RTOS+LwIP Socket 不工作的问题
本人用RTOS创建了五个任务， 如下：/* RTOS 多任务创建调度机制 */
osThreadDef(TCPSOCKETSERVER, TCP_Socket_Server, osPriorityRealtime, 0, 512); 1
TCPSOCKETSERVERHandle = osThreadCreate(osThread(TCPSOCKETSERVER), NULL);
osThreadDef(STM32F4ADC, STM32F429_ADC1_Init, osPriorityNormal, 0, 512); 2
STM32F4ADCRHandle = osThreadCreate(osThread(STM32F4ADC), NULL);
osThreadDef(RTCCLOCKTIME, RTC_CLOCK_TIME, osPriorityNormal, 0, 512); 3
RTCCLOCKTIMEHandle = osThreadCreate(osThread(RTCCLOCKTIME), NULL);
osThreadDef(RTOSLEDTEST, RTOS_LED_TEST,osPriorityNormal, 0, 512); 4
RTOSLEDTESTHandle = osThreadCreate(osThread(RTOSLEDTEST), NULL);
osThreadDef(RTOSKEYEXIT, RTOS_KEY_EXIT, osPriorityNormal, 0, 512); 5
RTOSKEYEXITHandle = osThreadCreate(osThread(RTOSKEYEXIT), NULL);同时运行的时候， 2,3,4,5 工作正常，1 可以创建任务，只是无法Ping通，暂停2,3,4，5 单独执行1 ，就没问题，不知道这个问题出在哪里，很愚蒙
