Plugin to read data from a program

[GiboAA]

Hello,
I am asking for help.
I have a Streamdeck plus that I would like to use to interact with a flight simulator, namely PSX: (www.aerowinx.com)
I have asked the developer of the PSX how I can make the Streamdeck "talk" with it and here is his answer:
https://aerowinx.com/board/index.php/topic,7420.0.html

Look at this picture:

For example, I would like the data presented in the 4 indicators circled in red to be shown on the 4 LCD displays of the Streamdeck plus.

I guess I need a plugin of some sort that allow to read these values in the sim and show on the SD LCD displays then.
How I can obtain this result ?

I guess these are the "commands" related to these indicators that you'll find in the "Network Documentation.txt" document below:

MCP SPD window

Code: Qi32
Name: McpWdoSpd
Mode: ECON
Range: 0 .. 1950
Add-ons can: Read only
Description:

When the value is greater than 950, the SPD window is blanked by the AFDS. The SPD window may also be blanked by the MD & T test. The Mach word and the Mach dot should disappear when the value is below 400.

MCP HDG window

Code: Qi33
Name: McpWdoHdg
Mode: ECON
Range: 0 .. 359
Add-ons can: Read only
Description:

The HDG window may be blanked by the MD & T test.

MCP V/S window

Code: Qi34
Name: McpWdoVs
Mode: ECON
Range: -80 .. 60
Add-ons can: Read only
Description:

The value represents hundreds of feet. When the value is 0, the hardware display should indicate "0000". In all other cases, leading zeroes should not be indicated on the display. Non-zero values should be preceded by - and + signs. The V/S window should be blank when the V/S mode is not engaged. Mode engagement can be checked by reading the variable McpPshVs (Qh69). This is the V/S switch with the in-built light. If the light contact is closed by the AFDS, the V/S window is not blank:

if ( McpPshVs & 8 ) == 0 then window is blank.

The V/S window may also be blanked by the MD & T test.

MCP ALT window

Code: Qi35
Name: McpWdoAlt
Mode: ECON
Range: 0 .. 500
Add-ons can: Read only
Description:

The value represents hundreds of feet. When the value is 0, the hardware display should indicate "00000". In all other cases, leading zeroes should not be indicated on the display. The ALT window may be blanked by the MD & T test.
