打开ESP-IDF example界面,找到i2s_adc_dac例程: 图2 example i2s_adc_dac 点击 使用例程i2s_adc_dac创建项目就可以了。 该示例使用I2S控制ADC采样以及控制DAC数据流输出;程序首先会使用ADC采样音频,接着通过DAC回放录制的音频,最后播放项目中的音频文件,不断循环。 二、部分函数 部分I2S ADC相关库函数。 /** *...
在static void IRAM_ATTR i2s_intr_handler_default(void *arg)中 在if ((status & I2S_INTR_OUT_EOF) && p_i2s->tx) 中i2s_tx_count++; 在if ((status & I2S_INTR_IN_SUC_EOF) && p_i2s->rx) 中i2s_rx_count++; 然后在examples\peripherals\i2s\i2s_adc_dac的main中注释了xTaskCreate(adc_read...

I basically copied , compiled and ran the example in i2s_adc_dac however, I hear no audio at the end. I see printed DAC values in the console as is expected but i only hear white noise in my earphones. From the example instructions, I understood I could directly connect my earphones'...
I know this post is quite old, but i have the same problem. I am using esp-idf version 4.1 and i can't get the i2s_adc_dac-example to work. Whenever the sample frequency is over 5 kHz the i2s_read()-Function returns only zeros. Is there any known solution for this problem?3...

Re: i2s_adc_dac to generate .wav fileby ESP_Sprite » Thu Mar 01, 2018 1:18 am Not really, but in theory you could esptool.py to extract the data on the partition where the sound was recorded, then use a program like Sox to convert from raw data to wav. Or you could modify...
