&par Example Description

This example shows how to use SPI Peripheral to read and write Flash.
The data will be shown on serial assistant trough usart1.If error, 
LED2 will turn on. if initialize the flash error, LED3 will turn on.

&par Hardware Description

    Connect SPI1 and W25Q16JV pins as follows:
    SPI1 NSS    (PF5)   to  W25Q16JV_CS
    SPI1 SCK    (PB3)   to  W25Q16JV_SCK
    SPI1 MISO   (PB4)   to  W25Q16JV_DO
    SPI1 MOSI   (PB5)   to  W25Q16JV_DI

  - USART1 configured as follow:
  - BaudRate = 115200
  - Word Length = USART_WordLength_8b
  - Stop Bit = USART_StopBits_1
  - Parity = USART_Parity_No
  - Hardware flow control disabled (RTS and CTS signals)
  - Receive and transmit enabled
