VMLAB Tutorial for Beginners

For software writing and mild simulation, the tool used is Visual Micro Lab. Visual Micro Lab, generally referred to as VMLAB, is a virtual prototyping design framework, especially designed for AVR and ST6 controllers. VMLAB compiler is used to write code for AVR microcontrollers, for example, ATmega16 microcontroller. In this article, you will learn how to use it for writing your first project for an AVR microcontroller. It is a getting-started guide for AVR microcontroller coding. You can download the VMLAB software from the following link:

It is a combination of:

  • A powerful multi-window multi-file text editor.
  • A microcontroller IDE with integrated tools.
  • A symbolic processor.
  • A mixed-mode analog-digital circuit simulator.
  • A code quality checker.

VMLAB Introduction

VMLAB is a virtual prototyping design framework, specifically created for AVR and ST6 controllers. It provides a powerful combination of features including a multi-window multi-file text editor, a microcontroller IDE with integrated tools, a symbolic processor, a mixed-mode analog-digital circuit simulator, and a code quality checker. With VMLAB, hardware and software are co-simulated, offering a true virtual microcontroller design lab experience.

  • Start the VMLAB program by clicking on: Start >> Programs >> VMLAB
  • Create a Project File, selecting the microcontroller and software modules. Use the command New Project, Open Project or Open Last Project to work in a project created
create project in VMLAB
create project in VMLAB

After that select a microcontroller you are using in your project. Check the following figure:

Build the hardware/software database using the command “build”. Any errors or warnings will be shown in the messages. The automatic in-line error reporting feature of VMLAB allows for fast error location, as it takes you directly to the source line responsible for the error. Simply double-click on the reported error.

When all errors are removed, VMLAB enables the green light button. Click on it to run the application. At this step, variables, hardware signals, the microcontroller’s registers, memory, and peripherals can be controlled.

When the application behavior is okay, you can obtain the target .HEX file, which is ready to be burned onto the micro EPROM or OTP, and so on.
