STR912FW44 and DspLib

Hi,

I’m testing the STR912FW44 chip with GCC and STR9 DspLib. Has someone manage to compile it with GNUARM GCC?

The dsp lib has been ported to gcc in the IDEaliST from Anglia:

I looked at the page and I can't find it. Could you please be a bit more specific?

regards, Erik

Hi,

Download Anglia STRx Toolchain (4.1.1) and install it, then you'll find all the Dsplib in the install folder. Regards MBS

Thanks!

The port seems to be exactly ly the one I did. And it has the same problem. long in[1024]; long out[1024]; memset(&in, 0, sizeof(in)); memset(&out, 0, sizeof(out)); /*Generate sin wawe, Fs=800, f=80, amp=32767*/ gSin(in, 1024, 800, 80, 0, 32767); test_fft = str91x_DSP_INIT(); test_fft->calc_cr4fft_1k(out, in, 1024); When testing this, with a simple sin-wave, I don't get the expected result. I just get a lot of random data. Please help me! [ This message was edited by: erila107 on 30-05-2007 10:35 ]

Skip my last post. I've found the same bug in my code as in the port I downloaded.

Change .word to .short in the Table_FFT.
