Updating numeric Control with different values with array function

[Sshenoy]

Hi ,

I have attached my basic code . I want to run the code for 2 sets of numeric control values with a delay in between and loop it. Something like this

abc

Initialize P1=10; P2=20;P3=30;P4=40

Run the code

delay = 10ms

Update P1=150; P2=200;P3=350;P4=500

Run the code

jump to abc

I am stuck how to update the values of P1,P2,P3,P4 ? I thought of using a array function but couldn't go further .

Thanks for the help,

Ana

Hello Ana,

One way you could achieve what you are looking for is by using property nodes. These Property nodes will allow you to change control values from the block diagram. You could set up a case structure inside of your while loop that will change the control value via property nodes after a certain number of iterations. Here is a community example that shows how to use property nodes to change boolean controls:

Hi Erik,

Thanks for your reply. I am trying to use the property node -> value. I am still not sure how to write values to it. Would you be having some simple example for me ?

Thanks,

Hi,

I am not sure what is the best method to update numeric control P1, P2 , P3, P4 multiple times? I have used property nodes when I had only few values to send. How can I send 4*50 array.  

I am using Dynamixel MX 64 servos in my project. I have 4 of them tied in series. P1,P2,P3, P4 represents degree rotation of each servo/axis. Trying to pass multiple set of values to these variables. 

Really appreciate your help!

Thanks,

Sahana

Hi Sahana,

Instead of using Property Nodes here, you may want to simply index the array of values with a for loop. Here is a Community Example that explains this functionality a bit further:
