Create the build folder: **$PICO/uSDR-pico/build**
Before doing any building you need to adapt the file **$PICO/uSDR-pico/CMakeLists.txt**, using your favourite browser, to reflect your own directory structure.
In **$PICO/** you will find a command to start a Developer Command Prompt window. Within this DCP all environment settings are initialized to enable building.

Now you have initialized the make environment, and by executing **nmake** in that same build folder, the Pi Pico loadable file **uSDR.uf2** is created.
Rebooting the Pico while the bootsel button is pressed will open a file explorer window with the Pico as a Mass Storage Device. Moving the binary to the Pico is as easy as dragging and dropping this uf2 file into that MSD.

For calculating filters I have used the free software from Iowa Hills (http://www.iowahills.com/8DownloadPage.html)
I also used the online FIR filter calculator T-Filter (http://t-filter.engineerjs.com/)
