RTC Marco callbacks

Anonymous · ‎Dec 19, 2016

Hi,

I got a problem about RTC marco callbacks.

When I read the parameters of RTC ,it was working.But I want RTC do something every second.So I fininshed some code according to CAG 6.1.6

code of user code is listed below

TaskHandle_t rtc_task_handle;

void RTC_6813_EverySecondHandler_Callback(void)
{
    if(rtc_task_handle!=NULL)
    {
        vTaskResume(rtc_task_handle);
    };
}

void rtc_test_task(void *pvparameter)
{
    uint8_t data;

    for(;;)
    {

        vTaskSuspend(xTaskGetCurrentTaskHandle());
        data=RTC_6813_ReadSecond();
        uart_485_send_block(&data,1);
    };
}

code of cyapicallbacks.h is listed below

#ifndef CYAPICALLBACKS_H
#define CYAPICALLBACKS_H

    /*Define your macro callbacks here */
    /*For more information, refer to the Macro Callbacks topic in the PSoC Creator Help.*/

#define RTC_6813_EVERY_SECOND_HANDLER_CALLBACK

void RTC_6813_EverySecondHandler_Callback(void);

#endif /* CYAPICALLBACKS_H */

code of startup is listed below

    RTC_6813_Start();
    RTC_6813_EnableInt();
    xTaskCreate(rtc_test_task,"rtctest",configMINIMAL_STACK_SIZE,NULL,1,&rtc_task_handle);

Other tasks of system are fine.The callback function of RTC was not invoked!

From the datasheet (component) -

General Description

The Real-Time Clock (RTC) component provides accurate time and date information for the
system. The time and date are updated every second based on a one pulse per second interrupt
from a 32.768-kHz crystal. Clock accuracy is based on the crystal provided and is typically
20 ppm.

Here is a series of projects with wakeup that you can look at -
