WM8960 与 pigpiod 的冲突是要命的,无法使用软串口了?
使用 pigpiod 命令 或是 pigpiod -t 0 然后启动软串口,其中 .wave_send_once() 如下描述 """ Transmits the waveform with id wave_id. The waveform is sent once.
NOTE: Any hardware PWM started by [*hardware_PWM*] will
be cancelled.
wave_id:= >=0 (as returned by a prior call to [*wave_create*]).
Returns the number of DMA control blocks used in the waveform.
...
cbs = pi.wave_send_once(wid)
...
"""
如果正在播放音乐,执行此命令会当即停止,即便释放后也无法正确的播放音频,求解决!
