Discussion about writing software for VS1005 and the VSOS Operating System. Also posts about VS1005-related hardware design and device drivers should be posted here.
I want to make an EQ driver. When I consult the VSIDE_DSP_LIB document, I see the following content, indicating that 32BIT is not supported at present. If 32BIT is supported, ir2vsdsp.m needs to be updated, right
8.1 fir2vsdsp.m
B_ROUNDED = fir2vsdsp(B, BITS, UPSAMPLEBY, DOWNSAMPLEBY,...);
Parameters:
• B - Fir filter
• BITS - Number of bits. Currently only 16 is supported.
• UPSAMPLEBY - How many times to upsample before filtering
• DOWNSAMPLEBY - How many times to downsample after filtering
