Hal_gpio_exit_callback

WebGPIO events can be mapped to an interrupt and assigned to a callback function. The callback function needs to be first registered and then the event needs to be enabled. The following snippet initializes GPIO pin P0_0 as an input pin. It registers a callback function and enables detection of a falling edge event to trigger the callback. Note Web好的，我可以回答这个问题。以下是一个简单的Python音乐播放器代码示例： ```python import pygame pygame.init() pygame.mixer.music.load("music.mp3") pygame.mixer.music.play() while pygame.mixer.music.get_busy(): continue ``` 这个代码使用了Pygame库来播放音乐。
