U8X8_SH1106_128X64 DRAW LARGE BITMAP? #2100

Open Beppi4U opened 1 year ago

Beppi4U commented 1 year ago

Hi! Is it possible to draw large Bitmap image with U8x8? Have already included U8x8 for Text but want to show a big Bitmap at start as a welcome screen! Use an Arduino Nano as Board There should be 4.5 Kbit left for the Bitmap after Sketch compiling. Isnt enough space for another Lib. Thanx for Helping! Andreas

olikraus commented 1 year ago

U8g2 is there for bitmap graphics. Of course you could also use u8x8 for graphics, but then you need to use the draw tile function and break down you picture into 8x8 tiles.

Beppi4U commented 1 year ago

Hi! Na... not an option! I tried to use both lib's and now i am afraid all i made is a bunch of Spaghetti code! Do i have to init the U8g2 to show it? Because it compiles and waits 3sec. but does'nt show the Bitmap! Would you min d to throw an eye on it? Rest works fine. Greetings Andi Sorry for ugly coding....my bad!

Ok, I stopped reading after the first view lines: do no use old u8g lib and u8x8 together. Use u8g2 only. U8g2 includes u8x8 (Use u8g2.getU8x8)

Mixing up libs is never a good idea. Thanx for help! Gonna try u8g2 out.
