Commands

result_t dataReady (uint16_t data) Indicates a sample has been recorded by the ADC as the result of a getData() command.

result_t getData(void)

Initiates an ADC conversion on a given port.

Returns:

SUCCESS if the ADC is free and available to accept the request

result_t getContinuousData(void)

Initiates a series of ADC conversions. Each return from dataReady() initiates the next conversion.

Returns:

SUCCESS if the ADC is free and available to accept the request

result_t dataReady(uint16_t data)

Indicates a sample has been recorded by the ADC as the result of a getData() command.

Parameters:	data - a 2 byte unsigned data value sampled by the ADC.
Returns:	SUCCESS if ready for the next conversion in continuous mode. if not in continuous mode, the return code is ignored.
