DCS BIOS Help

[Sting57]

Hi just trying to setup the ASPJ swtich on the hornet ECM panel.  I have my rotary switch all wired up

I am using the following code from DCS BIOS

 

const byte ecmModeSwPins[5] = {3, 8, 9, 11, 13};
DcsBios::SwitchMultiPos ecmModeSw("ECM_MODE_SW", ecmModeSwPins, 5);

 

However the switch does not work.  ( I have checked the controls and have no other buttons mapped to the ecm mode switch.

I have tested the switch on other functions (RADAR, DDI switch etc) and it works fine, so I know my wiring is all good.

Any idea's on why I am having issues with the above code?  Has DCS changed the naming of the function, if so how would i check?

 

Thanks

Sting

DCS doesn't control the name of the function.  AIUI, DCS-BIOS has a "lookup table" where it converts the name you use to an address and reads or writes to that address as appropriate.
That should remain the same unless you've update DCS-BIOS or the arduino library for it.

I would suggest setting up a completely separate arduino with just that function in it in order to test if any of your other code is interfering.  Isolate it entirely

it is the only piece of code in the sketch.  I wonder than if that internal "lookup table" has not been updated to the new switch?

LUA references for switches sometimes change with DCS updates. The ASPJ rotary and some of the ECM toggles changed recently it seems, so check that you have the latest version of the DCS-BIOS hornet module.

Ok just incase someone else finds this.  The Hornet plugin for DCS Bios is out of date with DCS.  To fix this issue:

 

I edited this file (the hornet plugin for dcs bios)

C:\Users\XXXXXXX\AppData\Roaming\DCS-BIOS\Plugins\module-fa-18c-hornet\FA18-C_hornet.lua

 

I changed this line

defineTumb("ECM_MODE_SW", 0, 3116, 248, 0.1, {0.0, 0.4}, nil, false, "Dispenser/EMC Panel", "ECM Mode Switch, XMIT/REC/BIT/STBY/OFF")

 

to this

defineTumb("ECM_MODE_SW", 66, 3001, 248, 0.1, {0.0, 0.4}, nil, false, "Dispenser/EMC Panel", "ECM Mode Switch, XMIT/REC/BIT/STBY/OFF")

 

And that is it.

 

This is the post that helped.  So Thank you BlackLibrary!!!

is it even possible to use Multiplexers with DC-BIOS???? does anyone have a working example? here is my sketch but its giving oscillation to the virtual cockpit buttons.

i think the readpanel() function is causing the MCU to write to the Tx pin and causing my problem so I need to make an if condition and compare anew state to the old state.
