<<Request>> long-press operation

[koyoko1127]

I want to activate different key codes by long-press and short-press

It is an operation that is not found in a normal PC keyboard, but it is a popular operation in embedded systems. It can be used for careful operations and infrequent operations.

Thank you for the wonderful environment for me!

Although, it sends long-press keycode on UP after a long-press (not at the set time),

kbd.define_mode_key :SHORT_A_LONG_1, [ Proc.new { kbd.send_key(:KC_A) }, Proc.new { kbd.send_key(:KC_1) }, 500, nil ]

is not enough?

[koyoko1127]

Wow　It's almost working!!

In my behavior, the keycode is entered with Long-press set time (500). (Not key UP) And, If the Long press time is set to 2000, key omissions will occur in continuous operations. (short -> long -> short -> long ......) I think the cause is that the timer has not been reset.

Keyboard#define_mode_key was basically designed to combine a normal key and modifier/layer hold key. Maybe I should implement a new feature to fulfill @koyoko1127's request. Let me think how to realize that because I'm personally excited that PRK Firmware will possibly be used in prototyping a real product 💪

Now I'm thinking of a feature as "Triple function key" like this:

Behavior model example

                :KC_0
                |
     +----------+
press^          ^release (< 300ms)

                            :KC_1
                      |     |
     +----------------+-----+
press^                |     ^release (between 300ms and 2000ms)
                      |
                      |                   :KC_2(just once)
                      |                   |
                      |                   |       Nothing happens (resets timer internally)
                      |                   |       |
     +----------------+-------------------+-------+
press^                |                   |       ^release (2000ms <)
                      |                   |
     +================+===================+=================
     |                |                   |
     0ms              300ms               2000ms

Namely, three different behaviors are articulated by two threshold values.

In keymap.rb

kbd.add_layer :default, %i(BUTTON KC_ENTER KC_SPACE KC_BSPACE) # meishi keypad for example

Then,

kbd.define_triple_function_key :BUTTON, :KC_0, 300, :KC_1, 2000, :KC_2

If you don't want the "second release key" to happen:

kbd.define_triple_function_key :BUTTON, :KC_0, 300, :KC_NO, 2000, :KC_2

If you don't want the "long press key" to happen:

kbd.define_triple_function_key :BUTTON, :KC_0, 300, :KC_1, 2000, :KC_NO

Each keycode can be an Array of Symbol or a Proc for example:

kbd.define_triple_function_key :BUTTON, :KC_0, 300, [:KC_LSFT, :KC_A], 2000, Proc.new { kbd.macro "Long!" }

@koyoko1127 Tell me what do you think

[koyoko1127]

Thank you for your aggressive suggestions. If you are aiming for a multifunctional long press operation, you need to think about the context of use. I have 4 stories（See figure below） I think this includes Hi-dynamic range operations with repeat motion. Set the repeat interval time or set nil.

[hasumikin]

@koyoko1127

[a]      [A]      KC_NO      0

This is not a case this feature should cover because...

kbd.define_triple_function_key :BUTTON_A, :KC_A, 300, [:KC_LSFT, :KC_A], nil, nil
kbd.define_triple_function_key :BUTTON_B, :KC_B, 300, [:KC_LSFT, :KC_B], nil, nil
kbd.define_triple_function_key :BUTTON_C, :KC_C, 300, [:KC_LSFT, :KC_C], nil, nil
kbd.define_triple_function_key :BUTTON_D, :KC_D, 300, [:KC_LSFT, :KC_D], nil, nil
kbd.define_triple_function_key :BUTTON_E, :KC_E, 300, [:KC_LSFT, :KC_E], nil, nil
kbd.define_triple_function_key :BUTTON_F, :KC_F, 300, [:KC_LSFT, :KC_F], nil, nil
kbd.define_triple_function_key :BUTTON_G, :KC_G, 300, [:KC_LSFT, :KC_G], nil, nil
(...)

Nobody wants to write such a verbose code, right? (Of course you can do it. But it's not meant to be done)

BTW, could you tell me more about "Hi-dynamic range operations"? I don't know it.

[hasumikin]

Ah, but, you may be able to write like this, lol

("A".."Z").each do |c|
  kbd.define_triple_function_key "BUTTON_#{c}".to_sym, "KC_#{c}".to_sym, 300, [:KC_LSFT, "KC_#{c}".to_sym], nil, nil
end

Evil Ruby...

@hasumikin

I don't know what " Hi-dynamic range operations " is officially called.

For example, when searching for an arbitrary value from 0 to 1000. If you have a wide range of values ​​and want to set them in detail, you need both micro motion and coarse motion.

micro motion (微動） ==> 0,1,2,3,4,....1000 coarse motion（粗動） ==> 0.20,40,60,80,.....1000 *It is better to have a repeat in the long-press

From now on, we need to control high resolution and large (long) size data in photo, CAD, and video. Using multiple inputs with one key, I prototype an embedded product.

Thanks

@koyoko1127 Understood, thanks! Let me think for a while
