Port DAQ Code to the Modern DataAcquisition Interface

Translate legacy session-based Data Acquisition Toolbox code (daq.createSession, addAnalogInputChannel, DataAvailable listeners, startBackground, queueOutputData, wait) to the modern DataAcquisition interface introduced in R2020a (daq("ni"), addinput, ScansAvailableFcn, start, write, preload). Also covers writing new multi-feature DAQ scripts where the modern API patterns are easy to get wrong under cognitive load.

When to Use

• Porting an existing script that calls daq.createSession, addAnalogInputChannel, addAnalogOutputChannel, addCounterInputChannel, addCounterOutputChannel, or addDigitalChannel.
• Replacing DataAvailable / DataRequired / ErrorOccurred listeners with ScansAvailableFcn / ScansRequiredFcn / ErrorOccurredFcn.
• Replacing startBackground / startForeground / s.wait() lifecycle calls.
• Replacing queueOutputData with preload + write.
• Writing a new DAQ script that combines two or more of: external triggers, continuous acquisition, callback-driven streaming, analog output with refill, or cross-callback state.
• Debugging errors like Undefined function 'wait' for input arguments of type 'daq.interfaces.DataAcquisition' or Unrecognized method, property, or field 'Data' for class 'matlabshared.asyncio.buffer.ElementsAvailableInfo'.
