Default PIC32 Audio Equalizer (EQ) Filter Library

Hi

I just across this last night, Microchip has release a PIC32 DSP EQ library, at first glance the code seems a bit over bloated (they claim its been optimised ) The code has a matlab simulation, good documentation and a few demos. At the moment im busy with another DIY project so I wont be looking into this until I complete my stuff.

If anyone is interested have a look and let us know what the success is using this, would be great to start offering a decent easy to use DSP library. (which at the moment doesn't exist)

PIC32 Audio Equalizer (EQ) Filter Library

Thanks

Thanks for sharing!

I am wondering if the PIC32 is the right platform to start a new project?
There are a lot of new ARM Cortex M4 coming out - and this seems to be the platform of the future.
On the other hand the PIC32 is very price competetive and comes with a lot of RAM and interfaces (USB HS, 4x I2S) and nice LQFP64 - LQFP144 packages.

The library docu says, that you need about 50 Mips for a 8 channel EQ. The 200 MHz PIC32 can do no more than a 32 EQ...

Thx, Udo

Hi udok I just saw your message today.

Yeah the cortex M4 based cores seems like a good candidate im not sure about the I2S ports... the M7 core is scheduled for next year that would be an even better option.
