This is a MobiFlight profile that allows you to use the Airbus MCDU with the Boeing 737-700. To work, it requires Python, along with the Python packages websockets, gql, and simconnect. It also requires the beta version of MobiFlight, as the current stable release does not support the Winwing MCDU.

Instructions
To start, be sure to download and install MobiFlight, link found below:
https://www.mobiflight.com/en/index.html

Once installed, go to Extras, Settings, then checkmark under the 'Beta Versions' section, "Yes, I would like to receive beta version updates". Select 'OK' then close MobiFlight and reopen. Upon reopening, it will present you with the prompt that there is an update. Allow it to update, then reopen. After the install and reopen is complete, close the application.

Now you will need to install Python, if it is not installed on your machine already, and then install the packages. Instructions are on the link below:
https://github.com/MobiFlight/MobiFlight-Connector/wiki/Installing-Python

Once Python and packages are installed, you can reopen MobiFlight. Unzip my file and place the MobiFlight profile file '737-700.mfproj' where ever you would like to store it. In MobiFlight, you can go to File, Open, then select my profile "737-700.mfproj". You can boot up the sim, load into the plane, get power to the plane so the MCDU can be on in the sim, THEN open MobiFlight and press the play button in MobiFlight. MobiFlight should not be open or running until their is power to the plane. If it still continues to not show the screen, try closing and restarting MobiFlight and pressing play again. You may also need to get into the FMS screen to "jumpstart" the screen.

I have noticed if you have MobiFlight running before their is power to the plane, the screen will not turn on, but the buttons will work. I assume this is a bug with either the python packages or MobiFlight beta.

PLEASE NOTE:
As per the instructions on github site:
Do not run SimAppPro in parallel. After using SimAppPro unplug and replug device to USB port.


Button Details:

All the number, letter, BRT and DIM, and L1-12 keys are the same as the Airbus MCDU. I also made the '/' and the "SP" key the same. Below are the changes to the other keys:

WinWing Airbus MCDU -> PMDG 737-700 FMS
DIR -> INIT REF

PROG -> RTE

PERF -> CLB

INIT -> CRZ

DATA -> DES

F-PLN -> MENU

RAD NAV -> LEGS

FUEL PRED -> DEP ARR

SEC F-PLN -> HOLD

ATC COMM -> PROG

MCDU MENU -> EXEC

AIR PORT -> N1 LIMIT

Blank key next to AIRPORT -> FIX

Right Arrow -> PREV PAGE

Left Arrow -> NEXT PAGE

OVFY -> DEL

Hope this helps you a bit. Please note that I did not create the github package or MobiFlight beta, so I am unable to fix the bugs that they may present. Please be kind :)
