stm32经济实惠,But its use is not as goodarduinoso convenient,Always get a downloaderst-linkOr have one toousb转ttl的ch34或者lp2002converter is connected,一个“痣”,麻烦！

stm32It is used very frequently in many small projects,Perhaps many people's embedded entry starts fromstm32开始,Here we take a look atproteushow to simulate.

对于初学者而言,We still want to be moreproteusIt's better to simulate it,No need to sell hardware,No need to buy a downloader, etc.Below we describe how to do it！

一、在prtoteusDraw a schematic diagram

我们做一个blink程序,Simple is simpler,But ok,容易看明白

二、写代码

#include "stm32f1xx_hal.h"


void SystemClock_Config(void);
void Error_Handler(void);
static void MX_GPIO_Init(void);


int main(void)
{
    


  HAL_Init();

  SystemClock_Config();


  MX_GPIO_Init();


  while (1)
  {
    
	HAL_GPIO_TogglePin(Ld2_GPIO_Port, Ld2_Pin); //Toggle LED
	HAL_Delay(1000); //Delay 1 Seconds

  }


}

/** System Clock Configuration */
void SystemClock_Config(void)
{
    

  RCC_OscInitTypeDef RCC_OscInitStruct;
  RCC_ClkInitTypeDef RCC_ClkInitStruct;

  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;
  RCC_OscInitStruct.HSIState = RCC_HSI_ON;
  RCC_OscInitStruct.HSICalibrationValue = 16;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI_DIV2;
  RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL4;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    
    Error_Handler();
  }

  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
                              |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV2;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV4;
  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV2;
  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK)
  {
    
    Error_Handler();
  }

  HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq()/1000);

  HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);

  /* SysTick_IRQn interrupt configuration */
  HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0);
}


static void MX_GPIO_Init(void)
{
    

  GPIO_InitTypeDef GPIO_InitStruct;


  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOD_CLK_ENABLE();
  __HAL_RCC_GPIOA_CLK_ENABLE();
  __HAL_RCC_GPIOB_CLK_ENABLE();


  GPIO_InitStruct.Pin = GPIO_PIN_13|GPIO_PIN_14|GPIO_PIN_15|GPIO_PIN_0 
                          |GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3|GPIO_PIN_4 
                          |GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7|GPIO_PIN_8 
                          |GPIO_PIN_9|GPIO_PIN_10|GPIO_PIN_11|GPIO_PIN_12;
  GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
  HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);


  GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_2;
  GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
  HAL_GPIO_Init(GPIOD, &GPIO_InitStruct);


  GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3 
                          |GPIO_PIN_4|GPIO_PIN_6|GPIO_PIN_7|GPIO_PIN_8 
                          |GPIO_PIN_9|GPIO_PIN_10|GPIO_PIN_11|GPIO_PIN_12 
                          |GPIO_PIN_13|GPIO_PIN_14|GPIO_PIN_15;
  GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);


  GPIO_InitStruct.Pin = Ld2_Pin;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
  HAL_GPIO_Init(Ld2_GPIO_Port, &GPIO_InitStruct);


  GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_10 
                          |GPIO_PIN_11|GPIO_PIN_12|GPIO_PIN_13|GPIO_PIN_14 
                          |GPIO_PIN_15|GPIO_PIN_3|GPIO_PIN_4|GPIO_PIN_5 
                          |GPIO_PIN_6|GPIO_PIN_7|GPIO_PIN_8|GPIO_PIN_9;
  GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
  HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);


  __HAL_AFIO_REMAP_PD01_ENABLE();


  HAL_GPIO_WritePin(Ld2_GPIO_Port, Ld2_Pin, GPIO_PIN_RESET);

}


void Error_Handler(void)
{
    
  
  while(1) 
  {
    
  }
  
}

#ifdef USE_FULL_ASSERT


void assert_failed(uint8_t* file, uint32_t line)
{
    


}

#endif

三、编译与运行

At first we may encounter compiler errors
The selected compiler ‘GCC for ARM’ is not installed.
Compilation failed. Check the Project Settings.

1、安装编译器

点击对GCC for arm后的download,It will pop up after the detection is completeYaGArto的安装界面,Continue to check after installation

Downloaded and stored in proteus的安装目录下的data的downloads下

2、配置编译器

安装好后,再次点击downloadIt will automatically install just nowyagarto配置进来,或者点击下面的check也可以

运行效果

It's often difficult to start things off,The difficulty of embedded development lies in the construction of the environment,There are many children's shoes that are just beginning to die on the way of environmental configuration,Difficulty in that stringhello world,The difficulty lies in the flickering oneLED灯blink程序.

I hope this blog post will help you replay the stumbling block of this starting point,从此一帆风顺~~
