This morning I had some spare time with my Bangle.js and I managed to upload and display a bitmap with 240x240 pixels and 16-bit colours.
Upload takes a while, but I wrote a web form, that does all the hard stuff for you. Displaying the whole bitmap takes approx. 2.2 secs on my Bangle.js.
Now I have to find out, how to write only parts of such an image in order to make it fast enough to be used as a clock background...
P.S.: yes, sorry, those web pages are still in German - trouble with files simply took far more time than I expected. Sorry - but I haven't forgotten all those enthusiasts without thorough knowledge of the German language...
