Hi, i currently have a 'TID' (tripple info display) in my corsa which displays info from my car sterio usch as track name or radio station etc. after playing about with an arduino and a 2x16 lcd display and making a clock i love the way this looks compared to teh standard screen in teh car i would like to be able to use another arduino and display (or use the current one i am using for a clock to siplay the information from my head unit. the pinout of the standard Vauxhal/opel unit is below
Pin # Name 1 Permanent 12V 2 Temperature – NTC Thermistor 3 Ground 0V 4 Temperature – NTC Thermistor 5 Accessories 6 Headlights 7 Dashboard illumination 8 Car-radio on 9 SCL 10 MRQ 11 SDA 12 Not connected (Speed)
i am a at a bit of a loss as of where to start on this one, i have no idea of how or what information is being sent to the display to even make a start on programming the arduino, any help would be greatly apprechiated.
As you acn see above some of the connections are used to display a temperature with a directly connected temperature sensor (i am happy to lose this function as my clock already incorporates this) and other pins are just to dim teh display if the headlights are on which i already have implemented so sont need thsi function.
Thanks and best regards,
