[Bug] audio_pwm_hardware.c compile error #19097

Closed boulevard-h closed 1 year ago

boulevard-h commented 1 year ago

Describe the Bug

I'm adding a piezo buzzer to my keyboard using stm32f103c8t6 mcu. According to the qmk docs, I my code about AUDIO is: in rules.mk:

AUDIO_ENABLE = yes
AUDIO_DRIVER = pwm_hardware

in config.h:

#define AUDIO_PIN A8
#define AUDIO_PWM_DRIVER PWMD1
#define AUDIO_PWM_CHANNEL 1
#define AUDIO_CLICKY

when I compile my program, error occurs:

Not really a bug, more the failure to correctly configure the dependent hardware https://docs.qmk.fm/#/audio_driver?id=pwm-hardware.
