STM32CubeMX移植机智云自动生成代码STM32CubeMX配置GPIO口

STM32CubeMX配置USART外设

STM32CubeMX配置1ms定时器

STM32CubeMX配置外部按键

生成代码

移植代码

从机智云“stm32f103c8x”平台生成的代码中复制Gizwits、Hal、Utils文件夹到当前目录：

在工程中添加如下的目录结构：

修改代码

首先在gizwits_product.h / hal_key.h 中将原来F103C8平台的头文件 #include <stm32f1xx.h>替换为G071RB平台的 #include <stm32g0xx.h>

然后修改如下代码：

修改gizwits_product.c代码：

添加app.c代码：
