### ⭐⭐⭐⭐⭐ Works great
*by J***E on November 7, 2020*

I followed the tutorial on the manufacturers web site and did all the examples. They all worked but when I tried the ones where blinking the LED was included they crashed. commenting out that part of the code, they ran perfectly. I am now developing my own code to build a noise reduction filter (DSP filter) for my ham radio set. The total cost of the processor board and this board is much less than one of the off the shelf DSL filters and I get to optimize my own code.
