ADC Converter

The Vinculo module is fitted with a MCP3008, 8 channel analogue to digital converter (ADC) with SPI

output.

The analogue inputs are tracked out to the header pins such that an external signal may be applied for

the VNC2-64Q to read the values with its SPI master interface.

Alternatively the VNC2-64Q PWM interface may be used to provide waveforms for the ADC to convert and

the VNC2-64Q can read the digital output over SPI in a loopback arrangement.
