where is the GPIO37 and GPIO38?

I need an 8-channel ADC, just GPIO32-39 can meet my needs, but GPIO37 and GPIO38 can't be found on the documentation. Where is the gpio 37 and 38?

Re: Use multiple sample rates simultaneously

I found a solution:

Code: Select all

	audio_element_info_t info;
	audio_element_getinfo(i2s_stream_reader, &info);
	info.sample_rates = 16000, info.channels = 1;
	audio_element_setinfo(i2s_stream_reader, &info);

Use multiple sample rates simultaneously

esp_audio_cfg_t cfg = { .in_stream_buf_size = 10 * 1024, .out_stream_buf_size = 6 * 1024, .evt_que = NULL, .resample_rate = 0, .hal = NULL, }; audio_hal_codec_config_t audio_hal_codec_cfg = AUDIO_HAL_ES8388_DEFAULT(); audio_hal_codec_cfg.i2s_iface.samples = AUDIO_HAL_16K_SAMPLES; cfg.hal = audio_ha...
