Analog-to-Digital Converter (ADC)

The EM2001 features a four-channel analog-to-digital converter (ADC). The ADC's hardware resolution is 12 bits, while its effective resolution is about 7 bits. This reduction in resolution is caused by the internal noise of the EM2001. Even with this low resolution, the ADC module is useful for a wide variety of measurements.

The input voltage range of ADC inputs is from 0 to VCC (3.3V nominal). The ADC will measure 0 when an ADC's input is at 0V and 4,095 when an input is at VCC.

Your Tibbo BASIC/C application can access the ADC module through the adc. object.
