mikroLab - essential tools for the efficient developer

Code, compile, program, and debug – all in one environment. Choose the development board, and you’ll soon see that the rest of the tools are perfectly arranged around it.

mikroLab contains everything a developer needs to explore the possibilities of the microcontroller architectures we offer: a development board (with integrated programmer and debugger), the compiler license, an assortment of accessories, and as a bonus, a free license for one of our GUI design tools (either Visual TFT or Visual GLCD).


Manage all your data quickly and easily. Make the workspace comfortable and suited to your need. Use the default layout of the IDE, or arrange the windows manually.

Navigate through all the projects you are working seamlessly and save time with the intuitive IDE of the mikroC compiler.


Advanced Project Management

Edit Project gives you a full overview of the entire set of configuration bits in each chip. Select only among listed options, described in simple terms. Edit project includes predefined schemes of oscillator settings for most widely used microcontrollers. Simply load your desired scheme, and you are ready to go.

Don’t waste your time browsing for examples. Let them come to you. New Project Explorer window leads you to your projects. It displays all of compiler’s many included examples by default. But simply point the path to any other folder and fast recursion-search algorithm will extract all of projects inside and will display a tree view of your project files up to any depth. Double click opens the project and sets it as active. Easily switch between the projects as often as you want, and you will have a stable RAM memory consumption.

Library manager

Only mikroC offers the unique mechanism to easily use any available library in your project. Special OneClick technology allows you to speed up your development. No need for dozens of #include directives.

Just click on the checkboxes of the libraries you need and they will be instantly available in your code. As we always think one step ahead, we programmed Library manager to allow easy usage of third party libraries installed with Package Manager software.

Notice: Visit LibStock and download fully functional and working projects, and install them with a single click.

Library manager
Code Assistant

Code Assistant

Control-space is probably the most widely used shortcut among programmers. Why? Because it initiates Code Assistant - programmer’s first aid kit. No one needs to memorize function names.

Focus on your code, and let the syntax write itself correctly. Write function calls with one click of your keyboard. Code assistant in mikroC PRO for ARM® also suggests correct names of constants, and variables so you have it all covered. You don’t ever have to get another Syntax error message.

Wild Card Code Completion

Use Code Completion for all those times when you need to list identifier names that contain a certain word, or when you only know a part of the identifier name.

Simply type \* in the Code Editor, followed by the phrase, and presses Ctrl+Space - a list of identifiers containing this phrase will be shown.

Interrupt Assistant Window
Active Comment Preview

Active Comments

We have developed Active Comments - a unique feature of mikroC PRO for ARM®. Any comment can become your multimedia event hook.

Add images, files and URLs to any active comment and assign events as you like.

Right Mouse Click can open browser with URL, Mouse Over can display the image, and Double Click can open a specified file.

You can add:

  • Images
  • Files
  • URLs

Add local variable declaration option

Easily declare a local variable.

  • First, enter the desired variable's name in the Code Editor.
  • Then select this option from Edit menu (Shift+Ctrl+V). Here you can the select variable type, dimension, and add a volatile qualifier if needed.
  • After pressing the OK button, a variable declaration will be placed.
Local variable declaration
Interrupt Assistant Window

Interrupt Assistant

The compiler also includes the Interrupt Assistant, that can help you in configuring interrupts.

You can launch it from the drop-down menu Tools › Interrupt Assistant.

Parameter Assistant

Many functions. Even more parameters. Was it word, or byte? You don’t have to scroll through Help file.

Just hit CTRL+SHIFT+SPACE and function parameters will be listed for you.

Parameter Assistant
Code Folding

Code Folding

When your code overgrows the size of your screen, it’s always better to fold those completed blocks, and work in a clearer surrounding.

This way you can always see the big picture.

Built-in tools

What’s the point of a compiler if you have to do all the hard work yourself. mikroC PRO for ARM® offers you several most useful integrated tools that will help you get the job done with minimum effort.

  • Active Comment Editor
  • ASCII chart
  • Export Code To HTML Tool
  • GLCD Bitmap Editor
  • HID Terminal
  • Interrupt Assistant
  • LCD Custom Character
  • Seven Segment Editor
  • UDP Terminal
  • USART Terminal
  • USB HID Bootloader
Built-in tools
Quick Converter

Quick Converter

Your fast pocket converter of binary, float, HEX and Radix 1.15 formats into formats you need in your code.

It even displays ASCII values of your bytes.

In-Circuit Debugging

mikroC PRO for ARM® has native support for hardware step-by-step In-Circuit Debugger when used with fast USB 2.0 mikroProg™ programmer (in both on-board and standalone version), or Stellaris® debuggers. Debugger is a separate DLL module which supports Step-over [F8], Step-into[F7], Step-out[Ctrl+F8], Run[F6], Run To Cursor[F4] debugging operations. Also, debugger supports standard and advanced breakpoints, which enable you to exploit the full potential of fast debugging.

Watch Clock

Software Simulator

If you want to go through your code and monitor the values of your variables searching for bugs and errors, Software Simulator is the best way to do so.

Software simulator supports all debugging modes as hardware debugger, but instead of executing the code on real hardware, it simulates code flow on your PC. Using Watch Clock you can precisely measure the code execution time in microseconds or in clock cycles.

Advanced Statistics

After you build your project, you can always look under the hood with mikroC’s Advanced Statistics. It is a powerful tool that visually describes most important information about your project.

Take a look at your variables, arrays and constants and know how much memory your program consumes. See which function calls which in the functions tree window. See how big are your functions and how are they linked in memory, which is especially important if you want to write your own bootloader applications.

License Code

Choose this licensing option if you want to activate your compiler license in seconds. You can use it on up to two computers. We will send you the Registration code as soon as you purchase the compiler, which you will use to request the Activation code. That is the whole process - your compiler license is activated. It’s the quick and straightforward licensing option for this fast-paced world.

USB Dongle License

Plug the USB Dongle into your computer and activate the license. Use your compiler license anywhere. If you are looking for a portable license that can be used on different computers the USB Dongle license is what you need. The USB Dongle contains a single license, it registers the compiler while it's connected. So, carry it anywhere with you. You will not be tied to one computer or one office.

Site Licenses for MikroElektronika Compilers

The regular licensing model for MikroElektronika software works best for individual users. If you run a two-person team, a whole R&D department, or teach a class, the Site License is a better solution. It allows you to own, manage and deploy multiple single licenses, with some major benefits:

Affordable: Instead of buying multiple licenses at regular price, we will quote a special discounted price. Schools and universities will get the best deals.

Flexible: With the Site license, individual licenses are not tied to individual computers/users. In other words, you don’t have to buy a compiler license for each person who will use it. The number of licenses you own only defines how many compiler copies can be in active use at the same time. You control who has access.

Here's How It Works

  1. Once you purchase a given number of compilers, we will send you the installation for the Site License Manager (available for Windows and Linux). It’s an application that runs a server from your computer.
  2. Enter the Site License activation key in the License Manager application
  3. To give members of your team/class access, simply share IP address and/or PORT number of the Site License server (visible from within the application)
  4. To activate their compiler, members of your class/team connect to the server by entering the IP address and PORT number you gave them.
  5. Once an individual user finishes his work session, the user slot becomes available again
