Driver Display setup

This is a list of things I did to get the driver display app running on the raspberry pi + driver display:

Driver display + raspi setup

Follow the steps on the display user guide to set up the raspi config.txt file to work correctly with the display https://www.newhavendisplay.com/userguides/NHD-7.0-HDMI-N_User_Guide.pdf
connect the display via barrel to microfit adapter into a power source at 5V. It should draw ~0.6A when powered.

Flutter app building

Note: this step cannot be done on the raspberry pi because the flutter SDK doesn’t currently support ARM.

clone the telemetry_xiv repo onto the box.
Install flutter with sudo snap install flutter --classic
switch flutter to the stable channel with flutter channel stable, then flutter upgrade
cd into the telemetry repo, then run flutter build bundle
copy (via scp or otherwise; I used WinSCP) the folder MSXIV_Driver_Display/build/flutter_assets to the pi

Setting up flutter-pi

Flutter pi is the flutter engine used to run flutter natively on the pi. It’s repo is here: https://github.com/ardera/flutter-pi#running-your-app-with-flutter-pi

on the raspberry pi, clone https://github.com/ardera/flutter-pi.git
install the dependencies listed in the dependencies section of the repo’s readme. This step was surprisingly straightforward, so I’m not repeating them here.
run make in the repo folder
the binary created is flutter-pi/out/flutter-pi

Running the app on the pi

FLUTTER_ASSETS = the folder you copied to the raspi from the box
FLUTTER_PI_BIN = the binary created from the flutter-pi repo
There’s lots of options for flutter-pi, but the simplest command to run the app is:
$(FLUTTER_PI_BIN) $(FLUTTER_ASSETS)
