Analog-to-digital Converter (ADC)
The WM2000 features a three-channel analog-to-digital converter (ADC). The ADC's hardware resolution is 12 bits, while its effective resolution is about 7 bits due to the device's internal noise.
The ADC input voltage range is 0 ~ Vref — which is 2.5V nominal. The ADC will measure 0 when an input is at 0V and 4,095 when an input is at VCC.
Your Tibbo BASIC/C applications can access the ADC through the adc. object, which is documented in the TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual.
