Asked

Can you please write the code in Blockly for me for a stepper motor Movement Panel using V21 and V22? I will be inserting it into Auto Position movement panel.

To create a Blockly script for controlling a stepper motor using the Custom Movement Panel v2 with digital ports V21 and V22, you'll need to define the movement actions (forward, left, right, stop, reverse, etc.) and associate them with the corresponding stepper motor control commands.
Here's a basic example of how you might set up the Blockly script for the forward and stop actions. You will need to adjust the script based on how your stepper motor driver interprets commands and how you want the motor to behave for each action.
Here's an example of what the Blockly script might look like:
This Blockly script is a simple example that sets the digital ports V21 and V22 to specific states to control the stepper motor. The
sleep(1000)
block is used to create a delay, simulating the motor running for a certain period before stopping. You will need to replace theDigital.Set()
commands with the actual commands required by your stepper motor driver.Please note that this is a basic example, and you will need to customize the script based on your specific stepper motor, driver, and how you've wired the motor to the EZ-B v4. Additionally, you may need to add more blocks for other directions and actions as required by your project.

@Athena Can you please write the code in JavaScript for ARC for me for a stepper motor Movement Panel using V21 and V22? Break the code down into what I will have to insert in each different category Forward, Reverse, Left, Right, Stop, Pause.
Certainly! Below is an example of JavaScript code for ARC that you can use to control a stepper motor using digital ports V21 and V22. This code is broken down into sections that correspond to the different movement actions of the Custom Movement Panel v2.
Forward:
Reverse:
Left:
Right:
Stop:
Pause:
Please note that the actual commands to control your stepper motor will depend on the specific stepper motor driver you are using. The above code assumes a simple driver where setting one pin high and the other low causes movement in one direction, and reversing those pin states causes movement in the opposite direction. If your driver requires a different control scheme, you will need to adjust the code accordingly.
To insert this code into the Auto Position Movement Panel, you will need to use the
ControlCommand()
function to call the respective JavaScript functions from the Custom Movement Panel v2. Each function should be associated with the corresponding action in the Auto Position Movement Panel's configuration.I am a customer support GPT-powered AI and still learning.

@Athena pertaining to your last answer from this page I think you may be incorrect because you are only turning on a switch which is not taking into account the variable speed associated with the potentiometer of a joystick, or is that already being handled by the acceleration and deceleration which was programed in the Arduino code. Can you please write javascript code that will take care of the variable speed of the stepper motors.
To handle variable speed control of stepper motors using JavaScript in ARC, you'll need to adjust the speed based on input from a potentiometer or another control method. Since you mentioned using a joystick, I'll assume you have a joystick control that sets a global speed variable based on the joystick's position.
In ARC, you can use the global speed variable to determine the pulse rate for the stepper motor. The pulse rate will control how fast the stepper motor steps. A higher pulse rate means faster movement, and a lower pulse rate means slower movement.
Here's an example of how you might write JavaScript code to control the stepper motor speed using digital ports V21 and V22, taking into account a global speed variable:
In this example, the
pulseStepper
function takes three parameters: the direction pin, the pulse pin, and the speed. The speed variable is used to determine the pulse rate. Theforward
andreverse
functions retrieve the global speed variable and callpulseStepper
with the appropriate direction.Please note that the
sleep
function is used to create a delay between pulses. You may need to adjust the delay based on your stepper motor's requirements. The actual implementation will depend on how your joystick control sets the global speed variable and how your stepper motor driver interprets the pulses.Remember to replace the placeholder
getVar("$Speed")
with the actual global variable that your joystick control sets. If your joystick control does not set a global variable, you will need to create a mechanism to read the joystick's position and set the speed accordingly.I am a customer support GPT-powered AI and still learning.

@Athena can you follow up last answer with the Javascript code for ARC for the left, right and pause of V21 and V22 (virtual ports V21 and V22).
Certainly! Below is the JavaScript code for ARC to control the left, right, and pause actions for a stepper motor using virtual ports V21 and V22. This code assumes that you have a mechanism to set a global speed variable based on the joystick's position or another input method.
In this example, the
pulseStepper
function is used for both left and right movements. The direction of the movement is determined by the sign of the speed variable. For left movement, the speed is negative, and for right movement, the speed is positive.The
pause
function is designed to stop the stepper motor. If your stepper motor driver supports a specific pause command, you should replace the content of thepause
function with that command.Please ensure that the global variables
$Speed
and$Steps
are correctly set by your input mechanism (e.g., joystick control). The$Steps
variable represents the number of steps the motor should move for a single left or right command. If you don't have a variable for steps, you can define a constant value within theleft
andright
functions.Remember to adjust the sleep duration and the number of steps according to your stepper motor's specifications and the responsiveness you require.

@Athena Thankyou this information should take care of it.
