打开计时器驱动程序出现问题

嗨，社区，我想使用TMRY5。我是按照“入门”的建议来做的。但是当我想在“App.c”中打开TMRIX驱动程序时，处理程序“AppDATA，TMR.SCRISHORH”仍然处于状态“DrvHAdLeLead无效”，因为我不能到达激活“DrvtTMRMARLARM寄存器”并启动TMR的代码部分，我使用的是HyV2.02BMPLAB X IDE V.3.55 xC32 V1.42Sype。在“App.h”中：“App.c”：然后在“AppStices”中进一步：什么可能出错？谢谢你的支持，亨利

    Hi Community,
I want to use the TMR_5. I`m following the advises in the "Getting Started". But the when I want to open the TMR_Driver in "app.c", the handler "appData.TMR_ScrRefresh" is still in status "DRV_HANDLE_INVALID", because I cannot reach the code part which is activating the "DRV_TMR_AlarmRegister" and starting the TMR.

I`m using
Harmony v2.02b
MPLAB X IDE v.3.55
XC32 v1.42





In "system_config.h":
#define TMR5_ForScrRefresh DRV_TMR_INDEX_0
#define TMR5_ForScrRefresh_IS_PERIODIC true
#define TMR5_ForScrRefresh_PERIOD 0xFE51
#define TMR5_ForScrRefresh_COUNT_MAX 6

In "app.h":
typedef struct
{
    /* The application's current state */
    APP_STATES state;

    /* TODO: Define any additional data used by the application. */
   
    /* TMR5 driver handler for Scr refresh*/
    DRV_HANDLE TMR_ScrRefresh;
    /* TMR5 cycle counter*/
    uint16_t TMR_ScrRefreshCount;

} APP_DATA;

In "app.c":
APP_DATA appData;
and
   appData.state = APP_STATE_INIT;
   appData.TMR_ScrRefresh = DRV_HANDLE_INVALID;
   appData.TMR_ScrRefreshCount = 0;
and then further in the "APP_Tasks":
void APP_Tasks ( void )
{

    /* Check the application's current state. */
    switch ( appData.state )
    {
        /* Application's initial state. */
        case APP_STATE_INIT:
        {
            appData.TMR_ScrRefresh = DRV_TMR_Open( TMR5_ForScrRefresh,
                DRV_IO_INTENT_EXCLUSIVE);
            if ( DRV_HANDLE_INVALID != appData.TMR_ScrRefresh )
            {
                DRV_TMR_AlarmRegister(appData.TMR_ScrRefresh,
                    TMR5_ForScrRefresh_PERIOD,
                    TMR5_ForScrRefresh_IS_PERIODIC,
                    (uintptr_t)&appData,
                    TMR5_ISR);
                DRV_TMR_Start(appData.TMR_ScrRefresh);
                appData.state = APP_STATE_IDLE;
            }
            
            bool appInitialized = true;
      
        
            if (appInitialized)
            {
            
                appData.state = APP_STATE_SERVICE_TASKS;
            }
            break;
        }

        case APP_STATE_SERVICE_TASKS:
        {
        
            break;
        }

        /* TODO: implement your application state machine.*/
        

        /* The default state should never be executed. */
        default:
        {
            /* TODO: Handle error in application's state machine. */
            break;
        }
    }
}

What could be wrong?

Thanks for support.
