A implementation of a Cascaded Integrator Comb filter for the Cortex M4, designed to have an API similar to CMSIS-DSP.
NOT CURRENTLY WORKING
- Python 2.7
- matplotlib
- numpy
- Ipython and Bokeh (for full notebook, not for basic tests)
- GNU make
- A C compiler
With python 2.7, matplotlib and numpy installed.
###To graph sin, square waves, frequency response.
$> make
$> make test
See ./test_results for some pretty graphs.
###To test a full 2 stage chained filter (requires ipython)
$> ipython notebook
Then open the notebook and run each cell in turn.
###Cleanup
$> make clean
- cic_decimate_q16 is probably broken, do not use.
- The full two stage filter is only in the ipython notebook.
