Also, what settings would you like?
So far I have:
Maximum brightness - This is just a limit on the max brightness the display's backlight will output. You will wire the display up to the car's dimmer (if you want), and you can dim it with the rest of the lights in the car. But if it is too bright, you have to either use a resistor inline with the display's power source, or you can just use this setting to tone it down a little. Currently, there are 10 brightness levels from almost off to full bright. I can make it more or less... or even infinitely adjustable if you want, but the latter case will come later in a firmware update if it's really wanted.
LCD Contrast - Adjust the contrast of the LCD screen from 1-20. This is what allows you to see the screen easily at any viewing angle. This is done in the software. There is no hardware required.
LCD Color - This will not apply for single color backlights, but if you want an RGB or Green/Orange backlight to match your interior lighting colors, I will allow you to adjust R, G, and B individually in this menu. I think increments of 10 (0-255) for each color will suffice for now.
Alarm Temperature - Determines at what temperature to set the alarm outputs off. Currently it can be adjusted in increments of 25 from 1000-1800 degrees F (1832 F is the upper range of the thermocouple amp currently when wired up to 5 volts).
I was going to put the peak-and-hold clear function in here too, but I think I will do something different. Currently, the settings/menu access is from "Button A". If, during normal operation, the user presses "Button B," the LCD will display the highest temperature since the power to the hardware was cycled. If that same button is then pressed and held down, it will reset the peak and hold. Sound good?
What else do you want to be able to play with? There really isn't much else you could do except switch between F and C. I will consider that in the future. The nice thing is that any extra functionality will be user-up-loadable to the hardware as long as you have the appropriate USB cable and software (the software will be/is free).
