Hello All,
I have been working on various instruments for my Super Drifter for a couple of years. None of them Arduino-based. I have attached pictures before of some of those previous designs. I have stayed away from the Arduino mainly because of memory limitations when coding using a "sketch" (Basically C, a memory hog compared to my normal assembly routines) and the overhead of the bootloader. I decided to see what I could actually get accomplished and designed the attached Arduino-compatible printed circuit board to form fit it into a 2 1/4" inch instrument hole. Because I like graphic LCDs rather than straight text, the hardware had to accommodate the graphic LCD interface and I had to write the code to "talk" to the LCD. A feature rich character (various sizes) and drawing routines take up quite a bit Arduino's memory; however, many functions (like oil pressure and temp, EGT, etc are fairly easy to implement). Note the picture with the "live" graphics is not an Arduino-based design. If there is any interest, I'll post some updates as I build the next instrument based on the Arduino. I will be populating the PCB this weekend. Takes a bit of patience as most of the components are surface mount.
