前言

本文是基于STM32F103C8T6的实验。


一、使用CubeMX建立STM32F103C8T6HAL库

配置RCC

二、准备uCOSIII

准备uCOSIII 密码1234
网盘下载,打开目录如下(文件夹uC-BSP和uC-CONFIG是自己新建的两个文件夹)

三.移植前准备

1.为uC-BSP文件夹新建bsp.c和bsp.h文件

2.给文件夹uC-CONFIG添加以下文件(从以下路径复制过来)

五修改其余文件部分代码

找到文件startup_…

由于我们使用了printf函数,需要在usart.c文件中添加以下代码完成printf重定向

/* USER CODE BEGIN 1 */
int fputc(int ch,FILE *f){
	HAL_UART_Transmit(&huart1,(uint8_t *)&ch,1,0xffff);
	return ch;
}
/* USER CODE END 1 */

gpio.c中修改代码(添加初始化PA3)

void MX_GPIO_Init(void)
{

  GPIO_InitTypeDef GPIO_InitStruct = {0};

  /* GPIO Ports Clock Enable */
  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOD_CLK_ENABLE();
  __HAL_RCC_GPIOA_CLK_ENABLE();

  /*Configure GPIO pin Output Level */
  HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, GPIO_PIN_RESET);
	HAL_GPIO_WritePin(GPIOA, GPIO_PIN_3, GPIO_PIN_RESET);


  /*Configure GPIO pin : PC13|PA3 */
  GPIO_InitStruct.Pin = GPIO_PIN_13|GPIO_PIN_3;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
  HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);
	HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

}
