This is the code for the Carloop demo at World Maker Faire 2016 in New York: a dashboard from a car that is controlled through Carloop.
The main program reads 3 knobs (engine speed, vehicle speed and engine temperature) and transmit CAN messages with those values to control the dials in the the dashboard.
A car pedal was added for Bay Area Maker Faire 2018.
The Carloop also interfaces a Linux laptop or Raspberry Pi running
canutils, a suite of program for car hacking.
The 3 knobs must be connect this way:
-
Connect the top pin of each knob to common power.
-
Connect the bottom pin of each knob to common ground.
-
Connect the middle pin of each pin to different signal wires
-
A2: common power
-
A3: common ground
-
A4: engine speed signal
-
A5: vehicle speed signal
-
A6: engine temperature signal
