想让maix cube运行play_wav这个实例,io口应该怎么改啊 |
from fpioa_manager import * from Maix import I2S, GPIO import audio ########### settings ############ WIFI_EN_PIN = 8 # AUDIO_PA_EN_PIN = None # Bit Dock and old MaixGo AUDIO_PA_EN_PIN = 32 # Maix Go(version 2.20) # AUDIO_PA_EN_PIN = 2 # Maixduino # disable wifi fm.register(WIFI_EN_PIN, fm.fpioa.GPIO0, force=True) wifi_en = GPIO(GPIO.GPIO0, GPIO.OUT) wifi_en.value(0) # open audio PA if AUDIO_PA_EN_PIN: fm.register(AUDIO_PA_EN_PIN, fm.fpioa.GPIO1, force=True) wifi_en = GPIO(GPIO.GPIO1, GPIO.OUT) wifi_en.value(1) # register i2s(i2s0) pin fm.register(34, fm.fpioa.I2S0_OUT_D1, force=True) fm.register(35, fm.fpioa.I2S0_SCLK, force=True) fm.register(33, fm.fpioa.I2S0_WS, force=True) # init i2s(i2s0) wav_dev = I2S(I2S.DEVICE_0) # init audio player = audio.Audio(path="/sd/6.wav") player.volume(40) # read audio info wav_info = player.play_process(wav_dev) print("wav file head information: ", wav_info) # config i2s according to audio info wav_dev.channel_config(wav_dev.CHANNEL_1, I2S.TRANSMITTER, resolution=I2S.RESOLUTION_16_BIT, cycles=I2S.SCLK_CYCLES_32, align_mode=I2S.RIGHT_JUSTIFYING_MODE) wav_dev.set_sample_rate(wav_info[1]) # loop to play audio while True: ret = player.play() if ret == None: print("format error") break elif ret == 0: print("end") break player.finish() |
