All, Please accept my apologies if I'm posting this question in the wrong forum. In any case, I would like to configure a matrix orbital or other LCD display to indicate automotive temperatures and pressures at once on an LCD screen. I like the matrix orbital ones because they are canadian (no duty to pay) and because I have one picked out that would go perfectly with my dash board colors. If I am not mistaken, most automotive electrical temperature and pressure guages are re-badged ohmeters. That is, the temperature/pressure sensor is either a heat sensitive or pressure sensitive variable resistor. A 12v+ current is applied to the gauge, and is then sent to the temperature/pressure sender which is installed in the engine block (ground/earth). Depending upon the resistance generated by the temp/pressure sensor, the gauge interprets the resulting variable resistance as a specific temperature or pressure. I would love to create an LCD display that would indicate oil pressure, oil temp, and water temp. I have a basic understanding of electronics fundamentals as well as experience with IC's, soldering etc. Can anyone give me an idea as to whether this project would be possible using a Matrix Orbital LCD display, what would be involved, and whether a NOOB like me should consider undertaking it? Thank you in advance for your thoughts. Regards, Jim
Yes it is possiable but would most likely require the use of a PIC, which requires a programmer and knoledge of the ASM programming language. oh, and tell us which screen you want..
Thanks for the response. I'd like to use screen number LK202-25-R Here's the link. http://matrixorbital.com/pages/product_view.asp?CatID=1&ProductID=51 How difficult is this programming. Can a guy like me with a dead-average brain figure this out?
Looks to be very well possible as MO displays are also used in non-PC environments. Their support forum is a good place to start.
