Keil.stm32L4XX系列的最新DFP。是在keil MDK中开发F0系列的开发包。最新必备。

Keil.STM32L4xx_DFP.2.2.0,keil STM32L4xx版本芯片支持包

STM32L4xx_DFP.2.2.0 提供下，STM32L4xx_DFP.2.2.0 keil的开发库

随着st系列芯片的升级，之前的工程基本使用标准库开发，但是之后的芯片只支持HAL库和LL库，就涉及到项目的迁移，虽然官方资料都提供了，但是很难针对性的找到需要的文档。想从标准库移植到LL库需要以上文档就够了（我的项目是从stm32f103将代码移植到stm32L476时用的）

Version: 2.6.0 (2021-07-30) Keil.STM32L4xx_DFP.2.6.0.pack Updated Pack to STM32Cube_FW_L4 Firmware Package version V1.17.0 Package Description: Added global define USE_FULL_LL_DRIVER to component ::Device:STM32Cube LL:Common. Added debugProbe board description. Device Support: Updated SVD files and documentation. Reworked device RAM size. Added missing devices: STM32L451CETx, STM32L452CETx, STM32L462CETx, STM32L4Q5CGTxP, STM32L4Q5CGUxP, STM32L4Q5VGTxP, STM32L4Q5QGIxP, STM32L4Q5ZGTxP, STM32L4Q5AGIxP, STM32L4Q5RGTxP. Removed devices: STM32L451RCYx, STM32L452RCYx, STM32L485xx. Updated dbgconf files - Add missing variable DoOptionByteLoading. CMSIS Flash Algorithm: Added algorithm for STM32L4RxxG devices. Updated flash algorithms: STM32L4Rx_2048_Dual, STM32L4P5xx_1M, STM32L4P5xx_512: Added empty check, disable interrupts while programming, fix programming while IWDG in HW mode. Fixed last word programming. CMSIS-Driver: USBH: Fixed port resume occasionally getting stuck in resume signaling. Added compile time configuration for reducing Bulk IN NAK rate. SPI: Updated Control function to: Set SPI bus speed only for master mode and disable DMA before reconfigure DMA Updated SPI_GetStatus function with correct error code Updated SPI_GetDataCount function when SPI is not initialized Board Examples: Updated Assembler option to armclang(Auto Select). Updated config files to CMSIS 5.8.0 and MDK-Middleware 7.13.0.

该资源需要配合Keil开发软件方可使用，它包含了stm32l4系列的所有芯片。资源源于官网，在这里分享给大家。

STM32L4xx读写内部FLASH，本人使用STM32L452RET6芯片，使用LL库已调通，由于都是寄存器配置，使用HAL库时修改定义后也是可用； 2019/11/20 后期调了STM32L471VETx芯片，发现擦页不能用，最终找到问题是FLASH页码不连号，只用修改擦页函数的页码号就可以成功擦页，就不再上传了（不适用STM32L4x1系列，需要修改擦页函数）；

主要针对keil编译器开发STM32FL4系列芯片的DFP包，2.2.0版本。

Version: 2.5.0 (2020-10-21) Keil.STM32L4xx_DFP.2.5.0.pack Download Updated Pack to STM32Cube_FW_L4 Firmware Package version V1.16.0 using HAL Drivers V1.12.0 Package Description (pdsc): Added global define USE_HAL_DRIVER to the component ::Device:STM32Cube HAL:Common. Device support: Aligned devices with CubeMX DB. CMSIS Flash Algorithm: Removed targets (STM32L4xx_512, STM32L4xx_256) from STM32L4Rx Flash Algorithm project. Added source code for: STM32L476G-Disco QSPI, STM32L4P5G-DK OSPI, STM32L4P5G-DK PSRAM STM32L4R9I-DK PSRAM, STM32L4R9I-DK OSPI1 and STM32L4R9I-EVAL OSPI. Added PSRAM external Loader support for STM32L4R9I-Disco. Fixed STM32L4P5 1M internal flash Loader sector erase with DBANK mode. Fixed STM32L4xx 512K and 128K internal flash Loader sector erase. CMSIS-Driver: MCI: Replaced empty delay loops with _NOP(). Added handling for separate SD and MMC HAL layers. Added busy signal handling after CMDREND interrupt. SPI: Corrected PowerControl function (to return error if Initialize was not called, to abort active transfer if power off was requested). Updated GetDataCount function to give accurate count. Corrected Uninitialize function (to power off the peripheral if it is powered). USART: Added Driver_USART6 (uses LPUART1). Corrected GetTxCount/GetRxCount implementation. USBD: Removed include of stm32l4xx_hal_pcd.h header. Corrected documentation of STM32CubeMx configuration. Updated Boards Examples: Migrated CubeMX projects to V6.0.1. Changed variant selection to "MDK-Plus" where possible. Updated all USB Host/Device examples with user templates from MDK-Middleware v7.11.1.
