speedometer HUD

Speedometer HUD is a relative simple project than navigation HUD. The initial idea is a speedometer HUD and can fix speed error by GPS, but I think the project can split to two parts:

  1. Arduino (CanBus)
  2. Android (GPS)

The 1st and simple part: Arduino (CanBUS), it's speedometer HUD.

The 2nd part need use arduino to communicate to any android phone, fetch android's GPS speed.

Combine 1st & 2nd part, we can correct CanBus speed error by GPS, but the benefit is not obvious, so I stop developing 2nd part.

Speedometer HUD had two module:

  1. CanBUS parser
  2. GarminHUD controller

Fortunately, GarminHUD has been hacked:

So my remain job is parsing CanBUS, and calling the library to control GarminHUD, done!
