LCD ILI9341

Post by sswcharlie »

Hi

With the ILI9341 say set up with 12 rows of text data, say part numbers and 1 column
can it scroll down and select 1 of the rows and then replace that line with another slightly different, do this at the press of a button.
The list will show standard jobs for day. When job completed, select and press button.

So scroll down
Select row
Press button (which recognises which row it is in)
find in table the same job ref
delete original row
replace with new row (from the table/library)

If I could be directed to similar examples re scrolling, section button, table library, etc.

Thankyou
Charles Harris

The display itself can't do any of that. It has no concept of 'lines of text' or so on. It only knows "display this color at this pixel on this row".

You can program a microcontroller to manage the information structure you want, and to paint the ILI9341's screen in ways that represent the current state of the information structure and anything a control system might be doing to that state. Writing that code would be an intermediate-level challenge.
