The µVision Debugger offers high-speed Instruction Set and Peripheral Simulation for many ARM devices (Atmel and Philips). Via the ULINK USB-JTAG adapter you can directly connect the µVision Debugger to Embedded ICE of the ARM device.

Product Evaluation

When you install the DK-ARM the first time, the product is installed as an Evaluation Version. To install a full version, you must obtain a License ID Code in the µVision dialog File - License Manager. You may send your Computer ID along with the Product Serial Number via email to support.intl@keil.com.

During Product Evaluation, the following restrictions apply:

  1. The µVision Debugger is limited to 16KBytes program size.
  2. You may not use the Evaluation Version of the µVision Debugger to create commercial products.
  3. We provide the GNU ARM tools (compiler, assembler, and so on). These are not limited or restricted in any way.

Example Programs

Example programs included in the \C51\EXAMPLES folder demonstrate how to use the µVision Project Manager and Debugger (see the µVision 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 µVision IDE is the Device Database which contains information about more than 700 supported microcontrollers. When you create a new µVision project and select the target chip from the database, µVision 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.

Peripheral Simulation

The µVision 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 µVision 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 the Device Database often.
