Hello Jeff,
JEFF I THINK THERE IS SUPPOSED TO BE ACTIVATION FOR THE LED TO SWTICH-ON WHILE
I CLICK ON THE BUTTON OR THE CHECKBUTTON - THIS NEVER WORKED
Thank you for your response, the BUTTON and the CHECKBUTTON now is like and OR
gate. This is ok BUT the LED does not come up, it doesn't light up. My
intention is to light the LED with the two buttons. I have try so many
simulation but it did just work. I was on it for more than 4hrs.
when went to the HAL SHOW CONFIGURATION in the WATCH, this is result:
WATCH
· pyvcp.my-button
· pyvcp.my-checkbutton
· pyvcp.my-led
the LED never came up.
I also went into the integrators manual to see an example but the example of
where
such was done has for only an old version of EMC 2.1, it doesn't have for
latest
vesions.
The example in the integrators manual that I tried to follows is in page 155
under the
sub heading;
17.7 VCP: A small example
WHAT DO I DO NEXT PLEASE GUIDE ME!

When I followed your directions, emc displayed the following error:
postgui.hal:1: Signal 'led' can not add OUT pin
'pyvcp.my-checkbutton'
This is because your 'net' command does not make sense. When emc
rejects your hal configuration, read and understand the message, because
it is the key to resolving the problem.
Here is why it does not make sense: A signal can have one "writer",
but
my-button and my-checkbutton are both "writers".
When I revised the 'net' line to read
net led pyvcp.my-led pyvcp.my-checkbutton
the state of the LED follows the state of the checkbutton.
If you want to have either of these sources affect the button, then you
have to add "something else" which controls how the two information
sources interact. Perhaps it is an 'or2' component. 'or2'
works like
a 2-input OR gate in electronics. Assuming that you do not already
otherwise use the 'or2' component, the lines for your postgui.hal file
would be something like this:
loadrt or2 count=1
addf or2.0 servo-thread
net b1 pyvcp.my-button => or2.0.in0
net b2 pyvcp.my-checkbutton => or2.0.in1
net led or2.0.out => pyvcp.my-led
