Can someone remind me how I clear a 2.9 inch e-paper Module that has random pixels set on it. I have run Peters clock program and it works ok but it only clears the pixels that are part6 of the fonts.

Worked it out. Got the brain cells to align.
> OPTION AUTOREFRESH ON
> FOR I= 1 TO 128: LINE I,1,I,296 : NEXT

Maybe premature victory. Even with BOX,1,1,128,296,,,FILL the screen is still grey in colour but running the clock program does leave the sections of the fonts as white.

Still may need some direction

Update:
FOR I=1 128:LINE I,1,I,296: PAUSE 100: NEXT
Seems to do the trick.

Just wanted to see what the new "Footnote" does.

It lets you add stuff after the thread has moved on.

Thanks Phil, I am still getting a grey background when I run the code even though the clock program does have a black to white transition during execution.

I would like to read what Peter said.

Palcal, I have done a search on Nucleo-l432kc and e-paper and came up with nothing, looked thru the threads around that time and I cannot find the original post.

Thanks Jim I've got that one but like OA47 can't find anything on a E-Ink clock.
I'm in the process of making a file with all the threads I am interested in so I can find them easily.

This bit of that link may be relevant to OA47's issue, the last sentence in particular.

Quote The displays are S.....L.....O.....W

A screen refresh on the 2.9" display takes just less than 3 seconds and somewhat over 5 seconds on the 2.7" display (note this is not significantly affected by the Basic code - re-writing in C wouldn't help). Also the displays flash from a normal image to an inverted one and back to a normal one as they refresh.
