So I'm playing with an Armmite F4 (STM32F407VET6, firmware version 5.051 as described in this topic) and I am seeing some perhaps undesireable behaviour with the 'text' command.

From the command line:

cls ' works fine
text 10,109,"test",,5 ' works fine
text 275,200,"test",,5 ' works fine, text vanishes off right edge
text 10,208,"test",,5 ' works fine, text at bottom of screen
text 50,209,"test",,5 ' oh no, text is completely gone!
text 50,220,"test",,5 ' hmmm, weird bits of text appearing at top of screen
text 50,230,"test",,5 ' different bits of weird text at top

for y = 100 to 250 : text 50,y,"test",,5 : next y ' well now, ain't that interesting!

That last line should help figure out what is going on.

Note I'm only using font 5 because it is large and easier to see the effect. Other fonts behave the same.

Do other flavours of 'mite behave similarly?

Regards.

Hi Vegipete

What size panel are you using?

I get the same with a 3.2" panel which is to be expected as the resolution is only 320 (H) * 240(V)

OK on a 7" display

Quite right, I should have specified my panel size.

I'm testing with a 320x240 panel in landscape mode.

Here is an image of the result of the last (loop) command I gave above:

Try the command with bigger screens but adjust the end of the y-loop to be just off the bottom of the screen. My goal was to position text part way off the right and bottom edges of the screen. The right edge works fine. The bottom edge does not.

For completeness, I must test the top and left edges too...

Yes, top and left edges seem to work fine.

Note all these tests are with the default alignment of 'left/top'.
