Thank you for your reply.
With reference to BeastH7 I wrote hwdef.dat as follows.
PC13 BUZZER OUTPUT GPIO (80) LOW
define HAL_BUZZER_PIN 80
define HAL_BUZZER_ON 1
define HAL_BUZZER_OFF 0
I set the parameters that seem to be related to an active buzzer as follows.
NTF_BUZZ_ON_LVL, 1 (I also tried 0,1)
NTF_BUZZ_TYPES, 0 (I also tried 0,1,2)
NTF_BUZZ_VOLUME, 100 (I also tried 0,50,100)
In addition, I also tried following to make “LostCopterSound” sound by ch7 of RC.
But my active buzzer doesn’t make any sound.
Is there anything I have forgotten?
Is it possible to sound an active buzzer on port PC13 that does not have a timer function?
Of course, if I upload Betaflight firmware to FC, an active buzzer will beep on PC13 without any problems.
I would appreciate any additional information.
