## What is uVision2?

uVision2 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 \KEIL\C51\EXAMPLES, \KEIL\C251\EXAMPLES, and \KEIL\C166\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 uVision2

To build (compile, assemble, and link) an application in uVision2, you must:

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

uVision2 compiles, assembles, and links the files in your project.

### Creating Your Own Application in uVision2

To create a new project in uVision2, 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 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 uVision2

To debug an application created using uVision2, 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.

## Limitations of Evaluation Software

The following limitations apply to the evaluation versions of the C51, C251, or C166 tool chains.

### C51 Evaluation Software Limitations

- The compiler, assembler, linker, and debugger are limited to 2 Kbytes of object code but source code may be any size. Programs that generate more than 2 Kbytes of object code will not compile, assemble, or link.
- The startup code generated includes LJMP's and cannot be used in single-chip devices supporting less than 2 Kbytes of program space like the Philips 750/751/752.
- The debugger supports files that are 2 Kbytes and smaller.
- Programs begin at offset 0x0800 and cannot be programmed into single-chip devices.
- No hardware support is available for multiple DPTR registers.
- No support is available for user libraries or floating-point arithmetic.

The following components, which are present in the PK51 Full Version, are not included in the C51 Evaluation Software:

- Code-Banking Linker/Locator.
- Library Manager.
- RTX-51 Tiny Real-Time Operating System.

### C251 Evaluation Software Limitations

- The compiler, assembler, linker, and debugger are limited to 4 Kbytes of object code but source code may be any size. Programs that generate more than 4 Kbytes of object code will not compile, assemble, or link.
- The debugger supports files that are 4 Kbytes and smaller.

### C166 Evaluation Software Limitations

- The compiler, assembler, linker, and debugger are limited to 4 Kbytes of object code but source code may be any size. Programs that generate more than 4 Kbytes of object code will not compile, assemble, or link.
- The debugger supports files that are 4 Kbytes and smaller.

## Example Programs

Example programs included in the \KEIL\C51\EXAMPLES directory demonstrate how to use the uVision2 Project Manager and Debugger (see the uVision2 Quick Start Guide for details). Please refer to these if you are new to the tools and want to get started quickly.

## Device Database™

A unique feature of the Keil uVision2 IDE is the Device Database™ which contains information about more than 400 supported microcontrollers. When you create a new uVision2 project and select the target chip from the database, uVision2 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 uVision2 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 uVision2 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.
