library Motor Driver for ESP32, arduino and other. It has a smooth start and stop. Without interruptions.
Library for VNH3SP30, VNH2SP30, VNH3ASP30, VNH5019A-E and other driver. The library supports a smooth change in speed. Does not use interruption. If you are using ESP32/8266 remember to negotiate levels with the driver. There are drivers that support 3.3 V, there are only 5 V. This library can also work with a homemade driver.
To install this library use the Arduino library manager or use the Clone or download > Download ZIP button on the repository home page and then install the library in your Arduino environment using Sketch > Include Library > Add .ZIP Library...
Note the EN pin state. HIGH or LOW.
