极海APM32F411V Tiny开发板评测08 APM32F4xx_DAL_Driver工程模板建立这几天在极海半导体官网逛的时候看到了APM32F4xx_DAL_SDK相关东西比较好奇，所以研究了研究。APM32F4xx_DAL_Driver是APM32F4系列的类似STM32-HAL抽象层的库，国产APM32芯片从标准固件库终于到HAL库了。 1. 准备目标硬件（开发板/芯片/模组）本教程将极海APM32F411 Tiny开发板进行示例移植，其他 ARM Cortex M4系列开发板和芯片移植方法类似。调试ARM Cortex M核还需要仿真器，如果您的开发板或者芯片模组没有板载仿真器，就需要连接外置的仿真器，如J-Link、DAPLink之类的。 2.准备编译器环境本移植指南针对的是Keil编译器，所以我们移植内核前需要先安装Keil编译器，能编译ARM Cortex M核的Keil编译器现在也叫MDK。 下载地址为：https://www.keil.com/demo/eval/arm.htm 3. APM32F4xx_DAL_Driver APM32F4xx_DAL_Driver是极海APM32F4 DAL SDK的一部分，APM32F4xx_DAL_Driver与STM32_HAL_Driver类似,属于抽象层库，同系列的芯片，使用同一套API函数，应用层快速迭代，丰富的组件和驱动抽象层。APM32F4XXDALSDK内容组成： 下载地址APM32F4 DAL SDK https://www.geehy.com/support/online_detail?id=75 APM32F4 DAL SDK组成

4. 工程创建文件结构 工程以GPIO例程作为基础创建。 1.Board
Source/board_apm32f411_tiny.c
Include/board_apm32f411_tiny.h
2.Libraries
Libraries/APM32F4xx_DAL_Driver/Include
Libraries/APM32F4xx_DAL_Driver/Source
Libraries/CMSIS
Libraries/Device
3.Middlewares
FreeRTOS/RT-Thread/LwIP/Fat_Fs等
4.Project
Project/MDK Project/IAR Project/GCC
Source/main.c 等
Include/main.h等
Config/Source/apm32f4xx_device_cfg.c等
Config/Include/apm32f4xx_device_cfg.h等
添加文件 Config配置文件（选择性配置）
上面的配置过程中，由于后面我们要开启log功能，我们需要打开 USE_LOG_COMPONENT 和 DAL_UART_MODULE_ENABLED - /* Configuration settings for log component */
- #define USE_LOG_COMPONENT 1U
- /* Include log header file */
- #include "apm32f4xx_dal_log.h"
添加串口驱动 由于在GPIO端口工程中，没有配置UART，因此需要进行配置 添加apm32f4xx_usart_cfg.c apm32f4xx_usart_cfg.h 对串口进行端口，波特率等配置 - /* Includes ***************************************************************/

成功点亮。
在apm32f4xx_device_cfg.c中开启log打印组件，调试调试
