     This  document  contains  release  notes for V5.0 of the 
     STMICROELECTRONICS ST7 Software Library. This library contains software 
     examples about how to use the ST7 peripherals and development 
     environment in assembly and C languages. 
     The development environment files contain the mapping for the
     dedicated ST7 hardware registers for all the general pupose devices.


==========================< IMPORTANT REQUIREMENT >============================


     ST7 Tools and debugger on PC requires a minimum configuration:
      - PC 386 (387 not required) or higher
      - a minimum of 4 Megabytes of system memory
      - Microsoft Windows 95 operating in enhanced mode or higher.      


     The hardware tools are not required for using the library, you can use
     WGDB7 as a simulator. But for a better development you can use the 
     following Hardware tools:
      - the development Kit (or emu low cost).  
      - the ST7 emulator 
      - the EPROM Programming Board or Gang Programmer.
      
      
     The software tools installation procedure should start with:     
      - the ST7 software tools 
      - the ST7 windows debugger 
      - the ST7 HDS configuration files (configure WGDB7 when it is used 
        with the emulator)
      - the Windows EPROMER .
      These tools are free software and are located on the ST7 CDROM or 
      on ST MCU dedicated web site ( http://mcu.st.com ).
      
     Then, in case of a development in C language you need to use the
     C Tool Chain provided by Hiware (demo version in the STMCU cdrom) or 
     the Hiware web site.
 

================================< CONTENTS >=================================

     This ST7 Software Library can be downloaded from the ST MCU dedicated 
     web site ( http://mcu.st.com ).
     Download the 'zip' file and run the setup.exe files to install the 
     different parts you need.
     
     This library can install the following subdirectories:

WARNING: Only source files and configuration files are located in these 
directories.
If you want to compile, link and format the different examples, you have 
to install the ST7 Hiware C tool chain and check your configuration files 
according to your installation as specified in the C_TIPS.TXT file.
For more details refer to the application note AN989: 'Starting with 
ST7 Hiware C'


DRIVERS Directory:
------------------
               
Section 2.0.01: DOC_C
     Microcontroller: Any (Validated on ST72251)
     Comments: Documentation on the software example (section 2.03).

Section 2.0.02: I2C_POLL
     Microcontroller: Any (Validated on ST72251)
     Comments: Driver for the I2C cell using a polling technique. Validated
               using an external serial EEPROM. This software has been written
               in both C langage and in-line assembler for easier use and can
               be easily adapted to manage the peripheral using interrupts.

Section 2.0.03: PWMB
     Microcontroller: Any with the PWM for DAC cell (Validated on ST7250)
     Comments: Generation of an analog output waveform (50 Hz sinusoid)
               using the PWM/DAC cell.

Section 2.0.04: SCI_311
     Microcontroller: Any with the SCI cell (Validated on ST72311)
     Comments: ST7 SCI peripheral software driver for a RS232 communication
               with a terminal in half-duplex mode.
