Creating First Project inmikroBasic for dsPIC

In this simple tutorial, we will create a new project, write some code and compile itin mikroBasic for dsPIC and test the results. Our project will make LED diodesblink, so it can be easily tested on dsPIC microcontrollers.

Here is the connection scheme you’ll need to test the code for microcontroller. We have used commonchip in our examples, but you may use any other microcontroller. LED diodes are connected toPORTB, but you can use any other available port – you would need to replace few lines in the code,as explained in the following pages.

Install the mikroBasic for dsPIC compiler. Desktop shortcut and start menu shortcuts will be created.

Run the mikroBasic for dsPIC compiler. mikroBasic IDE (Integrated Development Environment) willappear.

Project Wizard dialog will appear - fill the dialog with appropriate settings for your project:

- Enter a name for your new project,- Choose project path,- Enter short text which describes your project (this is optional),- Choose the microcontroller from drop-down menu (we have chosen

the one that is used in schematic for selected microcontroller, you may selectany other),

- Set the device clock by entering the value in edit box (we have set the same valueas drawn in schematic),

- Set configuration bits (Device Flags) by clicking Default,- After you have set up your project, click OK to continue.

Step 4: Set up your project

Step 5: Write the codeCompiler will create the project file andan accompanying source file, namedsame as your project. This source filewill be automaticaly opened in theCode Editor, so we can write the sourcecode. This is the Code Editor: (

Here is the code that will make LED’s on PORTB blink every second. Type it in the Code Editor (ifthere is any default code you can over write it):

Note: If you want to try another port, just replace each instance of LATB and TRISB in code withyour port, e.g. LATC/TRISC.

Now it’s time to build our project. First, save your file by clicking on the Save Icon, or click Ctrl+S.Select Project > Build from the drop-down menu, or click the Build Icon. You can also use the short-cut Ctrl+F9.

Build.

end.

Step 6: Build!

Compiler will generate output files in the project fold-er. There should be 4 new files: ProjectName.asm,ProjectName.lst, ProjectName.mcl, andProjectName.hex. The last one will be used toprogram the microcontroller directly.

Step 7: Real World testTo “burn” the dsPIC you can use the compiler’s integrated (dsPICprog) programmer (default shortcutis F11) or any other programmer for selected microcontroller. As a result, LED’s connected to PORTBof programmed microcontroller should blink indefinitely.
