ADS5560 + TSW1200 Matlab interface

Other Parts Discussed in Thread: ADS5560, ADS6149

Hello,

Is there a Matlab interface for the TSW1200 and ADS5560? Does this interface give me more options and control over the ADC then with the TSW1200 interface? I have also noticed that the TSW1200 interface loses connection with the TSW1200 board (UART speed is set at 460800).

    Hi,

    There is not yet a Matlab interface for the ADS5560 and TSW1200 combination, but it would be relatively easy to add.  The ADS5560 interface looks a *lot* like an ADS6149 interface but with another LVDS pair for another 2 bits of precision - and ADS6149 *is* supported by the Matlab interface for the TSW1200.

    But the Matlab interface would not give you any more options or control over the ADC than the TSW1200 GUI does.  There are two main reasons that I am aware of for using the Matlab interface.  One is that the Matlab would let you get simultaneous capture from multiple channels that the TSW1200 hardware supports but the TSW1200 GUI does not.  But the ADS5560 is a single channel device so this would not be a reason to use the Matalb.  Another is that some customers want to do their own processing of the captured data instead of just using the TSW1200 GUI.  But the Matlab code is *not* a GUI, and harder to use.  For example, the Matlab code does not automatically find the com port number of the TSW1200 USB connection virtual com port, and so the Matlab code has to be edited each time the com port changes.

    If the TSW1200 is power cycled or the 'Program' button is pressed, the GUI will lose its connection with the hardware.  I haven't noticed this to be a frequent occurrence otherwise.  If the USB connection is dropped due to the TSW1200 hardware being reset this way, usually just reinitializing the GUI a couple of times will restore the connection.  There is a hot-key assignment to reinitialize the GUI: cntrl-shift-i is assigned to the menu item reinitialize-instrument.  For some reason it usually takes two applications of reinitialize instrument.
