Hello,
I'm playing beep sound using pwm1 (timer1).
The onSound() starts beep sound.
The disableBuzzer() terminates pwm1.
The handler_buzzer() selects continuous sound playback or pwm1 termination.
- Abnormal condition with log message
-
The "buzzer stop" does not occur and the watchdog reset(2 sec) occurs intermittently.
-
Even if "buzzer stop" is output, there is no buzzer sound and watchdog reset (2 sec) occurs intermittently.
I am wondering if there is a problem with the code. I use nrf51822/SDK 12.1.0. I need help.
thanks.
