然后是配置两个参数,一个在board.h里,定义BSP_USING_ON_CHIP_FLASH,一个是在stm32xxxx_hal_config.h里定义HAL_FLASH_MODULE_ENABLED,这个步骤在board.h里面可以看到: /** if you want to use on chip flash you can use the following instructions. * * STEP 1 define macro related to the on chip f...

而设备驱动框架层,提供了ops操作接口,分别以下的接口需要驱动开发者实现注册。 (二)创建hwtimer设备 对hwtimer设备来说,在驱动开发时,需要先从rt_hwtimer_t结构中派生出新的hwtimer设备模型,然后根据自己的设备类型定义私有数据域。 同样先楫的hwtimer drivers也定义了自己的由rt_hwtimer_t派生出来的hwtimer设备。
从RT-Thread v3.0.4版本到v3.1.0版本，总计有约470个提交，新增约8.5万行代码，移除了19万行代码。主要有以下调整：内核：增加内核对象类型检查，增加device_ops接口，从内核中移除应用模块（到组件中，并重写管理部分代码）；组件：增加SAL、AT组件；BSP：增加对realtek rtl8710bn wifi soc，树莓派2B ...
