ADC and clock configuration
Posted: Thu Jul 16, 2015 4:48 amHi there,
I'm trying to sample a signal with ESP8266s ADC. Does someone knows how to configure the ADC? I mean, is it enough to just call system_adc_read()? I read about vdd33_const in esp_init_data_default.bin, but I'm a bit confused about that...
Moreover, I measured 2.6kHz sample rate, that is not so high...there is a way to increase it? Is it somehow related to system clock? Actually how much is the system clock and how could I change it??
