6. BLDC kit software

The firmware provided with this kit allows trapezoidal control of Brushless DC (BLDC) motors
using Hall-effect sensors specifically using the
32u4
nomenclature.
The firmware code is set up to be used with the Arduino IDE
Visual Studio Code
hardware and software tools, go to Arduino's
The latest version of the firmware for trapezoidal control of BLDC motors using Hall-effect sensors
(NEVC-MCTRL-100-t01), is pre-uploaded to the Leonardo R3 development board provided with the
kit. Firmware version NEVC-MCTRL-100-t01-1.0.0 comes with the following features:

For a complete description of the firmware code refer to the extensive code documentation which is
provided with the firmware code.
When running the code (with the motor provided in the kit) for the first time, you do not have to
modify any parameters unless other parameters are preferred. To make any changes, head to the
"To do" section of the code documentation to see the list of recommended changes.
