Hi!
Thank you for reference.
I write this hal function.
It's OK. BUT!!!
I need to execute only ONE instruction (string in G-code programm).
After the executing instruction, the EMC has to be in paused state and wait foe the next button press.
How can I do it?

Look at the halui.program pins... and you will have to do a bit of logic to make sure that EMC is in a state that the pin will work. Also keep in the back of your head that single step means execute up to the next line that causes movement.
