Hi,
The output of the
NI-845x I2C Write Read.vi is an array you could connect that array to a Graph or Chart to visually see it or you could use Build Waveform to build the array into a waveform data type.
As for the
General I2C Write Example, currently it is only setup to Write but you could add the read functionality by adding a similar configuration to that of the
General I2C Read example. Some more information about the you being able to see the waveform or what you are doing would be helpful.
