## Contents STM32 Evaluation Board Common Drivers update History License ## STM32 Evaluation Board Common Drivers update History ### V5.0.2 / 05-March-2012 Main Changes All source files: license disclaimer text update and add link to the License file on ST Internet. ### V5.0.1 / 28-December-2011 Main Changes All source files: update disclaimer to add reference to the new license agreement ### V5.0.0 / 30-September-2011 Main Changes Update STM32 Evaluation Board Drivers architecture and folder organization, full API compatibility maintained vs. V4.6.2 All the HW drivers required for each board are provided within this board folder. The concerned drivers are: stm32_eval_i2c_ee.c\.h: I2C M24CXX EEPROM memory driver stm32_eval_i2c_tsensor.c\.h: I2C LM75 temperature sensor driver stm32_eval_spi_flash.c\.h: SPI M25Pxxx FLASH memory driver stm32_eval_sdio_sd.c\.h: SDIO SD Card memory driver stm32_eval_spi_sd.c\.h: SPI SD Card memory driver These drivers were moved from \Common to \STM32XXX_EVAL folder(s) \Common folder contains only drivers for the fonts and log module used by the LCD driver stm32_eval.c\.h files removed, as consequence you need to perform the following update on your project configuration (based on EVAL drivers V4.6.2): In the project files, add your EVAL board driver source file (ex. "stm3210c_eval.c") instead of "stm32_eval.c" Include your EVAL board driver header file (ex. #include "stm3210c_eval.h") instead of #include "stm32_eval.h" If you are using the EVAL board's LCD, you need to add the include of the LCD header file (ex: #include "stm3210c_eval_lcd.h") If you are using the LCD log module, after copying it to the application folder you have to edit it and update the name of the LCD header file. For more details, refer to the lcd_log_conf_template.h driver description. ### V4.6.2 / 22-July-2011 Main Changes STM3210C_EVAL stm3210c_eval_lcd.c: update to support new LCD AM240320D5TOQW01H (controller ILI9325) STM322xG-EVAL stm322xg_eval.h: fix value of the SDIO clock divider (SDIO_TRANSFER_CLK_DIV constant) to 2 instead of 0 stm322xg_eval_lcd.c: increase FSMC AddressSetupTime value from 1 to 3 to be compliant with some LCD access timing stm322xg_eval_audio_codec.c: update Codec_CtrlInterface_Init() and Codec_GPIO_Init() functions to not reconfigure the I2C peripheral if it's already enabled and configured (to avoid configuring the I2C twice when using both Audio codec and IO Expander drivers in the same application). ### V4.6.1 / 18-April-2011 Main Changes Update some STM322xG_EVAL drivers (no change on the API) to fix warnings with TASKING C compiler. Change the Release Notes name to STM32 Evaluation Board Drivers stm322xg_eval.c SD_LowLevel_Init(): change SDIO pins speed configuration to "GPIO_Speed_25MHz" ### V4.6.0 / 11-March-2011 Main Changes Official version supporting STM322xG_EVAL evaluation board RevB (for STM32F2xx devices). Common Add new LCD log utility drivers: The LCD Log module allows to automatically set a header and footer on any application using the LCD display and allows to dump user, debug and error messages by using the following macros: LCD_ErrLog(), LCD_UsrLog() and LCD_DbgLog(). Note: the STM322xG_EVAL board RevA was wrongly named STM3220F_EVAL ### V4.5.0 / 07-March-2011 Main Changes stm32_eval_sdio_sd.c\.h: driver improvement SD Clock increased to 24MHz to improve the data transfer performance.
