Floating Point Biquad

[WMXZ]

triggered by other thread I played around with audio biquad filtering

I wanted to use CMSIS floating point within (together with) audio library

so I came up with the attached test

It has an example ino file
and two files to be placed with the ino file

everyone interested may play with them

simply copy content of zip file into local Arduino directory and open from Arduno IDE

This attached file cannot be download. Something wrong with uploading procedure

 

[WMXZ]

just downloaded it myself and can read all files

Ops sorry something wrong with Chrome. i used Firefox then. Now it displays. I'm sorry

This things only can be use with Teensy 3.6 right?

It makes only sense with build in HW Floating point processor (T3.5,T3.6)
I compiles and runs also on T3.2 but uses SW float point instructions
