DCS-BIOS: Overview and Announcements

[Vinc_Vega]

If touches can be programmed as a kind of dedicated arduino inputs, I could imagine that commands may be send to DCS-Bios.

But I haven't done so yet.

not without "help".

its an "Basic" program to communicate/interact with the Game. You need an software to "translate" it.

 

As example - DCSFlightpanels = "converter" for StreamDeck and Saitek/Logitech Flight Panels 

Or with an Arduino library you can programm arduinos for your need

Thanks.

Gun sight switch and Variometer (VVI) work well.
WRT the bomb door switch: it doesn't self-reset when it reaches the end of the open or close sequence if the switch is still in position.
I'm not sure that's an issue, though, as I'm likely to not use DCS-BIOS for those levers because I can program the locks on the landing gear and flap levers to move automatically in a Pro Micro set up as a HID.

I've not tried anything else yet.

About the airspeed indicator:
Is the zero point straight down, and the end at "48" on the second rotation?

BTW, is there an easy way to convert the Common Data Km H airspeed from a string to an integer?  I want to use a common data heading and airspeed display, and it works better on integers.  Plus, I can convert that to MPH or Kn easily.


EDIT:
Just noticed gauge for the Long range tank isn't separated into left and right.
The cockpit gauges show them as split.

commondata has booth int and string.

 

The speed indicator i programed like i find its valves in the lua.

 

booth tanks are ther this gauge are the Central and longrange Fuel Gauges. i got my names from the lua.
 

i dint even start the plane i tested switches that read strange (in the lua) but deep testing are mostly the users that fly the plane. They know the functions better and i dont have the time to learn that much planes

 

If you find issues it would be great if you make issues via github

Thanks.  I didn't notice as the "simple" view shows a servo function by default.

Running into a strange issue with the F-14. I had lots of switches working through DCSFlightPanels, but since the last update most of these, but not all, have stopped working. All the other aircraft I have tried seem unaffected. Using the Chrome preview app it seems that the communication is only one way for a lot of these switches, the Chrome app can see the state of the switch, but it can't send a change to the F-14?

I know lots of us lost key bindings in the update, is it possible Heatblur changed some other things that may have broken this too. Can anyone confirm what I'm seeing?

[No1sonuk]

Was about to suggest going to the FlightPanels Fork Discord for notes on the update, but I see you've got your answer there.

I got some Dog Fight Boss -18 levers today and I’m trying to wrap my brain around this bios stuff. 
I downloaded the “flightpanels” .zip but what do I do with it, is there an installer I need to get somewhere? I see mention of the hub, is that the original software that is no longer updated? 
many help would be appreciated. 

EDIT:

Got the hub installed, and the dashboard shows connected with dcs and i can click the the "toggle" in the command library but the DFB levers arent being read.  I looked up the board and its on COM 4 and is connected, but dont know what to do from here.  

Also, i just dropped the whole dcs-bios branch file into the scripts folder of the saved games folder, is that it? and i also already had an export file for simshaker and just added the do file command on the next line after the do file for simshaker.  is that ok?

Hello!

I'm new to DCS-Bios, I'm just in the information gathering  stage.

My question is can I have output from a switch that have no feedback in the real cockpit?

For example: in the ka-50 the I have a switch for short/medium/long bursts. Can I make a 3 LED indicator that shows the corresponding position?

Or can I add an LED that lights up when the laser is switched on?

Thanks!

A few ways to make the burst indicators:
1) "Open loop" in hardware:
Use a double pole switch that uses one pole for the Arduino, and the other to switch on the LEDs.  This would be easy to make 2 LEDs work with a DPDT, centre-off switch, but a bit trickier for 3 LEDs.

2) "Open loop" in software:
Use a single pole switch for the Arduino and add a code routine that regularly checks the position of the switch and sets the LEDs accordingly.

3) "Closed loop" in software:
If you set the control reference view to "Advanced", you'll see there's usually a set of code lines for output on controls that have only input in "Simple" view. You could use these lines to read the state of the control as DCS sees it.
This would allow you to use the onscreen cockpit control, or any other bound control, and still have your LEDs work.

Open loop means you set the LEDs without checking if DCS responded to the switch.
Closed loop means you set the switch and read the feedback from DCS to set the LEDs.

As for the laser:
Is it any of these?
DcsBios::LED lwrLaserRange(0x1810, 0x0010, PIN);
DcsBios::LED lwrLaserTargeting(0x1810, 0x0020, PIN);

Thank you for your response!

I'm not yet programming, just gathering information whats possible.

Basically my question is that can I get feedback of the state of a switch that is just a flip switch and gives no feedback irl by switching on a light or something?

The laser part you pasted I think belongs to the "laser warning receiver" because "lwr" in the line, and thats gives feedback with lights in the cockpit too.

The ka-50s own laser, that is used for lasing targets is just an on/off switch that gives no feedback, you have to check its position by looking at it.

What I want to achieve is if I switch it on with a button on my hotas, then an led (on a led box) also switching on.

Also Id like to achieve to put 3 leds under each other, and if the burst switch is on short, then on led is on, on medium an other, on long, the third led is on. Also while this switch don't have a feedback irl.

Are these possible?

A suggestion: 
Start a fresh thread in this forum (home cockpits) for this question so we can keep this announcement topic tidy and go into detail in a dedicated thread.
I don't have the Ka50, so I don't know exactly which controls are used for the switches, but if you can give that info, or the DCS description of the switch, I might be able to find what you need.
Also include which DCS-Bios version you're using - I know the Flightpanels version has some additional features on some aircraft that aren't available in the Hub version.

 OLED and DCS bios when using with mega 2560 its work correct but when i switch to ESP8266 NodeMCU i get strange artefacts

Does DCS-BIOS support the use of a PCF8575 Expansion Module for Arduino?

[atkinson]

Hey! I'm new to this, but I've had little success. In general, the thing is ... Is it possible how to implement data output from the FC3 module. Specifically, they are interested in the lamps for retracting / extending the landing gear, flaps, brake flaps.

The FlightPanels Fork control reference only shows these:
Gear status            0-1
Weight ON Wheels Left Gear    0-1
Weight ON Wheels Nose Gear    0-1
Weight ON Wheels Right Gear    0-1
Left Speed Brake         0-65535
Right Speed Brake         0-65535

The numbers are the possible values.
There's no flaps value I can see.

DCS BIOS itself does not support port expanders.

You have to create your own instances for checking the input states from an expander and than send the command to DCS.

That`s how I plan to do the port extension on the VHF Radio Panel switches. I would apply the same logic to the PCF chips as I did for the MCP23017 expander.

The FlightPanels Fork control reference only shows these:
Gear status            0-1
Weight ON Wheels Left Gear    0-1
Weight ON Wheels Nose Gear    0-1
Weight ON Wheels Right Gear    0-1
Left Speed Brake         0-65535
Right Speed Brake         0-65535

The numbers are the possible values.
There's no flaps value I can see.

And it is possible in more detail? I'm not that experienced! I did not understand how to apply this data to the sketch. Or at least a sample, would be grateful.

Thanks Vinc_Vega

Thats what I thought.

Thanks for posting the code. I'm not much of a programmer, and new to arduino.

This sketch will turn on the built-in LED (on pin 13) when an FC3 aircraft gear is down and locked:

/*
  Tell DCS-BIOS to use a serial connection and use interrupt-driven
  communication. The main program will be interrupted to prioritize
  processing incoming data.
  
  This should work on any Arduino that has an ATMega328 controller
  (Uno, Pro Mini, many others).
 */
#define DCSBIOS_IRQ_SERIAL

#include "DcsBios.h"

/* paste code snippets from the reference documentation here */

DcsBios::LED fc3Gear(0x601a, 0x0400, 13);

void setup() {
  DcsBios::setup();
}

void loop() {
  DcsBios::loop();
}

DCS BIOS itself does not support port expanders.

You have to create your own instances for checking the input states from an expander and than send the command to DCS.

That`s how I plan to do the port extension on the VHF Radio Panel switches. I would apply the same logic to the PCF chips as I did for the MCP23017 expander.

I'm using a PCF8575 Module which uses P0,P1, etc as the names of the pins. Does this look right?

Also, 8575 did not recognize the pullUp command, so i removed it.
