This is the range of values that I have read from the ADC.
The description reads my ADC using: Read the value from ADC pin, represented as a 32-bit signed, right-aligned value.
This is a 'resolution'-bit value, sign-extended to 32 bits. If the vplus signal is below the vminus signal, the result will be negative. If the vplus signal is above the vminus signal, the result will be positive. If continous scanning is disabled, this will block while a conversion is performed on the selected channel, then return the result. Depending on the ADC speed this function may block for some time. If continuous scanning is enabled, this will return the value from the most recent conversion of the specified channel (if called shortly after enabling continuous scanning it may block until at least one conversion has been performed on this channel).
