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
