an interrupt is a triggered event that temporarily suspends the foreground program and lets another background program called an interrupt service routine (ISR) or interrupt handler to deal with the event. An interrupt driven system can do multiple tasks simultaneously. It allows the system to respond to an event and handle t
x = data[i]; return (x); }
This function may also be interrupted by another ISR which calls this function as well so that this lookup function is declared as a reentrant function. The next example is another simple reentrant function which calls itself within the function. void recursive(unsigned int value) reentrant {if (value>0) recursive(--value); } If a reentrant functio
4.7 Modular Programming in C
It is clear that a single source file or “module” is sufficient to hold the entire C program. Modular programming, however, is a “divide and conquer” software design and programming technique which breaks up a large program into manageable subpro-gram units such as functions and subroutines. Each module represents a separation of concerns which imp
4.7.1 Scope of Functions and Variables
In a multi-module C program, one module may need to call functions defined in other modules. Multiple modules may share some data, and some data may need to be transferred from one module to other modules. The scope of data and functions must be specified properly to avoid data and program corruption. typical 8051 application consists of many modul
MODULE1.c
extern int a; int exfunc(int x) { int d ; static int count ; count++ ; link.springer.com
d = x * a ; return(d) ; }
The module1.c makes an external reference to the global variable a to use it in exfunc(). The local variable count is defined as a static variable so that it will remember its value after the exfunc() function call exits. When the exfunc() function is called again, the count variable will operate on its previous kept value, which is different from
4.7.3 Multi-module C Programming
We know the header file plays a role of interface between the modules with data and function definition and the modules referencing these data and functions. Here is a simple example with two modules connected by a header file. The main program has an infinite loop calling a function f() which is defined in another module named module1. The MyHeade
