About CY8CKIT-042-BLE-A bluetooth low energy pioneer kit?--About Code ？-Thanks

Robin_Peng · ‎Apr 23, 2020

Hi Sir.

I have some basic questions,The development kit I use is CY8CKIT-042-BLE-A. The chip I use is CY8C4247LQI-BL463.

1、I use the alarm function in RTC. When the alarm time is reached, it is interrupted and cleared after interruption, but why does the flag state of this interruption never change when I debug？alarmFLag is 0 at the beginning, 1 after the interrupt, and then always 1

Thanks

Are you sure the "AlarmFlag = 0" in the last picture is executed when you expect the AlarmFlag value go back to 0?

Hi Sir,

AlarmFlag is 0 when it is initially initialized. When an interrupt occurs, AlarmFlag becomes 1. After that, AlarmFlag is always in the state of 1, even if it is cleared to 0 in the main function, the program is set to 1 hour and 58 minutes alarm.The alarm code is modified according to RTC_P4_WDT_Example.Thanks.

Hi Sir,

I am sure the "AlarmFlag = 0" in the last picture is executed when I expect the AlarmFlag value go back to 0.I stepped through the debugging.

Hi RoPe_2386886,

I checked the code example RTC_P4_WDT_Example and found that the alarmFlag is set once the execution enters the "AlarmIsrHandler" function. The code example worked correctly and the alarm was triggered which led to the setting of alarmFlag to 0 inside the if statement in the main(). The issue with your code might be that the execution is not entering the AlarmIsrHandler due to some reason. Please check this accordingly in your project.

Also, Please check if the clock_f variable is preventing the setting of the alarmFlag since it is used in your code for the condition of the if statement. I have attached my project where I modified the alarm time to check the working of the code example. Please go through it once and let us know if you are facing the issue again.

Best Regards,

Aashita
