Example description
===================

This directory contains a set of sources files that build the application to be
loaded into into Flash memory using Device Firmware Upgrade demo.

This example provides a description of how to configure an external interrupt 
line. In this example, the EXTIT line 7 is configured to generate an interrupt 
on each falling edge. In the interrupt routine a led connected to P1.01 will be
toggled.
This led will be toggled due to the softawre interrupt generated on EXTIT Line7 
then at each falling edge.

Directory contents
==================
75x_conf.h  Library Configuration file
75x_it.c    Interrupt handlers
main.c      Main program

Hardware environment
====================
Connect a push-button to P1.05 pin with a resistor and a capacity to generate
edges on EXTIT line 7 (Key push-button in STR75x-EVAL board).
Connect a LED to P1.01 pin (LD2 in STR75x-EVAL board)

How to use it
=============
In order to load the project example with the DFU, you must do the following:
 + EWARMv5:
   - Open the project.eww workspace
   - Rebuild all files: Project->Rebuild all
   - A binary file project.bin" will be generated under "user application\Exe" 
     folder 
   - Finaly load this image with DFU application

 + RIDE
    - Open the project.rprj project
    - Rebuild all files: Project->build project
    - Run "hextobin.bat"
    - A binary file "project.bin" will be generated under "\obj" folder
    - Finaly load this image with DFU application

 + RVMDK (Full version is required)
    - Open the project.Uv2 project
    - Rebuild all files: Project->Rebuild all target files
    - Run "axftobin.bat"
    - A binary file "project.bin" will be generated under "\Output" folder
    - Finaly load this image with DFU application
  
  + HiTOP     
    - Open the HiTOP toolchain, a "using projects in HiTOP" window appears.
    - Select open an existing project.
    - Browse to open the project.htp.
    - Rebuild all files: Project->Rebuild all.
    - Load the project: Click on ok in the "download project" window.
    - Run "hextobin.bat"
    - A binary file "Project.bin" will be generated under "Objects" folder.
    
       
 + The generated .bin file should be converted to the DFU format using the DFU File
   Manager Tool included in the DfuSe PC software install. For more details on
   how to convert a .bin file to DFU format please refer to the UM0412 user manual
   Getting started with DfuSe USB device firmware upgrade STMicroelectronics extension
   available from the STMicroelectronics microcontroller website www.st.com.
