低功耗STM32L476RG的 驱动，很好用，特地来分享一下

STM32L4_USRCLOUD_V1.0.0

该文件是使用stm32完成远程升级功能,是我在项目中正常使用的,已经删除库文件,该工程不能直接编译,需要复制函数出来,放在自己的代码中使用.

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.

完整的MDK5工程，主要测试STM32L4几种低功耗模式，亲测电流在0.4ua左右，模式可选，且周期性唤醒 并且包含多种函数接口 可直接调用，FLASH读写结构体 FLASH读写ADC采集电压值 ADC采集电压 RTC实时时钟 RTC实时时钟串口显示 RTC闹钟配置 代码书写规范 注释清楚

STM32L476官方NUCLEO开发板，通过串口实现和匿名上位机/山外上位机(自己DIY四轴或者参加过飞思卡尔智能车的都知道)数据双向通信
