【CMSIS】osThreadCreate

1 osThreadDef

osThreadDef(defaultTask, StartDefaultTask, osPriorityNormal, 0, 128);

2 osThreadCreate

osThreadId defaultTaskHandle;
defaultTaskHandle = osThreadCreate(osThread(defaultTask), NULL);
osKernelStart();

3 StartDefaultTask

Explorer STM32F4示例：

void StartDefaultTask(void const * argument)
{
	// 开启GBIOF时钟
	*(unsigned int*)(RCC_BASE + 0x30) |= 1 << 5;
	// 输出模式
	*(unsigned int*)(GPIOF_BASE + 0x00) = 0x01 << 18;
	// 推挽输出
	*(unsigned int*)(GPIOF_BASE + 0x04) = 0 << 9;
	// 输出速度50MhZ
	*(unsigned int*)(GPIOF_BASE + 0x08) = 0x10 << 18;
	// 上拉电阻
	*(unsigned int*)(GPIOF_BASE + 0x0C) = 0x01 << 18;

  for(;;)
  {
		// 端口输出0，灯亮
		*(unsigned int*)(GPIOF_BASE + 0x14) = 0 << 9;
		osDelay(1000);
		// 端口输出1，灯灭
		*(unsigned int*)(GPIOF_BASE + 0x14) = 1 << 9;
		osDelay(1000);
  }
