question about BF535 EZ-Kits example.

In BF535 EZ-Kits example: c_fir, there is Matlab file: fir_data.m. But
I can not run the fir_data.m in Matlab due to the following missiing
function:

save_fr16_init(float_to_fr16(in'), 'in.dat');

Can anyone tell me where I couild find it?

Hi,

I guess you couldn't find niether float_to_fr16(), nor save_fr16_init().

If you understand the dataformats you can write your own functions. What the
float_to_fr16() does (or at least I'd expect to do) is to convert from the
floating point format of MATLAB to the Blackfin frac16 format (Q1.15
notation). What the save_fr16_init() function does is to save frac16 data in
a file, but in hexadecimal notation. Did you open the coef.dat file?

Regards,
