ILI9486 touchscreen image upside down, how to rotate it?

[Mike - W4HOO]

Hi Craig, all,  I just added the ILI9486 3.5" touchscreen 480x320 display to my Digipi running on a Pi5. The image looks great, but it is upside down. I remember a post where you said to edit these two files:

Screen rotation is fully accomplished by editing two files,
direwatch.py  (packet/aprs modes)
digibanner.py   (other modes)

Most of the other screens, e.g. ST7789 already have a "rotation=XX" in their section of those two files, but the ILI9486 doesn't have rotation= in it's section. 

How to I rotate the output to that screen so that is right side up?

Also, can anyone recommend resource to learn about how to enable that screen when I'm not running DigiPi?  I also use this machine to run SVXLink node on Debian Trixie.

Thanks in advance for any help!

Regards,

Mike

SOLUTION FOUND: To rotate the DigiPi information screens on the Waveshare 3.5" ILI9486 display by 180 degrees (so it is right-side up in my application), update the origin parameter in your disp = ili9486.ILI9486(...) initialization block in each of the two files:  direwatch.py and digibanner.py

First, make the file system writeable with:

sudo remount.

Then use sudo nano filename (either of those below) to edit:

direwatch.py  (packet/aprs modes)
digibanner.py   (other modes)

default is: origin=ili9486.Origin.LOWER_RIGHT,

update to: origin=ili9486.Origin.UPPER_LEFT,

UPPER_LEFT flips it horizontally or vertically opposite to what I needed, you can also test these other origin settings supported by the library:

• ili9486.Origin.UPPER_LEFT (180° rotation relative to LOWER_RIGHT)

• ili9486.Origin.UPPER_RIGHT

• ili9486.Origin.LOWER_LEFT

Save the changes in nano by pressing Ctrl + O, hitting Enter, and exit with Ctrl + X.

Just to be safe I used the SAVE CONFIGURATION button in the DigiPi, then restarted the DigiPi and voila!  The DigiPi info screen now displays right side up.

73 all, Mike
