keyboard shortcuts

Post by mKoch » Wed Mar 14, 2018 1:14 pm

Hi,

when it's really cold outside, I need gloves. But with gloves I can't use the mouse. The idea is to use a cheap programmable USB keyboard, throw away the original keys and replace them by very big buttons, for example 5cm x 5cm, which can easily be pressed with gloves.
I need only a few keyboard shortcuts in SharpCap:
-- Start capture (and skip the configure capture menue)
-- Stop capture (this can be the same button as Start capture)
-- Toggle histogram on/off
-- Toggle Focus Assistant on/off
-- Toggle between full field of view and strong zoom-in for focusing
-- Gain + -
-- Exposure time + -

Thanks,
Michael

Hi,

a number of these shortcuts exist already, but they are usually not single keys - for example

Start Capture - Alt+S
Stop Capture - Escape
Quick Capture - Alt-Q
Histogram - Alt-T, H
Focus assistant - Alt-T, F, Enter

Not sure if your keyboard would be capable of creating this sort of sequence - if not there might be software available that can receive one key from the keyboard (ie F1) and in response send a sequence to the application.

I like the idea of exposure/gain up/down keys - plus and minus would make sense for exposure, not sure about a gain equivalent yet.

cheers,

Robin

Hi,

this USB keyboard can generate multiple character sequences:

Start Capture - Alt+S ok
Stop Capture - Escape not working!
Quick Capture - Alt-Q ok
Histogram - Alt-T, H not working!
Focus assistant - Alt-T, F, Enter not working!

I'm testing with version 3.0.4076.0

Hi,

the easiest solution would be to use a cheap numeric USB keyboard like this:
https://www.aliexpress.com/item/FANTECH ... 20692.html

Remove the original keys, use only the electronics, solder the electronics to big illuminated pushbuttons like this:
https://www.aliexpress.com/item/1PCS-LE ... 21264.html

But these cheap keyboards are not programmable. Would it be possible that you assign the most important functions to those keys that are on the numeric block?

Exposure time + -
Gain * /
Quick capture and Stop capture: Enter
Toggle histogram 1
Toggle Focus assistant 2
Toggle between full field and strong zoom: 3

Hi,

not sure what keys will make sense in detail yet (numeric key pad keys are not so logical for laptop users who don't have a key pad...).

However, you can remap your keys to whatever SharpCap uses with this software - https://autohotkey.com/

cheers,

Robin

Hi,

from my point of view it doesn't care which buttons you use. I can assign all sequences to the programmable cherry keyboard.
But only two of the shortcuts that you mentioned are actually working, Alt-Q and Alt-S.
Escape, Alt-T H and Alt-T F were not working when I tested them.

Hi,

you need to test 3.1, not 3.0 - I fixed a number of cases where the keyboard event wasn't getting to the right part of the code for 3.1

cheers,

Robin

ok, with 3.1 it's all working. Please include in the next version also keyboard shortcuts for gain + - and exposure + - and for changing the zoom factor

Thanks,
Michael

Robin,

do you have an example of an autohotkey script for SharpCap? If I want a hotkey that's only active in SharpCap, what I must write right of #IfWinActive ?

Thanks,
Michael
