* @brief This file provides the software which contains the main menu routine.
|
|
* The main menu gives the options of:
|
|
* - downloading a new binary file,
|
|
* - uploading internal flash memory,
|
|
* - executing the binary file already loaded
|
|
* - configuring the write protection of the Flash sectors where the
|
|
* user loads his binary file.
