1. uVision2 Integrated Development Environment
==============================================
uVision2 is an IDE that encapsulates a project manager, make facility, tool
configuration, editor and a powerful debugger.  You use uVision2 to write
and compile your programs using the Keil tools.  The example programs provided
are designed to work with uVision2.


2. Example Programs and First Steps
===================================
Several sample projects are located in the \C51\EXAMPLES and C166\EXAMPLES
folders.

HELLO    is a simple program which prints the string "Hello World" via the
         Serial I/O Interface.

MEASURE  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.


To build (compile and link) an application:

a)  Select Project - Open Project:  i.e.  C166\examples\hello\hello.uv2
b)  Project - Rebuild all target files or Build target


To create your own applications:

a)  Project - New Project:  select a directory and enter project file
b)  Project - Select Device:  select an 8051, 166, or ST10 device
c)  Project - Targets, Groups, Files:  Add/Files, select Source Group1 and
    add the source files.
d)  Project - Options:  set all the tool options (the defaults are typically
    good settings for first projects, just add the external memory devices
    you are using).
e)  Project - Rebuild all target files or Build target


To debug the application:

a)  Debug - Debugger:  start Debugger
b)  Use Step toolbar buttons or enter in Output Window - Command:  G, main
c)  You can open the Serial Window using the Toolbar "Serial #1" button.
d)  Now you can debug your program with standard options: Step, Go, Break.


3. Restrictions of the C51 or C166 Evaluation Version
=====================================================
If you have installed an evaluation version of the C51 or C166 toolchain 
you have the following restrictions:


PK51/C51 Compiler - Restrictions in the Eval Version
----------------------------------------------------
a) The 8051 compiler, assembler, linker, and debugger are limited to 2 Kbytes 
   of object code.  Source code may be of any size.  Programs that generate more
   than 2 Kbytes of object code will not compile, assemble, or link. 
b) The debugger supports 2 Kbyte files or smaller. 
c) The startup code generated includes LJMPs.  Code generated cannot be used in
   single-chip devices that support less than 2K of program space (like the 
   Philips 750/751/752). 
d) Programs start at offset 0x4000.  Code generated with the evaluation software
   may not be programmed into single-chip devices. 
e) No hardware support for multiple DPTR registers.
f) No support for floating point arithmetic and no support for user libraries.

The following components which are present in the PK51 Full Version are not
included in the PK51/C51 Eval Version:

a) Linker for Code Banking.
b) Library Manager.
c) RTX-51 Tiny Real-time Operating System.


PK166/C166 Compiler - Restrictions in the Eval Version
------------------------------------------------------
a) The 166 compiler, assembler, linker, and debugger are limited to 4 Kbytes 
   of object code.  Source code may be of any size.  Programs that generate more
   than 4 Kbytes of object code will not compile, assemble, or link. 
c) The debugger supports 4 Kbyte files or smaller.
