## STM32 Standard Peripherals Library Utilities update History

### 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.
- Add new functions to check the SDIO peripheral and SD Card status at any time: SD_WaitReadOperation(), SD_WaitWriteOperation(). The software sequence is little bit changed but without any impact on driver API. For more details, refer to the stm32_eval_sdio_sd.c driver description.
- Add new structure containing the SD Status register parameters. This structure is called by the SD_SendSDStatus() function.
- Transfers mode updated

- Read/Write Block using Polling and DMA modes
- Read/Write Multi Blocks using DMA mode only
- Interrupt mode removed

- Data transfer functions are managing only fixed Block size (512-byte)

- STM32100B-EVAL

- stm32100b_eval_cec.c: fix some strict ANSI-C errors

- STM32100E-EVAL

- stm32100e_eval_cec.c: fix some strict ANSI-C errors

### V4.4.0 / 31-December-2010

Main Changes
