Welcome to LinuxCNC.org

how do i set the halpin to interger value ?
in the xml file or hal ?
if in hal, pyvcp.testimage0
pyvcp.testimage1
etc ...



The "image_u32" is the same as "image_bit" except you have essentially an unlimited number of images and you "select" the image by setting the halpin to a integer value with 0 for the first image in the images list and 1 for the second image etc.

I am not completely sure what the question is, but if you want to choose different images based on a number of bit-type inputs then the "weighted_sim" component might help.
(I don't know why it is called that, a better description would be "bit2binary")

i'm trying to use u32 image

linuxcnc.org/docs/html/hal_pyvcp.html section 1.6.6.2 Image u32

Yes, I understand that you are trying to use u32Image. My question is about how you want to control it.

What is the data type of the date you want to indicate?

well, i'm trying to use a button to change the image three times.as with image_bit.
i found a u_32 pin(halui.joint.selected) and used that to get the pyvcp button to show in axis.
now i'm trying to click the button to change the images. i have the button and the
first image is displayed but never changes. but the way you asked the question makes me think
i don't understand u32


Thanks

Click the X Y Z buttons in the Axis UI and you will probably see the image change.

You need to have a u32 pin which has a value that changes as a result of your button press.
I can think of ways to make a value count up by one every time a pyvcp button is pressed, but it is likely to involve a lot of edge detectors and other functions
