From the above statement, it is clear that the Software part of an Embedded System is equally important as the Hardware part. There is no point in having advanced Hardware Components with poorly written programs Software. In the process of making a better embedded system, the programming of the system plays a vital role and hence, the selection of the Programming Language is very important.
The following are few factors that are to be considered while selecting the Programming Language for the development of Embedded Systems. Earlier Embedded Systems were developed mainly using Assembly Language. Even though Assembly Language is closest to the actual machine code instructions and produces small size hex files, the lack of portability and high amount of resources time and man power spent on developing the code, made the Assembly Language difficult to work with.
There are other high-level programming languages that offered the above mentioned features but none were close to C Programming Language. Some of the benefits of using Embedded C as the main Programming Language:. The C Programming Language provided low level memory access using an uncomplicated compiler a software that converts programs to machine code and achieved efficient mapping to machine instructions. The C Programming Language became so popular that it is used in a wide range of applications ranging from Embedded Systems to Super Computers.
The Embedded C Programming Language uses the same syntax and semantics of the C Programming Language like main function, declaration of datatypes, defining variables, loops, functions, statements, etc.
There is actually not much difference between C and Embedded C apart from few extensions and the operating environment. C Programming Language is generally used for developing desktop applications, whereas Embedded C is used in the development of Microcontroller based applications.
Now that we have seen a little bit about Embedded Systems and Programming Languages, we will dive in to the basics of Embedded C Program. A Keyword is a special word with a special meaning to the compiler a C Compiler for example, is a software that is used to convert program written in C to Machine Code. Data Types in C Programming Language or any programming language for that matter help us declaring variables in the program.
There are many data types in C Programming Language like signed int, unsigned int, signed char, unsigned char, float, double, etc. In addition to these there few more data types in Embedded C.

United Kingdom. First Prev Next. Member Thanks for the original post. Is there a post for the dc motor. Thanks in advance B. Thanks for sharing such a nice information about programing micro controller Need Help If still available gjimmy9 8-Nov I am a student in a group trying to construct a code using the microchip for a mini scrolling led sign and cant figure out how to make the source code can you possibly give us a hand??
Ernesto Lizamatm. Hello, good night everyone know that I am relating to grief with a PIC16F84 on how to program in C and I can do a pulse counter to make an increase and a decrease by if they can help me a little as I can do it thanks. It does have delay. Don't you only include. Is this a mistake in the above code? If not, how are you doing it? Where do you put delay.
If it is a mistake, please detail on what needs to be done to correct. Thanks for your help Bret. Re: delay. I have long stopped using PIC microcontrollers and now use C on. NET Micro Framework supported devices, but in any case, you have to copy the delay. Hey ob leowdeo Mar Wats up maxmus. I must say you are representing back from the days of smack. Re: Hey ob mbyamukama Mar It is in fact no longer supported in recent PIC16 products.
Been quite away from PIC16s for a while. Please go to the "samples" directory and look for the "extended directory". Or just make a search inside the "samples" directory. In the install directory of the PIC C compiler. Hi Ken M. Do you mean the programming or the circuit itself?? I meant the circuit itself. Any help would be wonderful. Where can i find pic. Re: Where can i find pic. Here are the steps to load the code onto the microcontroller.
The simulation is a decision analysis and support tool, which is used to know the performance of the circuit. The hardware is the cost-effective equipment, so the proposed action cannot be directly observed by the hardware.
There are different types of simulating softwares available in the market for checking the circuit performance. Here Proteous software is used to check the circuit performance. These are the necessary steps for PIC microcontroller programming to develop simple project.
Hope that you might have got a basic idea on this topic. Any further assistance to build the PIC based projects or any microcontroller based projects you can contact us by commenting below. I am trying to develop a x-y axis motion system on PIC16fa. I have the hardware and the proteus and Mplab software. But I dont know how to start and how many number of ICs I require for achieving this. Any and every help is appreciated.
Thank you. Hii sir, I am student and I have given project based on pic microcontroller,by using pic we control the speed of DC motor by producing pwm.. Hello, thank you for the article, gets basic understanding on pic microcontroller. Am working on one project which requires the functionality as when we give one pulse analog then counter should increase on display and timer enables for certain amount of time ms.
Please suggest what steps need to take. The project is to control the speed of v dc motor using pic microcontroller with help of pwm. And future we have to contol the duty cycle of pwm with the help of android phone via wii or bluetooth module. Sir please help me sir. The program does not work on for me. Can some help and correct?
