1, Using STM32CubeMX to build a project

1. Open the software

2. Create project based on chip

3. Select the corresponding chip

• Here I use stm32f429igt6
  

4. Set GPIO

5. Set serial port

6. Set the clock to 180MHz

• Internal clock is selected here. If you need external clock, please customize the configuration
  

7. Project setting

8. Generate project, compile, run and verify

2, TencentOS tiny file migration

1. Get source code

• Official open source address: https://github.com/Tencent/TencentOS-tiny

2. Download it to the local area and extract it as shown in the figure

3. Copy the source file to the mdk project directory

• Open the project directory generated by STM32CubeMX, add the TencentOS tiny folder, and copy the three folders in step 2 to this folder
  
  

4. Add configuration directory and file

• The content of the header file is as follows. Note to modify the name of the imported header file:

#ifndef _TOS_CONFIG_H_
#define  _TOS_CONFIG_H_

#include "stm32f4xx_hal.h"	// Target chip header file, users need to change according to the situation

#define TOS_CFG_TASK_PRIO_MAX           10u 	// Configure the default maximum number of priorities supported by TencentOS tiny

#define TOS_CFG_ROUND_ROBIN_EN          0u		// Configure whether the kernel of TencentOS tiny turns on time slice rotation

#define TOS_CFG_OBJECT_VERIFY_EN        1u	// Configure TencentOS tiny to check whether the pointer is legal

#define TOS_CFG_TASK_DYNAMIC_CREATE_EN  1u		// TencentOS tiny dynamic task creation function macro

#define TOS_CFG_EVENT_EN                1u		// TencentOS tiny event module function macro

#define TOS_CFG_MMBLK_EN                1u		//Configure whether the memory block management module is enabled by TencentOS tiny

#define TOS_CFG_MMHEAP_EN               1u		//Configure whether TencentOS tiny turns on dynamic memory module

#define TOS_CFG_MMHEAP_DEFAULT_POOL_EN  1u		// TencentOS tiny default dynamic memory pool function macro

#define TOS_CFG_MMHEAP_DEFAULT_POOL_SIZE        0x100	// Configure the default dynamic memory pool size of TencentOS tiny

#define TOS_CFG_MUTEX_EN                1u		// Configure whether or not TencentOS tiny turns on the mutex module

#define TOS_CFG_MESSAGE_QUEUE_EN        1u		// Configure whether the message queuing module is enabled by TencentOS tiny

#define TOS_CFG_MAIL_QUEUE_EN           1u		// Configure whether the message mailbox module is enabled by TencentOS tiny

#define TOS_CFG_PRIORITY_MESSAGE_QUEUE_EN	1u	// Configure whether the priority message queuing module is enabled by TencentOS tiny

#define TOS_CFG_PRIORITY_MAIL_QUEUE_EN	1u		// Configure whether the priority message mailbox module is enabled by TencentOS tiny

#define TOS_CFG_TIMER_EN                1u		// Configure whether the software timer module is enabled by TencentOS tiny

#define TOS_CFG_PWR_MGR_EN              0u		// Configure whether TencentOS tiny turns on peripheral power management module

#define TOS_CFG_TICKLESS_EN             0u		// Configure Tickless low power module switch

#define TOS_CFG_SEM_EN                  1u		// Configure whether the semaphore module is enabled by TencentOS tiny

#define TOS_CFG_TASK_STACK_DRAUGHT_DEPTH_DETACT_EN      1u	// Configure whether task stack depth detection is enabled for TencentOS tiny

#define TOS_CFG_FAULT_BACKTRACE_EN      0u		// Configure whether TencentOS tiny enables exception stack backtracking

#define TOS_CFG_IDLE_TASK_STK_SIZE      128u	// Configure the TencentOS tiny idle task stack size

#define TOS_CFG_CPU_TICK_PER_SECOND     1000u	// Configure the tick frequency of TencentOS tiny

#define TOS_CFG_CPU_CLOCK               (SystemCoreClock)	// Configure TencentOS tiny CPU frequency

#define TOS_CFG_TIMER_AS_PROC           1u		// Configure whether TIMER is configured as function mode

#endif

3, MDK project group directory and header file settings

1. Add group directory

• tos/arch
• tos/kernel
• tos/cmsis_os
• tos/config
  

2. Add tos/arch group file

3. Add tos/kernel grouping file

4. Add TOS / CMSIS? OS group file

5. Add tos/config group file

6. Add header file path

• Add the header file path as follows
  

4, Modify MDK source code and create TencentOS tiny task

1. Modify stm32f4xx? It. C interrupt configuration file

• Add the following code

/* USER CODE BEGIN Includes */
#include "tos_k.h"
/* USER CODE END Includes */

• Modify the PendSV_Handler function
  

__weak void PendSV_Handler(void)
{
  /* USER CODE BEGIN PendSV_IRQn 0 */

  /* USER CODE END PendSV_IRQn 0 */
  /* USER CODE BEGIN PendSV_IRQn 1 */

  /* USER CODE END PendSV_IRQn 1 */
}

• Modify systick'u handler function

void SysTick_Handler(void)
{
  /* USER CODE BEGIN SysTick_IRQn 0 */

  /* USER CODE END SysTick_IRQn 0 */
  HAL_IncTick();
  /* USER CODE BEGIN SysTick_IRQn 1 */
	if (tos_knl_is_running())
	{
		tos_knl_irq_enter();
		tos_tick_handler();
		tos_knl_irq_leave();
	}
  /* USER CODE END SysTick_IRQn 1 */
}

2. Create a new task in the main.c function

• The source code of main.c is as follows

/* USER CODE BEGIN Header */
