LPC900 Studio Restrictions

For the LPC900 Development Studio is a restricted version of the Keil C51 tool chain. The following restrictions apply:

• The 8051 compiler, assembler, linker, and debugger are limited to 4 Kbytes of object code but source code can be any size. Programs generating more than 4 Kbytes of object code will not compile, assemble, or link.
• The debugger supports 4 KByte files or smaller.
• No hardware support is available for multiple DPTR registers.
• No support is available for user libraries or floating point arithmetic.
• Libraries created with this tool chain cannot be used since they have a restricted format.

The following components, which are present in the PK51 Full Version, are not included in the LPC900 Version:

• Linker for Code Banking
• Library Manager
• RTX-51 Tiny Real-Time Operating System

  Details may be found in the \KEIL\C51\HLP\ISD51.CHM help file.

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 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 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.
