LCD BARgraphs

[Art]

Hi srspinho,

Unfortunately I have lost that code
In the end, for that project, I ditched both the graphing tachometer,
and the rolling odometer effect for the time display.
They both looked good on the desk where the project spent a couple of months,
but in the car, they both turned out to be a terrible idea.

I could see the peak on the tachometer graph, but not tell if it was the current
reading without looking hard, and the same with the elapsed time.
I went back to a plain vertical bargraph for the tachometer:



I do still have current code for the project that I wouldn't otherwise mind sharing entirely,
but I would mind spending the time making sense of it where it was not written for others.
It is only a collection of things available here, or substitutes for them done myself.
I did my own asm interrupts for example, but DT's interrupts do exactly the same thing.

I have an old project, where I´m already using 8 custom chars to show darrel´s bargraph, and other "compressed characters, like "Km/l" , "L/h".
Is it possible to re-use the custom char to show the odometer efect and this nice tachometer or this is not possible ?

I didn't read this correctly.
No, it is only possible to display eight at a time, you can only change the content of those eight locations an unlimited number of times.
otherwise it would be a full graphics LCD. THe elapsed timer in this one is only using six of them, the tach uses one, and there's a spare.
