AM32-MultiRotor-ESC-FWAM32 is an open-source firmware designed for STM32 ARM processors to control brushless motors (BLDC) in electronic speed controllers (ESCs). It provides safe, fast, and smooth motor control with linear throttle response, suitable for multirotor drones, crawlers, and other RC vehicles when paired with a flight controller. ## Key Features - **Firmware Upgradability** — Supports updates via Betaflight passthrough, single-wire serial, or Arduino. - **Motor Protocol Support** — Compatible with Servo PWM, DSHOT (300, 600), and bi-directional DSHOT. - **Telemetry** — Implements KISS standard ESC telemetry for real-time data feedback. - **Variable PWM Frequency** — Adjustable pulse-width modulation frequency for optimized motor control. - **Sinusoidal Startup Mode** — Designed to smoothly start larger motors and reduce cogging. ## Philosophy AM32 emphasizes safety, performance, and versatility, aiming to deliver reliable and efficient motor control across diverse hardware platforms and vehicle applications.
