Hi, everyone .
I have a question about MCP in xplane11 with zibo737

I used the config input for zibo 738 by Banzai.

example
#MCP SPEED switch
Command 0x6522 UINT8 1 0 laminar/B738/autopilot/speed_press _
0 0 laminar/B738/autopilot/speed_press

I used a tactile switches as input which in mobi pin #6 and a led as output which in mobi pin#7

the setup of tactile switche is
On Press
offset 0x6522
Int 1 bytes
value if($=1,0,1)
On Release none

When I first press, the plane mcp speed switch down , my mcp speed led bright

second press, the plane mcp speed switch up and light bright, my mcp speed led dark --> b737 speed action

third press , the plane mcp speed switch down and light bright, my mcp speed led bright

fourth press, the plane mcp speed switch up and light dark, my mcp speed led dark --> B737 speed inaction

I should press 4 times for speed action and inaction.

But in normal, only press 2 times for speed action and inaction.

Are there any error in my mobi setup ?

Hi

You give just the half information.....

What you show us is the config for the Switch.... And if i unserstand you the switch do what it should do ( Toggle the System on every usage from ON-OFF or from OFF-ON )

So what Offset do you use for the Output Config ? Do you use the same Offset ???

From my point of view these typ of Code you show is is the section to make "Inputs" via Internal Controll Events. ( A Verry Special System that is used for some Addons)
THIS Typ of Offsets are NOT used to read a information !

So i think for a Output Config you need another Offset ( and so another code line in the XPUIPC File) that finaly read the "LED Information" from the correct Xplane Dataref (Zibo Section) and support it to another free Offset!

I not own the File from Banzai.... But if he build it in a professional way he pretty sure also build the Output Offsets !



EDIT: After read the Text again.... Is it correct that also the Input is not work as expected ?..... Means a Single Press not toggle between the ON-OFF and it means you also neet to press it twice to execute a "momentary" press in the sim ..... means it need TWO Commands to get ON and another 2 to get OFF.
If this is correct then your Mobiflight Button also need a RELEASE with the Same Input Offset and Formula.
Means... If you press the Buttton momentary it send 2 Commands that represent the Press and Release of the Virtual Button in one sequence !

Hi

For the switch in Mobiflight you need to put
on press value 0
on release value 1
with the same offset number 1byte int

and for the led output you need another number offset who is read by Xpuipc with a different syntax like this example :

#MCP SPEED LED
Dataref SPEEDLED laminar/B738/autopilot/speed_status1 int
Offset 0x6511 UINT8 1 r $SPEEDLED

you ca find the dataref list for the output in the folder of Zibo 738

create an output config in mobi with this offset 1byte int and the pin #7
this work also whit 7seg display!

Thanks Banzai.

And sorry i not understand this master logic of the Input myself ( I thought you recommend this if($=1,0,1) yourself in case "axm823" try to use it.)

Sure.... Press 1 and Release 0 is much more logical and comfortable to use as my first aid solution to use the IF Statement for Press and release 2 times.
I´m a bit sad i not see this myself directly.

Thanks banzai and pizman82’s reply, and I’ll test tonight.

@ Banzai
A Additional Question/Idea.
Basicly not needed..... Just to optimize the code and reduce traffic.


The whole logic at the moment is executing the same command.... Whatever Offset swap from 0 to 1 or from 1 to 0.

Code:

#MCP SPEED switch
Command 0x6522 UINT8 1 0 laminar/B738/autopilot/speed_press _
0 0 laminar/B738/autopilot/speed_press 

If i understand right the problem is that there must be 2 commands to execute a virtual momentary action.... the first Press ( and hold) the button..... the second release it.
So Mobiflight need to send it 2 times ( In our case a 1 for press and a 0 fro release.)

**************
Question.... Is there a more effective way ?

Idea 1 Does there exist a alternate Event ?
You use "laminar/B738/autopilot/speed_press" ..... Is there also something like "laminar/B738/autopilot/speed_toggle"
So a event that execute the whole process in one command..... Means the Button get pressed and shortly behind released within one command !


Idea 2 Is it posible to line up 2 Commands within one condition ?
Something like ...

Code:

#MCP SPEED switch
Command 0x6522 UINT8 1 0 laminar/B738/autopilot/speed_press ; laminar/B738/autopilot/speed_press 
0 0 laminar/B738/autopilot/speed_press ; laminar/B738/autopilot/speed_press 

In that case Mobiflight would need to send only ON PRESS the Value if($=1,0,1) . And no release is needed in case this one command execute TWO TIMES the Zibo Command.

OK, Thanks Banzai & pizman82 's suggest.

That is what I test

#MCP SPEED switch
Command 0x6522 UINT8 1 0 laminar/B738/autopilot/speed_press _
0 0 laminar/B738/autopilot/speed_press

#MCP SPEED LED
Dataref SPEEDLED laminar/B738/autopilot/speed_status1 int
Offset 0x6511 UINT8 1 r $SPEEDLED

It work fine.

And I used a toggle for switch.
on press value if($=0,1,0)
on release value none
But pizman82's suggest 1 replace press by toggle is nothing when I press.
