Shelly Pro 4PM display colors swapped

[phiten]

@gemu2015 the config file for the Shelly Pro 4PM is here: https://github.com/arendst/Tasmota/blob/development/tasmota/displaydesc/ST7735S_Pro4PM_display.ini

But the colors blue and red are swapped. Which values do I need to have a look at? Couldn't find docs for that.

[gemu2015]

try this: cmd 36 is RGB,BGR order
36,1,C8 -> 36,1,C0

[phiten]

That sadly didn't change anything.

[gemu2015]

yes i see, cmd 36 is overwritten in rotation code, clr bit 3 on all 4 rotations:

like this
R,36
:0,60,00,00,00
:1,C4,1A,01,01
:2,A0,01,1A,02
:3,00,1A,01,03

Awesome thanks that worked. Will push the changes in a moment.

Hey @gemu2015,

I realized that I may have made a mistake by enabling the dark mode by default here: da81d25

Because the LVGL switches are then purple instead of green e.g.

So in my local config I now reverted the change and trying to figure out the colors again. Maybe you could have a look again:
#000000 is white
#0000FF is yellow
#FFFFFF is black
#FF0000 is turquoises
#00FF00 is purple

[gemu2015]

internally we work with RGB565
i don't use LVGL don't know how LVGL translates to RGB565
20/21 is display color invert
and bit 3 of code 36 ist flip BR
so you have 4 permutations.
i would try all and compare with existing LVGL pictures

How did you flash the Shelly Pro 4PM with tasmota? Couldn't find any information on this.
