We just published a new article, demonstrating the Speed controlling of a high-speed Brushless motor using Raspberry Pi and SOLO by coding in Python.
There we show how easily you can interface Raspberry Pi to SOLO for Closed-loop controlling of a BLDC reaching up to 30,000RPM in sensor-less mode with Field Oriented Control.
