Hi everyone,

I am trying to learn the CMSIS-RTOS RTX. I have experience in FreeRTOS. I am trying to test this example: https://www.keil.com/pack/doc/CMSIS/RTX/html/_example_r_t_x__tutorial.html&sharpRTX_Tutorial_SVCBut my hardware is a STM32F107VC. it's not a

 STM32F429. the test program compiles fine but I can't get the test program work fine: This is my code, Iam using the pin PC13 as interrupt line:

/*----------------------------------------------------------------------------

   CMSIS-RTOS 'main' function template

 *---------------------------------------------------------------------------*/

&sharpdefine osObjectsPublic                     // define objects in main module

&sharpinclude ''osObjects.h''                      // RTOS object definitions

&sharpinclude ''stm32f10x.h''

&sharpinclude ''led_open107v.h''

//&sharpinclude ''joystick_open107v.h''

void led_Thread1(void const *argument);

void led_Thread2(void const *argument);

void exti_Thread(void const *argument);

void __svc(1) init_EXTI(void);             //Define the EXTI initializing code as a supervisor function

void UserKey_Configuration(void);

void configInterrupt(void);

osThreadDef(led_Thread1, osPriorityNormal, 1, 0);

osThreadDef(led_Thread2, osPriorityNormal, 1, 0);

osThreadDef(exti_Thread, osPriorityAboveNormal, 1, 0);

osThreadId T_led_ID1;

osThreadId T_led_ID2;   

osThreadId T_exti_ID;

void exti_Thread(void const *argument) {

  for (;;) {

    osSignalWait(0x01, osWaitForever);

    LED_On(1);

    osDelay(500);

    LED_Off(1);

  }

}

void led_Thread1(void const *argument) {

  for (;;) {

    osSignalWait(0x01, osWaitForever);

    LED_Off(0);

  }

}

void led_Thread2(void const *argument) {

  for (;;) {

    LED_On(0);

    osDelay(500);

    osSignalSet(T_led_ID1, 0x01);

    osDelay(500);

  }

}

/*

main: initialize and start the system

*/

int main(void) {

  osKernelInitialize();

init_EXTI(); //initialize the external interrupts

LED_Initialize();

  T_led_ID1 = osThreadCreate(osThread(led_Thread1), NULL);

  T_led_ID2 = osThreadCreate(osThread(led_Thread2), NULL);

  T_exti_ID = osThreadCreate(osThread(exti_Thread), NULL);

  osKernelStart(); // start thread execution                

}

void __svc(1) init_EXTI (void);

void __SVC_1(void) {

  UserKey_Configuration();

configInterrupt();

}

/*----------------------------------------------------------------------------

   EXTI interrupt handler

 *---------------------------------------------------------------------------*/

void EXTI15_10_IRQHandler(void) {

/* Check if EXTI_Line13 is asserted */

if(EXTI_GetITStatus(EXTI_Line13) != RESET) {

/* [EXTI15_10_IRQHandler] EXTI_Line13 is asserted. KeyUser PC13 */

/* We need to clear line pending bit manually */

osSignalSet(T_exti_ID, 0x01);   

EXTI_ClearITPendingBit(EXTI_Line13);

}

}

void UserKey_Configuration(void) {

GPIO_InitTypeDef GPIO_InitStructure;

  /* GPIOC Port Clock Enable */

  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);

/* User key PC13*/

GPIO_InitStructure.GPIO_Pin =  GPIO_Pin_13;

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;

GPIO_Init(GPIOC, &GPIO_InitStructure);

}

void configInterrupt(void) {

EXTI_InitTypeDef EXTI_InitStructure;  /* EXTI structure to init EXTI */

  NVIC_InitTypeDef NVIC_InitStructure; /* NVIC structure to init NVIC Controller */

/* keyUser PC13 */

GPIO_EXTILineConfig(GPIO_PortSourceGPIOC, GPIO_PinSource13); /* Connect EXTI line to button. Port C and pin 13 */

EXTI_InitStructure.EXTI_Line = EXTI_Line13; /* Configure Button port C and pin 13, EXTI line */

EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt; /* Select interrupt mode */

EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling; /* Generate interrupt on rising edge */

EXTI_InitStructure.EXTI_LineCmd = ENABLE; /* Enable EXTI line */

EXTI_Init(&EXTI_InitStructure); /* Send values to registers */

/* Configure NVIC */

NVIC_InitStructure.NVIC_IRQChannel = EXTI15_10_IRQn; /* Select NVIC channel to configure */

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x0F; /* Set priority to lowest */

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x0F; /* Set subpriority to lowest */

NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; /* Enable IRQ channel */

NVIC_Init(&NVIC_InitStructure); /* Update NVIC registers */

/* End keyuser PC13 */

}

What can I be doing wrong?

Thank you so much, Best regards.
