Servo Controller Mod component

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

Component Source Code

Detailed description

No detailed description exists yet for this component

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.






Macro reference

AutoMoveToPosition

AutoMoveToPosition
Automatically moves towards the new position with a fixed rate of 100 steps per second. 
- BYTE Channel
The channel to set the position for. First channel is zero. 
- BYTE Position
Position to move to. 
- VOID Return


DisableServo

DisableServo
Disables a servo channel effectivly disabling the motor. 
- BYTE Channel
The channel to set the position for. First channel is zero. 
- VOID Return


EnableServo

EnableServo
Enables a servo channel effectivly setting the position of the motor to the value in the local position variable. 
- BYTE Channel
The channel to set the position for. First channel is zero. 
- VOID Return


Initialise

Initialise
Sets up the servo motor interrupts 
- VOID Return


IsAutoMoving

IsAutoMoving
Is the AutoMoveToPosition movement complete. Returns 1 if the servo is still moving. Returns 0 if the servo movement is complete. 
- BYTE Return


MoveToPosition

MoveToPosition
Moves a single step towards the new position, the rate of movement is determined by how often the move to macro is called. Returns 1 if the position has been reached. 
- BYTE Channel
The channel to set the position for. First channel is zero. 
- BYTE Position
Target position to move towards. 
- BYTE Return


SetAutoMoveSpeed

SetAutoMoveSpeed
Sets the speed of the auto move to position macro. Default speed is 1. 
- BYTE Speed
1=Slowest (Default), 2= Double, 3=Triple, 4=Quadruple 
- VOID Return


SetPosition

SetPosition
Moves directly to the specified position with no interpolation. 
- BYTE Channel
The channel to set the position for. First channel is zero. 
- BYTE Position
Target position to move towards. 
- VOID Return


SetTrim

SetTrim
Allows the level of trim for each servo channel to be adjusted progmatically. 
- BYTE Channel
The channel to set the position for. First channel is zero. 
- BYTE Trim
0=0us, 1=+25us, 2=+50us, 3=+75us, 4=+100us, 5=-25us, 6=-50us, 7=-75us, 8=-100us 
- VOID Return


Property reference

Properties
Channels (1 - 8)
Set the number of servo's that you need to control. Value from 1 to 8. 
Connections
Channel 0
Pin on which to output PWM for the servo motor. 
Trim
Trim 0
Trim the pulse width for this channel. Use this to trim the positioning of two servos so that similar input values will produce the same degree of movement. 
Pulse Width
Minimum (us)
Shortest pulse width that will be used. 
Maximum (us)
Longest pulse width used for the PWM signals. 
Simulation
Servo Object 0
Drag a servo motor component onto the System Panel, and then select it here, to create an on screen simulation of the way that your flowchart moves the servo's. Servo motors should be based on the 'Servo Motor Base' component, or use a custom component set to responf to 'User.Notify' events (ID = n/a, Data = Position (0-127)).
