Hello,

I'm using FreeRTOS and MSP432, but I'm receiving an error when I try to use the "xSemaphoreHandle". I would like to know whether anyone can help me?

CODE:

#include "dataStorageTask.h"
#include "semphr.h"
#include "FreeRTOS.h"

xSemaphoreHandle semaphoreSignaling =0;
...

    Hi,

    when using the xSemaphore functions you still use the normal SemaphoreHandle.

    e.g.

    SemaphoreHandle_t xSemaphore;

void vATask( void * pvParameters )

{

  /* Create a mutex type semaphore. */

  xSemaphore = xSemaphoreCreateMutex();

  if( xSemaphore != NULL )

  {

      /* The semaphore was created successfully and

      can be used. */

  }

}

    See also the FreeRTOS documentation:

    https://www.freertos.org/CreateMutex.html

    Regards,

    Stefan
