Hi,
I'm using EventGhost with Flirc receiver. If someone doesn't know what it is then it is a keyboard emulator that can record IR codes from remotes and assign them to specific keys.
Everybody knows that keyboards cannot be supported by Generic HID plugin. But some time ago Flirc got new firmware with media keys support. Media keys are sent with different HID usage table number and are not threated by the Windows in the same way as normal keys. They don't show up in EventGhost when using Keyboard plugin as they are not intercepted by the HID keyboard filter driver. And here comes the Generic HID plugin to the rescue. It gets events from Flirc sent from table 12 where the media keys are defined as <Some prefix>.Button.<Decimal for HID button code>. Everything so far so good.
Unfortunately I have a problem with enduring events. When I press a button on remote I get multiple repeated events instead of one. I really need to very quickly release the key to get only one event. If I hold the button I get the same event repeating itself all the time. I've been checking the behavior with Enduring events turned off.
WIthout RAW events I get something like that (in <> is what I do, button number is just as example, Prefix is set to Flirc):
<Pressing button on remote>
Flirc.Button.150
Flirc.Button.150
Flirc.Button.150
Flirc.Button.150
Flirc.Button.150
<Releasing button on remote>
Flirc.Button.None
When RAW is enabled it changes to (code is a hex representation of the HID code):
<Pressing button on remote>
Flirc.0C96
Flirc.0C96
Flirc.0C96
Flirc.0C96
Flirc.0C96
<Releasing button on remote>
Flirc.0C00
Is there I can do in the EG itself to fix that? I wanted to assign all the button on remote to different codes in table 12 and map them using EG to XBMC and other applications. But with above behavior I get multiple actions on each key press and I can't use long press detection for adding more actions to some buttons.
---edit---
I've been analyzing source code of this plugin and the Keyboard plugin. I've added some prints in callbacks to see what is happening there. Now I know that Keyboard plugin doesn't really do much because it itself gets only events on key press and key release. In my situation HIDThread calls the ButtonCallback repeatedly when the remote button is pressed. I think Generic HID plugin could have a configurable option to threat repeating events within some small interval as an enduring event.
---edit---
I've copied HID plugin (changing GUID etc) and created a quick modification. I've added last_event attribute in __init__ and set it to None. Then, if enduringEvents is enabled I've added additional condition before calling TriggerEnduringEvent to check if last_event is different than evtName. If yes then last_event attribute is set to current evtName and TriggerEnduringEvent is called. Also on release event if enduringEvents is enabled I've added a line resetting last_event to None. It is a quick hack as there should be also some timeout in case the release event is lost somewhere (EG would probably think that the event is still occurring).
