ADC

Function Description

Analog to digital conversion

Init in Pin Set the sampling channel pin

set width Set the sampling width

set atten Set attenuation on the input of the ADC * ADC.ATTN_0DB: 0dB attenuation, gives a maximum input voltage of 1.00v - this is the default configuration * ADC.ATTN_2_5DB: 2.5dB attenuation, gives a maximum input voltage of approximately 1.34v * ADC.ATTN_6DB: 6dB attenuation, gives a maximum input voltage of approximately 2.00v * ADC.ATTN_11DB: 11dB attenuation, gives a maximum input voltage of approximately 3.6v
