Hi, I just bought a Genius USB Numpad so I can use it as an extra set of trigger keys for different applications.
Keyboard 1 has id: 2B852B30
and Keyboard 2 has id: 2866AC2B

I assigned Keyboard 1 to be called "Streamdeck"

My issue is that when using "0" on the USB numpad extra keyboard (Streamdeck), I get the registered call and ALSO the Numpad Zero on Keyboard 2.
So I get this sequence:

Code: Select all

streamdeck  :  \\?\HID#VID_0C45&PID_7663&MI_00#8&2B852B30&0&0000#{884B96C3-56EF-11D1-BC8C-00A0C91405DD} [388695651] :  keyboard
<unassigned>  :  \\?\HID#VID_04D9&PID_1503&MI_00#8&2866AC2B&0&0000#{884B96C3-56EF-11D1-BC8C-00A0C91405DD} [65609] :  keyboard
Total number of devices: 2
streamdeck  :  \\?\HID#VID_0C45&PID_7663&MI_00#8&2B852B30&0&0000#{884B96C3-56EF-11D1-BC8C-00A0C91405DD} [388695651] :  keyboard
<unassigned>  :  \\?\HID#VID_04D9&PID_1503&MI_00#8&2866AC2B&0&0000#{884B96C3-56EF-11D1-BC8C-00A0C91405DD} [65609] :  keyboard
Total number of devices: 2
\\?\HID#VID_0C45&PID_7663&MI_00#8&2B852B30&0&0000#{884B96C3-56EF-11D1-BC8C-00A0C91405DD}
Callback for device: button 96, direction 1, flags 18619437
Callback for device: button 96, direction 0, flags 18619593
Callback for device: button 96, direction 1, flags 18620515
Callback for device: button 96, direction 0, flags 18620656

My question is: How can I only make the extra USB Numpad (keyboard 1) register the keypress and not my original typing Keyboard(2)?

This is the code I am using:

Code: Select all

lmc_device_set_name('streamdeck','2B852B30')
lmc_print_devices()

print(lmc_device_set_name('streamdeck', '2B852B30'))

log_handler = function(button, direction, flags)
  print('Callback for device: button ' .. button .. ', direction '..direction..', flags '..flags)
end

lmc_set_handler('streamdeck', log_handler)

lmc_set_handler('streamdeck', function(button,direction)
  if (direction == 1) then return end
  if (button == 13) then
    lmc_send_keys('^{ENTER}', 50)

    elseif (button == 97) then
    lmc_send_keys('^{NUM1}', 50)

    elseif (button == 98) then
    lmc_send_keys('^{NUM2}', 50)

    elseif (button == 99) then
    lmc_send_keys('^{NUM3}', 50)

    elseif (button == 100) then
    lmc_send_keys('^{NUM4}', 50)

    elseif (button == 101) then
    lmc_send_keys('^{NUM5}', 50)

    elseif (button == 102) then
    lmc_send_keys('^{NUM6}', 50)

    elseif (button == 103) then
    lmc_send_keys('^{NUM7}', 50)

    elseif (button == 104) then
    lmc_send_keys('^{NUM8}', 50)

    elseif (button == 105) then
    lmc_send_keys('^{NUM9}', 50)

    elseif (button == 111) then
    lmc_send_keys('^{NUMDIVIDE}', 50)

    elseif (button == 106) then
    lmc_send_keys('^{NUMMULTIPLY}', 50)

    elseif (button == 109) then
    lmc_send_keys('^{NUMMINUS}', 50)

    elseif (button == 107) then
    lmc_send_keys('^{NUMPLUS}', 50)

    elseif (button == 8) then
    lmc_send_keys('^{BACKSPACE}', 50)

    elseif (button == 110) then
    lmc_send_keys('^{NUMDECIMAL}', 50)

    elseif (button == 96) then
    lmc_send_keys('{left}', 50)
  end
end
)

BTW My USB Numpad features the 000 button which types the three zeroes in a sequence. How can I make the above script so that only writes it one time?
I've also read you can program a second layer of functions when you "turn off" num lock. I was trying to create a script using HID Macros and also to identify they keypress code.

Please help me out.
Thanks.

Don't call lmc_device_set_name twice in your script. Try to remove the first call and keep the one in print.
Regarding 000 - probably could be with some scripting (including time measurement and ignoring quickly followed presses) but not sure if you can recognize "regular 0" and first of 000

Thank you for your reply Admin.
I will remove the first call lmc_device_set_name as you mentioned.

I am figuring some people use "mirroring commands" from the first keyboard to new keystrokes on secondary NumPad keyboard,
while others create "totally new keystroke calls (F13-F24)" on the secondary.

Is there a way to assign F13 to F24 function keys to the Numpad?
Thanks!

AFAIK you can send F13-F24 from the macro but you need some software which can receive it and do the action (like AutoHotKey or directly the program you want to control).

Cool.
Let's talk about "capturing the keystroke" before it's sent to Windows regular functions, because I feel this is where my problem currently is.
I use Blender which is a 3d software. I can configure the F13 keypress on windows for Blender to pick up the keystroke using PowerToys Keyboard
key assign (PowerToys is a native windows install application).

But here's the problem:
When I press Numpad 1 on my extra USB numpad keyboard (not my typing normal keyboard), the command gets picked up by Blender
and it also presses the regular "Numpad 1" command. So I get 2 actions with one keypress. This is not optimal.

For the past 4 weeks I've been reading about Key-press, Key-hold, Key-release. I feel I am having the case where I press the Numpad 1 (and correct
command shortcut fires off in Blender) but when I RELEASE the key, then regular Numpad 1 is sent.

How could I TRAP the keystroke so that it only sends F13 (and not Numpad 1 afterwards?)
Could you help me out with the additional code in the previous example?
Thanks! Any pointers will help!

Blocking the original keypress is basically a hack, some applications still can recognize it. Maybe Blender is one of these apps.
