Servo Motor Controller component

Can control up to eight standard PWM driven servo's. Supports 8-bit and 16-bit movement resolutions. 'Servo Object' properties allow you to connect the controller to on-screen simulations using the "Servo Motor" component and its derivatives.

Examples

Importing from v5

The servo component in Flowcode v6 onwards has a new Initialise macro which will need to be added to your program before any other calls to the servo motor component are made.

Controlling a servo with an analogue input

This example reads the value of the analogue potentiometer and uses this to set the position of the servo motor. Servo Example 1 The Servo controller is linked to the standard servo component but this could be linked to any object on the panel.

Creating a multi-axis actuator using servo motors

This example links two servo motors together using panel primitive objects and groups. Servo Example 2 The Servo controller can handle up to 8 motors and is used to control both of the standard servo components on the panel.
