More experimentation with Arduino and ILI9481 TFT screen.
The screen has an SD card slot which can be used for storing graphics.
Downloaded some weather icons in .png format, scaled them down and saved as .bmp files.
Those were loaded on an SD card.
Short demo:
I have also found a different library to control the screen. Much more versatile and faster than the previous one used. Unfortunately it can only recognise .bmp and .raw files so I lose the transparent backgrounds in the icon files.
Impressive.
ReplyDeleteWhen I get a minute I'll see if I can remember how I made clickable icons and the file format. It was years ago for an information centre and it was still going eighteen months ago. Can't recall whether they had an alpha channel or not.
