Скачать или смотреть Measuring Analog Voltages on Arduino using the Serial Wombat 4B chip's Analog Input pin mode

This video goes with the Serial Wombat analog input example sketch in the Serial Wombat Arduino Library. It shows how to use a Serial Wombat 4B chip to read analog inputs, including using on-chip averaging. It shows how to measure the system source voltage and how to make measurements in millivolts rather than A/D counts. A discussion is included about how resolution, reference voltage and numeric representation of measurements impact results.

The Arduino API for this pin mode is available here (the API is congruent in other language libraries):
