i want build altimeter: https://www.youtube.com/watch?v=mmimntv25bw. while waiting parts arrive, started looking on code. have splash.c file. code in file:

this splash screen when device boots, right? ( see yt link )

can explain means , how it's made? want create custom splash screen don't understand code. thanks!

i believe bitmap. values indicate draw pixel. 0x00 values blank space (probably black screen), , where there value greater 0 there pixels drawn (a 1 pixel). painted pixels come create image.

i think if search, should able find kind of editor let draw want , generate bitmap you.

java - UML - How would you draw a try catch in a sequence diagram? -

-
Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
