Implementing FIR lowpass filter using code composer studio on C55X family

Thread starter #1
Hi guys,

i'm pretty new to dsp, i would like to implement FIR lowpass filter to a recorded audio clip using codecomposer studio on c5545 booster pack. Can someone provide me a step by step guide to build the project? I've C code for it.

I'm giving analog input through line in, is there a function or c code to obtain the input data samples to use it in my fir function? I would like to run the code on ccs and hear the output from headphone output.

Thanks in advance

Hi can someone shed light on this? Thanks
I've never gone past that point. I probably know about the math part just as much as you: just punch samples into the equation and get the output. I can't help on on what, to me, would be the hardest part which is getting the samples in...that's probably just playing it back somehow and sampling it with an ADC.

ok, i implemented an example project from c5545 boosterpack software folder to build using code composer studio, with following attached build errors.
