Could anyone help me build my STM32F1 HAL project?

I have a minimum STM32F103ZET6 system board with. I have downloaded STM32CubeF1(Version 1.2.0) package. I build a simple project, which just blink a led, and I compile it with no error/warning. The main.c source code is shown below

#include''stm32f1xx_hal.h''#include''stm32f1xx_hal_gpio.h''#include''stm32f1xx_hal_rcc.h''#include''stm32f1xx_hal_rcc_ex.h''#include''stdint.h''void m_delay(volatile uint32_t m_time){  while(m_time > 0){    m_time--;  }}void SystemClock_Config(){  RCC_ClkInitTypeDef Clk_InitStructure = {0};  RCC_OscInitTypeDef Osc_InitStructure = {0};  Osc_InitStructure.OscillatorType  = RCC_OSCILLATORTYPE_HSE;   Osc_InitStructure.HSEState        = RCC_HSE_ON;   Osc_InitStructure.HSEPredivValue    = RCC_HSE_PREDIV_DIV1;   Osc_InitStructure.PLL.PLLState    = RCC_PLL_ON; */  Osc_InitStructure.PLL.PLLSource   = RCC_PLLSOURCE_HSE;   Osc_InitStructure.PLL.PLLMUL      = RCC_PLL_MUL9;   if (HAL_RCC_OscConfig(&Osc_InitStructure)!= HAL_OK)  {    /* Initialization Error */    while(1);   }  /* Select PLL as system clock source and configure the HCLK, PCLK1 and PCLK2      clocks dividers */  Clk_InitStructure.ClockType = (RCC_CLOCKTYPE_SYSCLK | RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2);  Clk_InitStructure.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;  Clk_InitStructure.AHBCLKDivider = RCC_SYSCLK_DIV1;  Clk_InitStructure.APB2CLKDivider = RCC_HCLK_DIV1;  Clk_InitStructure.APB1CLKDivider = RCC_HCLK_DIV2;    if (HAL_RCC_ClockConfig(&Clk_InitStructure, FLASH_LATENCY_2)!= HAL_OK)  {    /* Initialization Error */    while(1);   }}int main(){  HAL_Init();  SystemClock_Config();  __HAL_RCC_GPIOG_CLK_ENABLE();  GPIO_InitTypeDef GPIO_InitStructure;  GPIO_InitStructure.Pin = GPIO_PIN_14;  GPIO_InitStructure.Mode = GPIO_MODE_OUTPUT_PP;  GPIO_InitStructure.Pull = GPIO_PULLUP;  GPIO_InitStructure.Speed = GPIO_SPEED_HIGH;  HAL_GPIO_Init(GPIOG, &GPIO_InitStructure);  while(1){    HAL_GPIO_WritePin(GPIOG, GPIO_PIN_14, 1);    HAL_Delay(500);    HAL_GPIO_WritePin(GPIOG, GPIO_PIN_14, 0);    HAL_Delay(500);  }  return 0;}But it didn't work well. The pin output HIGH and didn't change its value. It looks like the program block at  ''HAL_GPIO_WritePin(GPIOG, GPIO_PIN_14, 1)''. Even I change the HAL_Delay() to the function I write m_delay(), it also can be blocked.  So what wrong with my code?

Hi yuzhou.huang,

I suggest you:1- Debug your code as the problem may be caused by clock configuration code for example, not GPIO related function2- Have a look to the example STM32Cube_FW_F1_V1.2.0\Projects\STM32F103RB-Nucleo\Examples\GPIO\GPIO_IOToggle implementing similar functionality as what you want.3- Use the STM32CubeMX tool to generate initialization project to which you may add your own code.-Mayla-

If the external clocks, or internal PLL, don't start correctly you're going to fall into one of the while(1) tar pits. Add code to identify where it's stuck, output via a GPIO/LED or USART.

Hello,

HAL_Delay(500); requires SysTick_Handler() did you implement it? Otherwise the tick counter doesn't increment and you are stall in HAL_Delay().

void SysTick_Handler(void)
{
HAL_IncTick();
}
