Minor appearance preference, but I added a line clear to the screen label display section:

void doCursorUpdateMain(void) {
	doMainScreenDisplay(); // call the appropriate display routine
	printStatusHold(findStr(displayFuncNames, screenCursor[(unsigned int)(mainScreenIdx)])); // briefly display screen name
	gotoXY(0, 1);
	clrEOL();
}

Thank you

Swap the 5 VDC and the ground connections, and you'll exactly have it.

Fair enough - that can be put in via an "#include," as well.

		if (!(timerStatus & tsButtonsUp)) { // see if any buttons were pressed, display a brief message if so

			j = buttonState;
			timerStatus |= tsButtonsUp; // reset keypress flag

			bpPtr = (PGM_P)pgm_read_word(&buttonPressAdrList[(unsigned int)(menuLevel)]);

			while (true) {

				i = pgm_read_byte(bpPtr++);

				if ((i == buttonsUp) || (j == i)) break;

				bpPtr++;

			}

			gotoXY(0, 0);
			if (j != buttonsUp) callFuncPointer((char *)(bpPtr)); // go perform action

		}

This is near the end of the code. The boldfaced things are the things that need changed.

Where have 5V, becomes GND, where have GND, becomes 5V, is correct?

Yep - That's also going into the code comments!

I've done it with that intention, is easier to intender.

Thanks, I'll add that as soon as I can. I didn't enable useSavedTrips so I don't want to loose my current tank data.

if (v2 == parms[CoastSpeedMin]) {d2 = tank.distance();}
cdistance = d2 - d1;
return cdistance;
}

This is my code, and it works , but with "canadian" version. So I think it should be rewritten for your version.

I've been testing the Multiplexed Analog buttons, and it works but not correctly, the first and third seem to do the same functions, as the middle button only changes the brightness, and pro comportace times as the first, the extra 1 to precionar appears (btn 8 pressed), the extra 2 has not tested because had no 47k resistance.
What is the tolerance of the resistors you used? I'm using resistors with 5% tolerance.
I think the problem I'm having now, has to do with the values ​​that each sends resistance, which may vary slightly and complicate the whole process, but at least I can see the system moving.

Thank you
