LMD18200 Arduino Library

This Arduino library provides an easy-to-use interface for controlling the Texas Instruments LMD18200 motor driver IC. The LMD18200 is a 3A, 55V H-bridge designed for driving DC and stepper motors, and it supports features such as current sensing, thermal shutdown, and configurable PWM control. This library supports both sign/magnitude control and active braking modes.

Features

• Speed and Direction Control: Set motor speed with a signed value (positive for one direction, negative for the opposite).
• Braking: Activate an active braking mode.
• Current Sensing: Read the current drawn by the motor via an external resistor.
• Thermal Monitoring: Check the thermal warning flag status.
• Easy Integration: A simple API wrapped in a C++ class.

Installation
