no connection from parport.0.pin-10 to the halpin was created by sebastian1933
I cann´t display a 5V signal from the parport.0.pin-10-in on the HAL-Scope in Axis.
The .hal -file contains:
net din-00 <=parport.0.pin-10-in.
On HalScope the ch.1 ist the configuret as parport.0.pin-10-in, ch.2 as din-00 and for testing HalScope I switched the ch3 to xdir.
I can see the changes from xdir on ch.3 but on ch1 and 2 I see nothing.
The pin 10 on the Parport has a LED for checking the signal after the button.
What can I check?
Please help
great Thanks Sebastian.

The easiest way to check a HAL pin is with the Show HAL Configuration from the Machine menu in Axis. Select the Watch tab and add the pins you want to monitor.

If your wanting to see some real time pulse then HalScope is the one to use but a bit more difficult to understand and set up.

Do you have the parallel port read function attached to a running realtime thread? ie:
addf parport.0.read base-thread
