update a single value without first deleting the entire display

Stoni99

I just want to update a single value in the display. Is this possible without first deleting the entire display?

assuming you mean an LCD screen, a couple of possibilities come to mind:

draw a rectangle (using background color) over the old text
write a couple of spaces over the old text
rewrite the previous text with background color first

Thanks

@felmue often I use Serial.printf() function, with 90% of my application have the result I wanted! Also add the text background collor as the collor of the screen.
