# Release Notes for STM32F429 Discovery Board Drivers Copyright © 2015 STMicroelectronics
## Update History ### V2.1.2 / 02-March-2015 Main Changes stm32f429i_discovery.c/.h Align to STM32F4xx HAL Driver V1.3.0 for __HAL_RCC_PPP_CLK_ENABLE() . ### V2.1.1 / 10-December-2014 Main Changes stm32f429i_discovery.c/.h Change I2C_SPEED used define by BSP_I2C_SPEED stm32f429i_discovery_sdram.c BSP_SDRAM_Initialization_sequence(): Fix wrong configuration of the burst length stm32f429i_discovery_gyroscope.h, stm32f429i_discovery_io.h,stm32f429i_discovery_lcd.c/.h and stm32f429i_discovery_ts.h: Change "\" by "/" in the include path to fix compilation issue under Linux Miscellaneous comments update ### V2.1.0 / 19-June-2014 Main Changes stm32f429i_discovery.c/.h Add protection for double initialization of IO_Init within LCD_IO_Init() Enhance BSP_PB_Init() function by removing the call of __SYSCFG_CLK_ENABLE() already enabled in the HAL_GPIO_Init() stm32f429i_discovery_gyroscope.c/.h Update BSP_GYRO_Init() to support new L3GD20 device ID (I_AM_L3GD20_TR) stm32f429i_discovery_ts.c/.h Correct wrong TS configuration BSP_TS_ITConfig() and TS IT implementation, BSP_TS_ITClear() related to the use of IO expander STMPE1600 device not available on stm32f429i discovery board Comments clean up and typo corrections stm32f429i_discovery_eeprom.c/.h Update usage of BSP_EEPROM_TIMEOUT_UserCallback() function ### V2.0.1 / 26-February-2014 Main Changes stm32f429i_discovery_eeprom.c/.h Update usage of BSP_EEPROM_TIMEOUT_UserCallback() function ### V2.0.0 / 18-February-2014 Main Changes Major update based on STM32Cube specification: drivers architecture and APIs modified vs. V1.0.2, and thus the 2 versions are not compatible. This version has to be used only with STM32CubeF4 based development ### V1.0.2 / 06-December-2013 Main Changes Update IO expander interrupt line on stm32f429i_discovery_ioe.h file. ### 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 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 ### V1.0.0 / 20-September-2013 Main Changes First official version of the STM32F429 Discovery Board Drivers ## License Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.
