Does Altair Embed suitable for programing robot?

Phan Truong

Hi Community, I have a project relate about robot arm. In Arduino code, i have a matrix, with rows to represent state of robot, columns to represent angle of joints. This is 2D matrix. I can controller my stepper motor easily and sweep state of robot with for loop. But in Embed, I find it very complicated. I don't know how to control the motors in turn when i give it step.

Can someone help with a solution ??

Hello Phan,

 

I am sure we can help you run those stepper motors very easily. It should not be complicated at all. 

Can you please share some more details as to what motor are you using and how are you expecting it to run. What are the signals you provide for control?

If possible please attach any .vsm file here that you may have been working on and we will help you solve your problems.

 

Regards,

Mayank

Thanks for your reply.

First, I want control position of stepper motor using Embed. In arduino code. I have a for loop, with each loop is a pulse. For instance:

for (int k = 0; k < b; k++){
	digitalWrite(stepPin[j],HIGH);
	delayMicroseconds(500);
	digitalWrite(stepPin[j],LOW);
	delayMicroseconds(500);
	}

 

 

But in Embed, i don't know how to create a for loop to do this. I intend create square wave and count it to control motor. Does it feasible?

1. Make sure to select 'Arduino' from supported target while installing Embed.

2. Find 'Arduino Config' block under Embedded>>Arduino>>Arduino Config... 

3. Find 'Digital Output' block under Embedded>>Arduino>Digital I/O>>Digital Output. Right click on the block to select your I/O pin.

4. Create a diagram using 'square wave' block. Right click on it to change the pulse time.

5. Go to Tools>>Code Gen. Select your Target as Arduino. Click on 'Compile...' and then click on 'Download...'

This should get you started with a simple example.

PS - You can change start and end time in System>System Properties... 

Try different examples for PWM, Blinking LED etc under Examples>>Embedded>>Arduino>>

Yep. I know that but i have 2 stepper motor and each motor have different step. How can i solve that problem?

Hello Phan,

Are you using an external library to control the stepper motor.

If so, please refer our External library import example and make use of "Extern" blocks under Arduino.

Examples located in Examples->Embedded->Arduino->External Library Import->

Or Can you please share your code, we can create a .vsm diagram for you.

Will share you a simple stepper motor control diagram shortly.

Hi Sreejith,

 

Thank you for your response. Here is my arduino code:
