1：环境
WIN11
STM32CubeMX 6.15.0
keil5.38
STM32F103C8T6
STLINKV2
USB转TTL(CH340)
rt-thread 3.13(在 STM32CubeMX 下载就可以了)

2: 创建工程

download:https://www.rt-thread.org/download/cube/RealThread.RT-Thread.pdsc

设置自带的LED PC13 为推免输出

配置USART

配时钟


配工程


去掉重复的 可以手动去stm32f1xx_it.c 文件去注释掉 函数
相当于注释掉 【stm32f1xx_it.c】中【HardFault_Handler】、【SysTick_Handler】

右上角【GENERATE CODE】

如果刚创建的新项目，可以点 openproject，或打开目录 双击 用STM32CubeMX 打开
如果已经用 keil5 打开的，用STM32CubeMX 重新配置选项，直接点close，keil5里面会提示是否重新加载呢
这里直接点 openproject 打开如下

右键项目 或 点击魔法棒 打开 目标配置选项，一般默认就好

这增加创建一个HEX 文件

为了串口输出用 不勾选 WIN11下，没输出

有什么调试器就选择什么调试，这里用stlinkv2

3:代码

修改 kservice.c
修改前

修改后

#include "usart.h"
RT_WEAK void rt_hw_console_output(const char *str)
{
    /* empty console output */
	rt_enter_critical();
	/* 直到字符串结束 */
	while (*str!='\0') {
	/* 换行 */
		if (*str=='\n') {
			HAL_UART_Transmit(&huart1,(uint8_t *)'\r',1,0xFFFF);
		}
		HAL_UART_Transmit(&huart1,(uint8_t *)(str++),1,0xFFFF);
	}
	/* 退出临界段 */
	rt_exit_critical();
}

4：编译
报错

要么增加宏定义，（这里才用增加宏定义 省事）

或到 STM32CubeMX 中 RT-Thread 去修改下
