#Pic Controller Code More Readable#

The point is that you need more than theory to make the microcontroller do something useful.DC motor control with PIC16F877A and L293D circuit: In the circuit there are 3 push buttons, 2 for selecting the direction and the other one for stopping the motor. You will experience many problems with accurate names of registers, their addresses, names of particular control bits and many others when you start writing your first program in Basic. It is useful to know, of course, but donвЂ™t forget that this programming language is not much in connection with something concrete and tangible. Download Real Pic Simulator - PIC Microcontroller Simulator - Xtronic.Everything you have read so far about programming in Basic is just a theory. Successful docking is achieved when all green numbers in the center of the interface are below 0.2.Movement in space is slow and requires patience & precision.Download Gpsim Software Simulator For Microchip PIC Microcontrollers - Xtronic. This simulator will familiarize you with the controls of the actual interface used by NASA Astronauts to manually pilot the SpaceX Dragon 2 vehicle to the International Space Station.

Now, when you know enough about it, itвЂ™s time to present the software you are going to use for developing and editing your projects. We have previously introduced mikroBasic language which has been especially designed for programming PIC microcontrollers. ItвЂ™s about software used for programming similar microcontrollers of one manufacturer. There is no such a compiler sutable for only one type of microcontrollers nor for all microcontrollers. First of all, you need a program installed on your PC which understands the programming language you are going to use and which provides appropriate working environment for it.

You can get it for free (no ads etc) on Android, or so-cheap-it's-nearly-free on the Apple app store, or free-but-donate-if-you-like-it on Windows.As its name implies, the mikroBasic PRO for PIC compiler is intended for writing programs for PIC microcontrollers in the Basic language. At the moment it concentrates mainly on gliders, but it has a few other aircraft too and I expect the stable will expand in the near future. Programming 8-bit PIC Microcontrollers in C: With Interactive Hardware.PicaSim is a flight simulator for radio controlled aircraft. ItвЂ™s IDE (Integrated Development Environment) includes all the tools you need to develop your projects (editor, compiler debugger etc.)Interfacing PIC Microcontrollers: Embedded Design by Interactive Simulation.

Creation of the project (project name, project settings, file dependancies) Programming and Customizing the PIC MicrocontrollerPIC Basic.The process of creating and executing a project can be divided in several parts: You can finally start writing your program in Basic.Pic Microcontrollers For Everyone Made Easier With Pic Simulator Ide Basic Compiler. So, the first thing you have to do when you start up the compiler is to select the chip and operating frequency from the list. Moreover, it includes specific tools for PIC microcontroller programming.

Hex file genertaed by the compiler into the microcontroller by using the PICflash programmer).The installation of mikroBasic PRO for PIC is similar to the installation of any other Windows program and the whole procedure is carried out through Wizard:Build/Debugger Type: The whole compiling process is called building and includes parsing, compiling, linking and generation of. Microcontroller programming (load the. Debugging (execute your program step by step to make sure that it performs the operations you expect)

When the compiling process is completed and the microcontroller is programmed, the compiler remains connected to the microcontroller and still can affect its operation. Hex file in order to allow you to perform hardware debugging. After completing the compiling process, the compiler has no more influence on the program execution.Build type - ICD debug: Some information is added to the. Depending on your choice of mode, the generated file to be loaded into the microcontroller will be different.Build type - release: The program to be loaded into the microcontroller will not contain any complementary information to be debugged later.

When you write a program, donвЂ™t forget comments. A large number of options used for setting its functions and layout can be found in the Tools/Options menu. DonвЂ™t forget to re-build and re-program your device after modifying any of those settings.EDITING AND COMPILING PROGRAMS CODE EDITORCode Editor is a central part of the compiler window used for writing and editing programs. However, it is faster to debug a program by using simulator and it doesnвЂ™t require any taget device.Note that any of these settings can be modified at any time while editing the program. The simulator doesnвЂ™t use real devices for its operation, so that some operations cannot be reproduced (interrupt, for example). It enables you to simulate your program by reproducing the microcontroller behaviour.

In this way, it is much easier to fix compilation errors. You can also compile your program every time the redaction of a new function is completed and test its behaviour by using debug mode. As there is no line length limitation, donвЂ™t hesitate to use blank spaces in order to make your code more readable.When you write a program, compile it regularly in order to correct syntax errors as you come along. Moreover, even if the compiler doesnвЂ™t have formatting restriction, you should always follow the same editing rules (like in the examples provided in this book).

In case you choose ICD debug make sure you load your program into the microcontroller. Whatever mode you choose, the debugging procedure is the same. However, your job is not finished yet because you still donвЂ™t know whether your program behaves as expected or not.As we could see before, there are two debug modes: a software debugger which simulates actions of the microcontroller (default mode) and a hardware debugger (mikroICD) which directly reads the content of the microcontroller memory. When all the errors are fixed, your program is ready to be dumped into the microcontroller. The compilation enables you to correct your program by fixing all mikroBasic errors. In other words, it is advisable to fix errors one by one.In the previous example, the program reports a syntax error in the 80th line.

If the executed program line calls a subroutine, the debugger will not step into it. Step Over: Execute the current program line, then halts. If the executed program line calls a subroutine, the debugger steps into the subroutine and halts after executing the first instruction within it.

Step out: Execute all remaining program lines within the subroutine. Run To Cursor: Execute all the program lines until the cursor position is reached. This command is commonly used when it is necessary to speed up the execution of long program loops. As a result, the state of registers is changed. It seems that one program line is skipped even though the whole subroutine is executed.

Note that the lines marked by breakpoints are highlighted in red. A small window called Breakpoints indicates you where the breakpoints are located. To add or remove a breakpoint you just have to click on the left side of your code editor on the appropriate line or press. This is very useful as you will be able to check only critical parts of the program, not lose your time by testing the whole program line by line.
