WAV文件解析是本方案的关键步骤。WAV文件格式类似于bmp文件，由文件头和音频数据两部分组成。解析文件头可获取到I2S所需的参数，如采样率、量化位宽和通道数。文件头共有44个字节，包含文件大小、格式类型、通道数等信息。解析文件时，需根据提取信息更新I2S配置，以实现音频播放。在ESP32_IDF的例程中，提...

driver. The rest of the application code has not changed. Hardware has not changed-- audio is played through a MAX98357A. The only thing that has changed in code is the function that configures the i2s driver and the function that uses i2s_channel_write() instead of i2s_write(). Any ...
i2s_write应该用来代替i2s_write_bytes和i2s_push_sample,这是不赞同的。 i2s_read应该用来代替i2s_read_bytes和i2s_pop_sample,这是不赞同的 (esp_ble_gattc_open())remote_addr_type添加了一个新参数esp_ble_gattc_open() 修改ESP_GATTS_ADD_CHAR_DESCR_EVTBLE GATTS事件的char_uuid参数,将此事件的参数重...
