What's New in µVision3

µVision3 adds many new features to the Editor like Text Templates, Quick Function Navigation, Syntax Coloring with brace highlighting, Configuration Wizard for dialog based startup and debugger setup. µVision3 is fully compatible to µVision2 and can be used in parallel with µVision2.

What is µVision3?

µVision3 is an IDE (Integrated Development Environment) that helps you write, compile, and debug embedded programs. It encapsulates the following components:

• A project manager.
• A make facility.
• Tool configuration.
• Editor.
• A powerful debugger.

To help you get started, several example programs (located in the \C51\Examples, \C251\Examples, \C166\Examples, and \ARM\...\Examples) are provided.

• HELLO is a simple program that prints the string "Hello World" using the Serial Interface.
• MEASURE is a data acquisition system for analog and digital systems.
• TRAFFIC is a traffic light controller with the RTX Tiny operating system.
• SIEVE is the SIEVE Benchmark.
• DHRY is the Dhrystone Benchmark.
• WHETS is the Single-Precision Whetstone Benchmark.

Additional example programs not listed here are provided for each device architecture.

Building an Application in µVision2

To build (compile, assemble, and link) an application in µVision2, you must:

1. Select Project - Open Project (for example, \C166\EXAMPLES\HELLO\HELLO.UV2).
2. Select Project - Rebuild all target files or Build target.

µVision2 compiles, assembles, and links the files in your project.

Creating Your Own Application in µVision2

To create a new project in µVision2, you must:

1. Select Project - New Project.
2. Select a directory and enter the name of the project file.
3. Select Project - Select Device and select an ARM, 8051, 251, or C16x/ST10 device from the Device Database™.
4. Create source files to add to the project.
5. Select Project - Targets, Groups, Files. Add/Files, select Source Group1, and add the source files to the project.
6. Select Project - Options and set the tool options. Note when you select the target device from the Device Database™ all special options are set automatically. You typically only need to configure the memory map of your target hardware. Default memory model settings are optimal for most applications.
7. Select Project - Rebuild all target files or Build target.

Debugging an Application in µVision2

To debug an application created using µVision2, you must:

1. Select Debug - Start/Stop Debug Session.
2. Use the Step toolbar buttons to single-step through your program. You may enter G, main in the Output Window to execute to the main C function.
3. Open the Serial Window using the Serial #1 button on the toolbar.
4. Debug your program using standard options like Step, Go, Break, and so on.

Device Database™

A unique feature of the Keil µVision2 IDE is the Device Database™ which contains information about more than 400 supported microcontrollers. When you create a new µVision2 project and select the target chip from the database, µVision2 sets all assembler, compiler, linker, and debugger options for you. The only option you must configure is the memory map.

As new devices become available, they are added to the database along with data sheets and header files. For information about adding your own chips to the database or about creating your own personal databases refer to the following knowledgebase articles.

• Adding Custom Parts to the Device Database
• Creating Custom Databases

Peripheral Simulation

The µVision2 Debugger provides complete simulation for the CPU and on-chip peripherals of most embedded devices. To discover which peripherals of a device are supported, in µVision2 select the Simulated Peripherals item from the Help menu. You may also use the web-based Device Database™. We are constantly adding new devices and simulation support for on-chip peripherals so be sure to check Device Database™ often.
