Key simulators
« on: December 30, 2016, 09:02:58 AM »
I think I like tweaking/enhancing my machine and controls as well as I like making parts! (wood signs mostly)...anyway...I am going back to the drawing board on a new screen set...may buy a touch screen, but that will be the general design...will probably emulate the new Haas stuff.
I do not want a full on keyboard, but on my manual operation page, I would like a few keys (G,T,M, etc) and a number pad...what I am looking for for is guidance on how to press one of the keys and place its value in the MDI. I could brute force it by building a string in a variable and maybe script it to make whatever I am doing happen, but it would be way cooler if I could press my buttons and fill out the MDI, then press enter to execute...as I am typing this I suppose I could fake the MDI and use a user label...hmmmm...if anyone has an elegant solution or point me in the right direction I would love to hear it...

Thanks
Leslie

Trying to build a string and not working

When I press the first key (clears the msg)

msgtext="" ' clears the variable

msgtext-"G"
SetUserLabel(51, msgtext)

This works, but when I add to the string with the next keypress, it clears the string

Another key...

msgtext=msgtext & "5"  'add the 5 to the string
SetUserLabel(51, msgtext)

In my mind, msgtext should now be "G5", but after pressing both of these keys, I am only getting the 5. is "&" the proper concatenation operator?


Here is my simple keypad

Has each button got its own bit of VB code because the variables are local to that code so you need to save your string to a LABEL/DRO and read it back before you add to it and then re-save it back to the LABEL/DRO.

I'll bet that is it..."msgtext" is not a global variable! I assumed it was...so if it was local, it would behave as it is...good suggestion! I will try to write it to a dro. I can make a DRO a string correct?

Thanks

If I get this to work, at the end I have to make the MDI equal to the test string...I am at work and not able to look in any of the Mach manuals, but how would I go about actually "executing" this? As I am typing this, maybe it does not have to acutally go to the MDI, I could writer code to simply run the string....hmmmmmmm...so I could use a "fake" mdi (the userlabel that represents the string I built) and have a go button to build the code to run...

will give it a try...

Pretty simple once I got into it...may get clever and put a backspace key in at some point...this is my manual screen and my main screen
