Comments
This function sets the input full scale, impedance and coup-
ling
This function configures the input
This function configures the analog trigger block for each
channel
This function configures the acquisition of words Data
Acquisition (DAQs)
This function configures the digital hardware triggers for the
selected DAQ Trigger
This function configures the analog hardware trigger for the
selected DAQ Trigger
This function reads the words acquired with the selected
DAQ Data Acquisition. It can be used only after calling the
function DAQconfig and when a callback function is not con-
figured
This function starts acquisition on the selected DAQ
This function starts acquisition on multiple DAQs
This function stops the words acquisition Data Acquisition of
a DAQ
This function stops the words acquisition Data Acquisition of
multiple DAQs
This function pauses the words acquisition Data Acquisition
of a DAQs. Acquisition can be resumed using DAQresume.
