Wangjialin	945d2e697c	driver(i2s): fix broken i2s adc mode ... 1. Move i2s reset code from i2s_stop to i2s_start. 2. add RTC API to set sw mode for ADC 3. add description for adc_power_always_on() 4. add lock for i2s dma and RTC ADC functions. 5. add ADC read task in example reported from bbs: https://esp32.com/viewtopic.php?f=13&t=3490&p=17522#p17522 reported from github: https://github.com/espressif/esp-idf/issues/1333 Also update some deprecated APIs for ADC.	2018-05-16 11:42:53 +08:00

Wangjialin	2fceec4d85	feature(I2S-ADC): add ADC mode for I2S. ... 1. Support built-in ADC for I2S. 2. Modify code of ADC, made no change to the original APIs. 3. Add APIs in I2S: esp_err_t i2s_set_adc_mode(adc_unit_t adc_unit, adc1_channel_t adc_channel); 4. Add I2S ADC/DAC example code. 5. add old-fashion definition to make it more compatible 6. replase spi_flash_ APIs with esp_partition_ APIs 7. add example of generating audio table from wav 8. change example sound	2017-09-14 13:24:08 +08:00
