# ESC configuration

There are four on-board ESCs on the DroneCore.Power board, which can be configured through host PC(Linux / Windows) application called AMC\_manager. AMC\_manager can connect to ESC, configure parameters, identify motor, read error messages, update firmware and more.

For the purpose of switching between individual ESCs, there is a configuration application, which is executed directly on the Jetson. The ESC configuration app is a part of the provided system image.

{% hint style="info" %}
All ESC settings, configuration and motor parameters are stored in an embedded, non-removable EEPROM on the .Power board.
{% endhint %}

#### Connection and configuration flow

* The use of the complete DroneCore.Suite with Nvidia Jetson assembled is assumed.
* Connect the USB cable from the host PC (USB Type A) to the USB adapter Alink (USB Micro B)
* Connect the 3pin JST cable from the USB adapter Alink to the connector on the DroneCore.Power board marked as CONFIG.
* Start the [AMC\_manager](https://test-airvolute.gitbook.io/test-airvolute-docs/autopilots/getting-started/motor-connection/esc-configuration-app-amc-manager-v1.1.0) application and open the corresponding COM port (according to the manual below)
* Power on the board (use of a battery or a strong power supply as a power source is recommended)
* [Connect to Nvidia Jetson](https://test-airvolute.gitbook.io/test-airvolute-docs/autopilots/getting-started/connection-test/jetson-connection) (USB / Wi-Fi)
* Start the esc\_configuration app
* Follow the steps in the esc\_configuration app
* After the configuration is complete, power off the board and disconnect the cable from the CONFIG connector

#### Configuration control application

* esc\_configuration is a simple console application which communicates with the .Power board through the I2C peripheral.
* Location of the app: `home/dcs_user/useful_scripts_apps/`
* If not running on the provided Jetson image, download the executable from [storage](https://github.com/airvolute/DroneCore.Suite/tree/main/DroneCore.Suite/DroneCore.Power/Applications/ESC_configuration_app)
  * Execute sudo chmod 777 on the downloaded executable to be able to run properly
* Run the app with `./esc_configuration`
