SRAM_Init() function: add FSMC_AsynchronousWait field to FSMC_NORSRAMInitStructure stm3210e_eval_lcd.c LCD_FSMCConfig() function: add FSMC_AsynchronousWait field to FSMC_NORSRAMInitStructure ### 4.2.0 - 04/16/2010 General I2C EEPROM driver update to use the DMA to perform data transfer to/from EEPROM memory. Utilities STM32_EVAL stm32_eval_i2c_ee.c: updated to use the DMA to perform data transfer to/from EEPROM memory. For more details, refer to the description provided within this file. stm3210c_eval.c: add low level functions to configure the DMA (needed for I2C EEPROM driver) stm3210c_eval_ioe.c: add a delay in IOE_TS_GetState() function to wait till the end of ADC conversion stm3210e_eval_fsmc_nor.c: add PD6 pin configuration in NOR_Init() function stm3210b_eval_lcd.c: remove the second ";" from "static void PutPixel(int16_t x, int16_t y);;" ### 4.1.0 - 03/01/2010 General Add support for STM32 Low-density Value line (STM32F100x4/6) and Medium-density Value line (STM32F100x8/B) devices. Add support for the STMicroelectronics STM32100B-EVAL evaluation board. Utilities STM32_EVAL Add new directory "Common" containing a common drivers for all STM32 evaluation boards: fonts.h/.c, stm32_eval_i2c_ee.h/.c, stm32_eval_spi_flash.h/.c, stm32_eval_i2c_tsensor.h/.c, stm32_eval_spi_sd.h/.c and stm32_eval_sdio_sd.h/.c Add new driver for the STM32100B-EVAL managing Leds, push button and COM ports.
