DSP56807 FileIO Data

Started by li_xinming October 12, 2002
Hi, all:

I `m using DSP56F807EVM FILEIO to save ADC data into a data file on
hostPC. Next, I have to process these data by MatLab Wavelet Toolbox.
The problem is I cannot load data into MatLab. Does anyone have
experience to handle the problem? Thanks for help in advance.

The following FAQ (DSP-14254) from our website may help you, in particular try the exercises that it talks about:

 

Problem:

How is Matlab supported by 56800 development tools?

 

Solution:

Matlab is not directly supported by our development tools, but you can use Matlab to generate inputs, which are readable by the EVM using SDK's File I/O. The results of processing these inputs can be uploaded from the EVM back to your PC using File I/O. Matlab can then process the outputs and compare them with predicted results.

For more details on SDK's File I/O see Section 6.2 in the SDK Targeting manual belonging to your EVM.

Examples of using File I/O and Matlab are available for 56F805, 56F807, and 56F826 EVMs. Download the 56800 FIR Lab SEA.exe (http://e-www.motorola.com/support/technial/faq/DSP/faq14254/FAQ_14254_FIR_Lab_SEA_V1.exe )or 56800 IIR Lab SEA.exe (http://e-www.motorola.com/support/technial/faq/DSP/faq14254/FAQ_14254_IIR_Lab_SEA_V1.exe ) and install it at the root of your Drive D:, then set the default directory in Matlab to D:\FIR_Lab\Matlab or D:\IIR_Lab\Matlab. In this directory you will find the Matlab script FilterLabScript.m which you can run from Matlab. Follow the prompts in Matlab.
