# Release Notes for STM32F4xx-Nucleo Board Drivers Copyright 2015 STMicroelectronics
## Update History ### V1.2.3 / 13-November-2015 Main Changes stm32f4xx_nucleo.c Add SD_IO_CSSState(), SD_IO_WriteReadData() and SD_IO_WriteReadData() APIs for proper support of the Adafruit shield V2.0.1 Add new API for Button, LED and Joystick deinitialization: BSP_PB_DeInit(), BSP_LED_DeInit(), BSP_JOY_DeInit() Replace static APIs SPIx_Read(), SD_IO_ReadByte(), SD_IO_WriteCmd(), SD_IO_WaitResponse() and SD_IO_WriteDummy() by SD_IO_WriteReadData() API. stm32f4xx_nucleo.h Add new define "ADAFRUIT_TFT_JOY_SD_ID802" for the Adafruit TFT shield support. ### V1.2.2 / 14-August-2015 Main Changes stm32f4xx_nucleo.h Add alias to BUTTON_USER for backward compatibility. ### V1.2.1 / 02-March-2015 Main Changes stm32f4xx_nucleo.c/.h Align to STM32F4xx HAL Driver V1.3.0 for __HAL_RCC_PPP_CLK_ENABLE() . ### V1.2.0 / 26-December-2014 Main Changes stm32f4xx_nucleo.c Add LCD_IO_WriteMultipleData() LCD IO function, needed for ST7735 BSP component driver. Note: This driver version V1.2.0 needs ST7735 BSP component driver V1.1.0 and later. ### V1.1.1 / 10-December-2014 Main Changes stm32f4xx_nucleo.c BSP_BP_Init(): Fix limitation on button pin configuration (change EXTI polarity from rising to falling) ### V1.1.0 / 19-June-2014 Main Changes stm32f4xx_nucleo.c/.h Update driver to support LCD, joystick and microSD available on Adafruit 1.8" shield (reference ID 802) by adding the SPI and ADC IO link operations Enhance BSP_PB_Init() function by removing the call of __SYSCFG_CLK_ENABLE() already enabled in the HAL_GPIO_Init() Correct BSP_LED_Off() and BSP_LED_On() by inverting GPIO_PIN_RESET/ GPIO_PIN_SET values written on GPIO pins Comments clean up and typo corrections ### V1.0.0 / 18-February-2014 Main Changes First official release ## 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.
