ST7789 display

[medelec35]

That's great, thanks for letting me know.
Yes, that makes sense.
Just don't forget the ChangeBackground does not work until a ClearDispaly command is used.

[jandidden]

So background color is global on the whole display, and changing it needs to be followed by a ClearDisplay.
In contrast, changes in foreground color can be defined even on a pixel or any shape construct basis and does not need a ClearDisplay.
But I don't see any possibility to reverse a character that when it is white on black, change it to say blue on red.
That is not possible because you can't change background color locally. Or can you?

Jan

[jandidden]

Of course you can change background color locally: draw a rectangle or circle or ellipse and set transparancy and fill parameters appropriately.
So you can highlight a character in a soft keyboard by drawing a rectangle at the character position, printing the character in the drawn rectangle, giving it (the character) both a different background and forground color.
The original can later be restored to un-highlight it.
But when you have to highlight and un-highlight a string of characters (like when entering a password) you end up with a whole buch of different color rectangles all over the display, and I'm not sure what the impact of that is.
Probably need to reset the whole display to an initial layout after finishing the string selection procedure.

Thinking about it, ClearDispaly is only required for the background.
Not required for the foreground.
What about the attached project?

[jandidden]

I leaned another trick: that 'Toggle' function is neat. Thanks for that.
The blinking is nice but I believe it isn't prominent enough, especially on the small display. Maybe blue would be better, but reversing the background/forground is really noticeable.

[medelec35]

You're welcome.
Ah, I get what you are saying.
In that case what about the attached version?

[jandidden]

That looks great, and is very close to what I initially wanted to do.
One more step gets me there: a reversing character, see attached

So it looks that you can do a change of background color without a ClearDisplay and that then has only an effect on the next print (or plot?) command?
Which, in hindsight, does make sense.

Jan

[medelec35]

Yes, but to change the whole background is where the ClearDisplay is required.
You are correct.
When you change colour, it's the next print/plot that is affected.
At least you know now it's doable without adding shapes.

[jan.didden]

Another brain-teaser (for me at least). I need to display an arrow-like element in the shape of a triangle.
Like for a down-pointing arrow I'd have a small triangle with a horizontal base and two slanted down-oriented sides, see attached. Not a big issue, but I want to be able to fill such an arrow with a color as additonal indication, like green for underflow and red for overflow of a signal.
How do I do that flooding of the triangle?? FC9, ST7789 gLCD.

[jandidden]

Well. It compiled Friday, it doesn't compile Saturday.
I went back to the version that compiled OK, that didn't compile either.
Since ghosts do not exist, or so I thought, why the failure now?
Can anyone please look at the compiler output? (BTW is there a way to save the compiler output without having to do a global highlight of the output and save it in a text file?
BTW the sim runs fine. The failure is about halfway, building the object file:
