IMPORTANT! NEW REPOSITORY!

We are now transitioning over to a new repository: https://github.com/Kav-Simulations
This is to accomdate our new natural integration with MobiFlight, and there is no longer any need for you to install our custom firmware or configuration files outside of MobiFlight.

All of our devices and firmware are now included in MobiFlight, and so the only need for our GitHub repository access is to contribute to development. If you are an end user, and don't need to contribute code, then you no longer need to follow our original installation guides.
Please visit our YouTube www.youtube.com/@kavsimulations5855 for the latest video tutorial on getting setup with our devices.

The original firmware will still be available for those that wish to continue using it, but it will no longer be supported or updated going forward. You can see the details below:

Jak Kav Custom Firmware

This is my custom firware for the MobiFlight modules.
It allows the user to use my custom LCD's for the FCU and EFIS.
There is a pre-built HEX file hardcoded with the pins detailed below
Current release is inline with MobiFlight V2.4.1, and you should use the file named mobiflight_mega_kav_2_4_1.hex, regardless of whether you're using just '1 FCU', '1 FCU and 1 EFIS' or '1 FCU and 2 EFIS'.

You need to put the arduino_mega_kav.board.json in your MobiFlight connector directory manually.
C:\...AppData\Local\MobiFlight\MobiFlight Connector\Boards\
You should then place the mobiflight_mega_kav_2_4_1.hex file in the C:...\AppData\Local\MobiFlight\MobiFlight Connector\firmware\ direcctory.
You can now simply click the Update Firmware button and ensure that the device shows Firmware 2.4.1 and the module type and name is MobiFlight Mega Kav.

It should be setup as a normal LCD DISPLAY from the 'Add Device' menu in the MobiFlight Modules settings page.

It will send a string as it's LCD output, and that will be converted to a method and value in the custom LCD library.
To use the precompiled HEX version, please connect to the following arduino mega pins:
FCU
CS = 12
CLK = 11
DATA = 8
Backlight = +5V

EFIS LEFT
CS = 32
CLK = 33
DATA = 34
Backlight = +5V

EFIS RIGHT
CS = 35
CLK = 36
DATA = 37
Backlight = +5V

If you wish to compile your own version with different pin numbers, you should change the values in LCDDisplayCustom.cpp in the Add function.
We have only compiled and tested for the Arduino Mega 2560 board.

In MFBoards.h, we have created this as a new board type, and this should be reflected in the MobiFlight Connector when setting up.
The devices should always be in this order, otherwise the data will be sent to the wrong device. This is critical!

MobiFlight-FirmwareSource

PlatformIO version of the MobiFlight firmware source.

To build:

1. Install Visual Studio Code
2. Install the PlatformIO extension. Visual Studio Code will automatically suggest this extension if you don't already have it installed.
3. From the Command Palette select PlatformIO: Build to build or PlatformIO: Upload to build and upload to your connected board

If you want to speed up local development and only build for one of the supported platforms then click on the Default (MobiFlight-FirmwareSource) label in the Visual Studio Code status bar and then select the specific target platform you want to build for.

Publishing a release

To publish a new release:

1. Go to the GitHub Releases page and click the Draft a new release button.
2. Click Choose a tag and create a new version tag, e.g. 1.14.0
3. Enter a title and release notes.
4. Optionally check This is a pre-release if the release should be for testing purposes and not be marked as the latest published release.
5. Click Publish release.

The release build process will automatically run and after a few minutes attach firmware binaries for the release to the release page.

If a release was marked as pre-release you can go back later and edit it to remove the pre-release designation which will automatically promote it to the latest published release.
