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
    • I2C_SPEED define moved to stm32f429i_discovery.h file
  • stm32f429i_discovery_sdram.c
    • Update device refresh counter value to fit with SDRAM timing characteristics
  • Miscellaneous robustness improvement
  • Miscellaneous comments update
