I wanted to test FFT on the Raspberry Pi Pico so I could create a real-time spectrum analizer using an LED strip. I have used MicroPython and Thonny for everything up until now. But FFT is only implemented in C for performance reasons. So to get started I had to install the Raspberry Pi Pico SDK on my Mac running Montery.
The Raspbery Pi Pico SDK code is here:
https://github.com/raspberrypi/pico-sdk
I installed it but the examples did not run because brew didn't support the EABI GCC
