Importing data from Interface TX-Matlab to excel

Post by NigmaTech » Mon Jun 02, 2008 2:18 pm

Hi Lubin!

Is that possible to import data, received using Interface TX-Matlab,
to EXCEL using some simple method?

I must to filtrate signal from IMU gyro (ADXRS150) and accelerometer. Propably I shoul implement Kalman filter, but I don't know how. Filtering is something new for me. Could you help?

To import data received using Interface Tx-Matlab, I can see two methods :
First of all, receve data in the matlab workspace using the graphical interface.
To remove NaN values from the R matrix, use the custom made function : R = padr(R,1);

Then, either you save data using a file format that Excel can understand (like cvs file format),
or just open the R array with the matlab variable viewer, and copy-past to excel.

I may write a webpage describing methods to log data using the Tx-Matlab interface. There are few tricks that allow to obtain complete data with a fine timing.

For the filters of gyro and accelerometers, you may have a look on this exemple given on the website.
If you are beginning with digital filter, You should avoid starting with adaptive kalman filter.
