Hello,
Here is my program:
int32_t socket; uint8_t *sendbuf; void Time3(void){ TIM_TimeBaseInitTypeDef TimeStruct; NVIC_InitTypeDef nvicStructure; NVIC_PriorityGroupConfig(NVIC_PriorityGroup_3); nvicStructure.NVIC_IRQChannel = TIM3_IRQn; nvicStructure.NVIC_IRQChannelPreemptionPriority =1; nvicStructure.NVIC_IRQChannelSubPriority = 0; nvicStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&nvicStructure); RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3,ENABLE); TimeStruct.TIM_Prescaler=35; TimeStruct.TIM_Period=200; ///200=100us TimeStruct.TIM_ClockDivision=TIM_CKD_DIV1; TimeStruct.TIM_CounterMode= TIM_CounterMode_Up ; TIM_TimeBaseInit(TIM3, &TimeStruct); TIM_Cmd(TIM3, ENABLE); TIM_ITConfig(TIM3,TIM_IT_Update,ENABLE); } /*########################################### ##############Main Function################## ###########################################*/ void SetSCK(){ socket = netUDP_GetSocket(udp_cb_func); if (socket >= 0) { netUDP_Open(socket,0); netUDP_SetOption (socket, netUDP_OptionTTL, 20); } } int main (void){ CLOCK(); GPIO_SetBits(GPIOA,GPIO_Pin_5); LongDelay(); netInitialize(); LongDelay(); Time3(); GPIO_ResetBits(GPIOA,GPIO_Pin_5); do { osDelay(500U); netIF_GetOption(NET_IF_CLASS_ETH | 0, netIF_OptionIP4_Address, (uint8_t *)&addr, sizeof (addr)); } while (addr == 0U); SetSCK(); while (1) { if(Alarm==1) { Alarm=0; Ethers(); } if(CheckAlarm>2) { netUDP_Close (socket); netUDP_ReleaseSocket (socket); SetSCK(); CheckAlarm=0; } } } void Ethers(void){ NET_ADDR addrUDP={ NET_ADDR_IP4, 5022, 192, 168,1,10}; if(socket>=0){ CheckAlarm=0; Data(); sendbuf = netUDP_GetBuffer (Ether.Size); memcpy (sendbuf, MSG, Ether.Size); State=netUDP_Send (socket,&addrUDP,sendbuf,Ether.Size); } void TIM3_IRQHandler(){ CheckAlarm=CheckAlarm+1; Alarm=1; TIM_ClearITPendingBit(TIM3, TIM_IT_Update); }
But after some seconds which it works fine, it jumps to os_idle_demon function in RTX.
/// \brief The idle demon is running when no other thread is ready to run void os_idle_demon (void) { for (;;) { /* HERE: include optional user code to be executed when no thread runs.*/ } }
I don't know why it goes to this function which disables my MCU operation. I am a newbie to debugging to trace this problem (why this happens before going to this sleep function).
Thanks, One more question.
As I checked this function:
void Ethers(void){ uint8_t *sendbuf; NET_ADDR addrUDP={ NET_ADDR_IP4, 5022, 192, 168,1,10}; if(socket>=0){ CheckAlarm=0; Data(); sendbuf = netUDP_GetBuffer (Ether.Size); if(sendbuf!=NULL) { CheckAlarm=0; memcpy (sendbuf, MSGETH, Ether.Size); State=netUDP_Send (socket,&addrUDP,sendbuf,Ether.Size); } }
Takes about(70 MicroS) to execute for all commands. By considering sending 70us and resting for 100us after that, can MCU transmit a UDP package each 100us or RTOS can't handle this situation (STM32f10x,DP8384)
Here is my final code:
int32_t socket; uint8_t *sendbuf; void Time3(void){ TIM_TimeBaseInitTypeDef TimeStruct; NVIC_InitTypeDef nvicStructure; NVIC_PriorityGroupConfig(NVIC_PriorityGroup_3); nvicStructure.NVIC_IRQChannel = TIM3_IRQn; nvicStructure.NVIC_IRQChannelPreemptionPriority =1; nvicStructure.NVIC_IRQChannelSubPriority = 0; nvicStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&nvicStructure); RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3,ENABLE); TimeStruct.TIM_Prescaler=35; TimeStruct.TIM_Period=200; ///200=100us TimeStruct.TIM_ClockDivision=TIM_CKD_DIV1; TimeStruct.TIM_CounterMode= TIM_CounterMode_Up ; TIM_TimeBaseInit(TIM3, &TimeStruct); TIM_Cmd(TIM3, ENABLE); TIM_ITConfig(TIM3,TIM_IT_Update,ENABLE); } /*########################################### ##############Main Function################## ###########################################*/ void job3 (void const *argument) { netInitialize(); } osThreadDef(job3, osPriorityAboveNormal, 1, 0); void SetSCK(){ socket = netUDP_GetSocket(udp_cb_func); if (socket >= 0) { netUDP_Open(socket,0); netUDP_SetOption (socket, netUDP_OptionTTL, 20); } } int main (void){ CLOCK(); GPIO_SetBits(GPIOA,GPIO_Pin_5); LongDelay(); osKernelInitialize (); osThreadCreate (osThread(job3),NULL); osKernelStart (); LongDelay(); Time3(); GPIO_ResetBits(GPIOA,GPIO_Pin_5); do { osDelay(500U); netIF_GetOption(NET_IF_CLASS_ETH | 0, netIF_OptionIP4_Address, (uint8_t *)&addr, sizeof (addr)); } while (addr == 0U); SetSCK(); while (1) { if(Alarm==1) { Alarm=0; Ethers(); } } } void Ethers(void){ NET_ADDR addrUDP={ NET_ADDR_IP4, 5022, 192, 168,1,10}; if(socket>=0){ CheckAlarm=0; Data(); sendbuf = netUDP_GetBuffer (Ether.Size); memcpy (sendbuf, MSG, Ether.Size); State=netUDP_Send (socket,&addrUDP,sendbuf,Ether.Size); } void TIM3_IRQHandler(){ CheckAlarm=CheckAlarm+1; Alarm=1; TIM_ClearITPendingBit(TIM3, TIM_IT_Update); }
My program hangs after some seconds before using a thread for "netInitialize();" function. After adding a new thread for netInitialize() (Job3) it shows me this fault window:
In my point of view, my STM32f107 and DP8384 communication for sending each 100us a UDP package have a problem and it causes that the netInitialize(); halted. because I can't see any other problems.
Halted just means that you've stopped (ie, "Halted") it in the debugger!
