ST7796!

Hi MM!

Discover When I was making a counter, the number is not delete all when new number come. I mean if counter is shifting from 10 to 11 not all is deleted always after zero. I know I can use print " " for deleting but then the display "flicker" is there anything I can do so the 10 is complete delete?

Try simulate my program, same in real world.

I dont know if it is the same for ILI9488 an ILI9341.

One possible way to do it is to set the foreground colour the same as the background - re display the number then set colour to black again and display new number. This might be just as jarring visually as the 'space' technique?

Ben's buffered output might help - or use the technique I used to do a fast display and draw to a buffer on the mcu..

Hi,
It may not help but I normally print a space or two after the actual number.

Hi Martin and Bob!

Thank you for reply. It look like Martin´s examble work. But is it a bug?

I have added a counter.

Hi Jorgen,

How does it look on hardware? Is the 'clear' too noticeable? As Bob says - displaying a space (or spaces) after the number is a good way to handle this (but entails converting the number to a string first.
It's not a bug - it just occurs because the characters have different widths (a proportional font). So '1' is a lot narrower than '0'.

Hi Martin!

It’s the the same on display as in simulation. And yes I know there as different way to clear and I Will tast the best way. Thank`s to both of you
