Ivan Grokhotkov	dec4a868d0	examples/ulp: disable pullup on GPIO15 to reduce current ... Also increase sampling frequency in ulp_adc example and update READMEs. Fixes https://github.com/espressif/esp-idf/issues/1108	2017-11-03 18:56:31 +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
