Use Arduino as Keyboard

[komurcu]

Hi guys. i wrote some codes for arduino uno.

I want to simulate switch for DCS.

it is sending key to pc.

for example

.....

buf[2] = 7; // D keycode >> PITCH ATT HOLD

Serial.write(buf, 8); // Send keypress

releaseKey();

delay(vrKeyDelay);

.....

if i set it for Roll - HDG Sel switch, it is working,

but if i set it Pitch - Alt Hold switch it is not moving (if switch position on ALT HOLD or ATT HOLD, it is moving A/P Off state) . when i press 'D' key on keyboard switch is moving.

I test it on BMS it is working on Pitch or Roll switch

 

i will use DCS-Bios but that way easyest to send command to DCS

Unfortunatelly DCS-Bios needs a lot of ports on Arduinio. I am trying decrease count of them

 

Can you help me

Is that a momentary switch your using there? Does it need to keep the keypress down, rather than release? So the release would only send when it goes back into the center position.

 

I can't remember how that switch works, I'll have to open it up and have a play.

yes i recognized it.

but if i use real keybord and press (and release) 'G' it is working correctly.

i could not understand why.

As far as I'm aware, only a couple of the more obscure Arduinos are capable of working properly as a keyboard.  The usual ones, like Mega, Uno, Nano, etc. have the wrong kind of USB port setup in them.
As for ports, DCS-BIOS uses no more than a keyboard interface would.

You're probably talking about the Arduino Leonardo which has the ATmega32U4. This allows it to be plugged directly into a PC and recognised as a USB device.

 

I use the Leonardo exclusively for DCS, and have them show up as joysticks. Each joystick has a number of axises which can be used for potentiometers and around 32 buttons for switches/buttons/rotary encoders. Using this setup I can make each of the functions to whatever is needed in DCS.

 

I also have one Leonardo setup to send keyboard commands which come from a few 3x4 keypads.

I haven't done anything with DCS Bios, but if you're sending the command via serial then it looks like this might work:

Serial.println("AP_PITCH_SW 2");

 

Otherwise you might be able to use their own commands with :

 

sendDcsBiosMessage("AP_PITCH_SW", "2");

 

I found the F-16 command list here:

thanks i will check. is there any documantary which i can read for more data. because of some jsons are empty
