This course shows too much detail in how to make firmware API's. I thinks that course content is adequate and good. 有帮助吗? Vikrant 评分:3.0,满分 5 分5 个月前 V Should have spent more time in HAL documentation. Debug
IO操作函数:HAL_PPP_Read(),HAL_PPP_Write(),HAL_PPP_Transmit(),HAL_PPP_Receive()。 控制函数:HAL_PPP_Set(),HAL_PPP_Get()。 状态和错误:HAL_PPP_GetState(),HAL_PPP_GetError()。 在STM32Cube中包含了LL库,目前LL库和HAL库捆绑发布,所以在HAL库源码中,还有一些名为stm32f1xx_ll_ppp的源码文件...
Each package embeds standard drivers, in both optimized (Low-Layer API) and portable (HAL API) versions. Additional middleware suitable for specific MCU or MPU peripherals is available. STM32Cube embedded software can also be found on Github. Explore the list of software components available in...

HAL,英文全称Hardware Abstraction Layer,即硬件抽象层。HAL库是ST公司提供的外设驱动代码的驱动库,用户只需要调用库的API函数,便可间接配置寄存器。我们要写程序控制STM32芯片,其实最终就是控制它的寄存器,HAL库就为了更方便我们去控制寄存器,从而节约开发时间。 本章将分为如下几个小节: 7.1 初识STM32 HAL库 7.2 ...
4.stm32f1xx_hal.c内弱定义了 __weak void HAL_MspInit(void)。 5.stm32f1xx_hal_msp.c中的函数定义相对stn32f1xx_hal.c中的同名函数定义具有优先权,如果在tm32f1xx_hal_msp.c没有定义某外设函数,则使用stn32f1xx_hal.c中的定义的那个函数。

由上图可以看出,中间件或上层应用,通过CMSIS驱动接口,跟底层的硬件进行了隔离。建议组件和应用开发上直接使用CMSIS提供的驱动接口,最好不要直接调用Device(跟特定平台相关的标准库或HAL库)的接口,除非迫不得已。这样可以做到底层硬件的变动而不影响中间件和上层业务。
