it should look like this....

but the OLED show me this....

so where is my mistake?

Hope for help

[olikraus]

Invert bit order for each byte.

[ThorWallhall]

how to do this...... at the moment when i convert the png into the bitmap?

[ThorWallhall]

Sry...could you show me how?

[olikraus]

B00000111 becomes B11100000 Same for all other bytes. Obviously B00000000 Does not change...

[ThorWallhall]

AAAAHH....ok.....thanks a lot

[ThorWallhall]

but why does this happen?

[olikraus]

I do not know your converterbut with Gimp the result would be ok if exported as xbm.
