How to know the handle of an opened HID ?

[RASMIB]

Hi Pete,

I am using Linda which opens auomatically all USB connected HID devices.

How can I found the handle returned by the function com.openhid(VID, PID, unit, repno) ?

Not sure what you mean. As you say, the handle is returned, so your Lua program has it.  It is merely a pointer into an internal FSUIPC or WideClient structure. It has no use outside of the context in which it applies. What are you wanting it for?

Hi Pete

I am using Linda

Linda is a nice tool as long as buttons are concerned

The problem is the displays of my Saitek Pro Flight Radio and Multi Panel

How can I command these displays ?

with your function com.write(handle, "string") of course

My concern : how can I found the handles of the HIDs open by LINDA

The HID must be opened because the buttons are reacting

I really appreciate your help

Does LINDA use the comhid functions or simply the normal joystick button detection?

 

In any case the handle is local to the thread which created it -- you'd either need to put you code into the Lua being run by LINDA, or get it to run call your Lua functions as an external module.

 

Easier to simply use openhid in your own Lua code. With USB devices several programs can have them open at the same time, it isn't like the old serial port system.

I don't know how Linda opens the HIDs

It's a very good new that one USB device may be opened by several programs at the same time

Thanks and have a good day Pete
