LDC1612EVM: Real time data streaming from EVM to Matlab

Part Number: LDC1612EVM
Other Parts Discussed in Thread: LDC1612

I'd like to be able to synchronize an actuator which I control from Matlab with the data stream received from the LDC1612/1614EVM.  Do you have a suggestion on how this could be done in real time?

As an alternative to real-time logging, I could stream the LDC data to a log file and later time-correlate it to the actuator data.  I would need an absolute time-stamp in the LDC data for that.  However, the log file generated by the EVM GUI only contains relative time-stamps for the LDC samples.

Thanks!

    Hello Matthias,
    The GUI does not currently support the timestamp feature. What I would recommend if you want to correlate your actuator data to the LDC output is to operate the actuator very slowly such that you are going by single increments and letting the LDC sample that particular position several times.
    Alternatively you can write your own firmware to communicate with the LDC. We offer the ability to break off the micro controller portion so that you can connect directly to the device I2C lines if you already have a micro controller that you are familiar with.
    Regards,
