Class ArduinoDAQ

Class Documentation

class ArduinoDAQ

Base class that implements communication to and from an external Serial or USB interface via According to the SCPI specification, the measurement process is broken down into several stages. First, there is configuration of the measurement done via the CONFigure command. The INITiate then physically performs the measurement, and FETCh? does any necessary postprocessing and returns the data. I will implement MEASURE, CONFigure, and FETCH, as I don’t see a purpose to implement INITiate or READ.

Public Functions

Arduino DAQ Constructor

void ProcessInput(Stream &interface, char *terminationCharacters)

Wrapper for SCPI ProcessInput function.

Parameters

  • interface: address (?) of Stream interface (i.e. Serial, SerialUSB)

  • terminationCharacters: string of expected characters at the end of every SCPI command
