### V1.0.1 / 28-October-2013

Main Changes

- stm32f429i_discovery_l3gd20.c, stm32f429i_discovery_lcd.c

- Set SPI baudrate to 5.625 MHz to fit LCD and Gyroscope timing characteristics

- ILI9341 LCD SPI interface max baud rate is 10MHz for write and 6.66MHz for read
- Gyroscope l3gd20 SPI interface max baud rate is 10MHz for write/read

- stm32f429i_discovery_lcd.c

- Improve SPI low level write routines (add check on BSY flag before to deselect the LCD)
- Remove the __IO attribute from these function’s parameters: LCD_SetLayer(), LCD_SetColors(), LCD_GetColors(), LCD_SetTextColor() and LCD_SetBackColor()

- stm32f429i_discovery_i2c_ee.c, stm32f429i_discovery_i2c_ ioe.c

- Add a test in Init() function; if the I2C is already configured, then there is no need to reconfigure it again
