FlashGauge layout studio

Start from a layout

Load a dash.json to keep working on it — everything it contains is kept, even fields this tool doesn't edit — or start blank and build the whole layout here.

Opening a .fglayout unpacks it — the layout, its artwork and its fonts — so you can change one thing and export it again. It keeps the original layout's identity; use Remix as my own if you're publishing it as a new layout rather than updating that one.

Units

The dash converts every signal once, so speed, distance and temperature labels and needle ranges are all in these units.

Elements

Everything the dash draws. Add widgets here, then click one on the dial or in this list to select it — drag to place, arrow keys nudge (Shift = 10), Delete removes.

Background

Drag to move, scroll or use the slider to zoom. Only what falls inside the circle is visible on the dash, so frame it against the round edge.

Zoom 1.00× Smooth colour banding The dash stores 16-bit colour. Dithering hides the steps that photos of skies and gradients otherwise show. Send background as JPEG Sends the background compressed and lets the dash expand it, so the transfer is a few seconds instead of nearly a minute. The dash still stores full-quality 16-bit colour. Turn off only if a background looks wrong after install. Quality 85

Fonts

Add a TrueType or OpenType font, then the sizes you want. Each size becomes its own font file on the dash, holding only the characters its labels can show, so a big speedo font stays small. Use one by typing its name into a label's Font field; the files rebuild themselves as you change those labels.

Selected element

Coordinates are offsets from the centre of the screen. What an element shows on the dash is set under “Reacts to”.

What this layout needs

Taken from the artwork and fonts the elements name. Anything the firmware has built in is already covered; the rest has to be installed, or the dash falls back to its built-in layout.

Elements find their artwork at <name>

Files in this layout

Converted artwork, built fonts, and anything else the layout needs. Pre-built .bin images and fonts can be dropped straight in; a .ttf or .otf goes to Fonts.

Send it to the dash

Everything the layout needs goes into one file. Move it to your phone and choose it in the app's Update tab.

Export as separate files instead

For working over the wire with ftp1_send.py, or updating a single asset by hand.

Check a .bin file's header

Drop a working image file here to read its header. Use it to confirm this tool writes the same format your firmware already loads.

No file checked yet.

Vehicle settings

Per-bike numbers that live on the harness adapter, not in the layout: they stay with the bike when the layout changes. Export vehicle.json, then import it in the app's Vehicle tab and save it to the dash.
