设置工程
点击生成代码,并在Keil中打开该工程。
在main函数中的while循环里添加语句
while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, GPIO_PIN_SET); HAL_Delay(500); HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, GPIO_PIN_RESET); HAL_Delay(500); } /* USER CODE END 3 */

将uCOS相关文件复制到HAL工程的MDK-ARM文件夹下
点击 ,然后添加
添加以下文件,在MDK-ARM\uC-CPU和\MDK-ARM\uC-CPU\ARM-Cortex-M3\RealView
然后添加,在\MDK-ARM\uC-LIB和\MDK-ARM\uC-LIB\Ports\ARM-Cortex-M3\RealView
添加,在MDK-ARM\uCOS-III\Ports\ARM-Cortex-M3\Generic\RealView
添加,在\MDK-ARM\uCOS-III\Source
添加,在文件\MDK-ARM\uC-CONFIG

继续修改
找到文件startup_…
在以下位置处将PendSV_Handler和SysTick_Handler改为OS_CPU_PendSVHandler和OS_CPU_SysTickHandler
找到文件app_cfg.h
找到文件includes.h
找到lib_cfg.h
此处修改为5(该处宏定义设置堆空间的大小,STM32F103C8T6的RAM只有20K,所以要改小一点)
gpio.c中修改代码
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); }
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 */
可以看到PA3的波形周期是接近6s的,所以红灯差不多3s转换是否亮
这是PC13的波形,它的周期是在2s,LED灯亮和灭间隔1s
这个是串口的波形
可以看到两次=种方式得到的答案都是一样的
