## README

# AM32-MultiRotor-ESC-firmware
Firmware for STM32F051 based speed controllers for use with multirotors

</p>

The AM32 firmware is designed for STM32 ARM processors to control a brushless motor (BLDC).
The firmware is intended to be safe and fast with smooth fast startups and linear throttle. It is meant for use with multirotor aircraft and a flight controller. The firmware can also be built with support for crawlers.

## Features

AM32 has the following features:

- Firmware upgradable via betaflight passthrough - only support G4, F4 and F7 FCs, and make sure your betaflight firmware is up to date when you try to use passthrough
- Servo PWM, Dshot(300, 600) motor protocol support
- Bi-directional Dshot
- KISS standard ESC telemetry
- Variable PWM frequency
- Sinusoidal startup mode, which is designed to get larger motors up to speed

## Firmware Release & Configuration Tool

The latest release of the firmware can be found [here](https://github.com/AlkaMotors/AM32-MultiRotor-ESC-firmware/releases/).

To configure AM32 and upload firmware you can use the Multi_ESC config tool using Betaflight passthrough. They can be downloaded from here:

[WINDOWS](https://drive.google.com/file/d/1qw2f7nM6OZftIE5GTgMPWB5zXCELxYG9/view?usp=sharing),
[LINUX](https://drive.google.com/file/d/1QtSKwp3RT6sncPADsPkmdasGqNIk68HH/view?usp=sharing)

Alternately you can use the [Online-ESC Configurator](https://esc-configurator.com/) to flash or change settings with any web browser that supports web serial.



## Hardware
Target compatibility List can be found [here](https://github.com/AlkaMotors/AM32-MultiRotor-ESC-firmware/wiki/List-of-Supported-Hardware) (APR 2021)


## Installation & Bootloader

To use AM32 firmware on a blank ESC, a bootloader must first be installed using an ST-LINK. Choose the bootloader that matches the signal input pin of the ESC.
The compatibility chart has the bootloader pinouts listed.
Current bootloaders can be found [here](https://github.com/AlkaMotors/AM32_Bootloader_F051/releases).

After the bootloader has been installed the main firmware from can be installed either with the configuration tools and a Betaflight flight controller or a direct connection with a usb serial adapter modified for one wire.

To update an existing AM32 bootloader an update tool can be found [here](https://github.com/AlkaMotors/F051_Bootloader_Updater/releases).

## Support and Developers Channel

Etiquette: Don't ask to ask and please wait around long enough for a reply - sometimes people are out flying, asleep or at work and can't answer immediately.
