DSP Robotics Support

Hello,

I am trying to get x,y coordinates from a module when the mouse moves and separately when the mouse clicks.
Using the LDO module i can get mouse clicks but when i try to recreate that in ruby code it doesn't output anything.

Also i have the ruby code for following the mouse position and it updates from the second level over the bit map module but not when i go to the top level?

The module i am trying to do this on is the bit map module. I have attached my code.

Can anyone see anything wrong with it? Im not sure if the code is wrong or i have missed a step/setting?

Thanks for the help

Rob

Hi there, Visteon, welcome to the forum.

You'll be glad to hear that it won't take much to get your schematic fixed - looks like a very interesting design, I'm from more of a Audio DSP background myself, so I find what you robotics and control guys are doing fascinating.
Anyhow, one at a time...

1) Mouse Over
This is just a matter of GUI "levels". When you have several modules nested inside each other, the "MouseOver" input on the MGUI primitive has to be turned on for all of the levels above the one where you need to pick up the signal. In this case, you just need to add a boolean true to the MGUI in the main "mother" module.

2) Mouse Click
Two things you need to do...
a - Disconnect the 'mouse down' primitive. Mouse messages can only ever get picked up by one receiver at a time, so you have to choose between Ruby or the primitives.
b - The mouse clicks will send a message with your code - but it's being sent to the same 'shared' output as the mouse over movements. To send the data separately, create new outputs by dragging the little widget downwards, and right click the outputs to select an appropriate type of data (float in this case). Then you need to tell Ruby to use the new outputs by adding an index number to the output code - sometihing like this...

(NB - the first output is at index zero - the one being used by the mouse over readout).

Hi trogluddite,

Thanks for the reply.
I have changed what you have said and now it works, thanks.
But the mouse movement gives me the coordinates across the entire top level GUI not just the Module i have written the code in, how can i limit this to just the module?

Thanks
Rob
