Here is mine, it basically starts up with a loader, goes to terms of use screen and than goes to a screen where you can draw using a psp joystick while holding down a analog pin button:

to download tft library: sketch>include library> manage libraries>get tft.h and spi.h libraries

psp joystick x pin is analog pin 0
psp joystick y pin is analog pin 1
analog button pin is analog pin 5 with other contact on 5v pin
tft led pin on arduino pin 7 instead of 5v pin
sck pin 13
sda pin 11
a0 pin 9
reset pin 8
cs pin 10
gnd pin gnd
vcc 5v

This may be an interesting drawing program but I can't see any reason to call it an "operating system"

...R

3

Well it boots up, cant really call it an app like when its embedded on windows or something. I think the joystick script would make a good spot for a mouse cursor bitmap.

8bitbacon:
Well it boots up,

It would need to do a little more than that to become an Operating System.

"App" seems like a perfect name for it if you don't like the simple word "program".

...R

PS,. Introductory books on Operating System programming tend to be about 2 inches thick.

5

its an operating system if it were a question about who had more you are saying that something more than windows would mean windows is no longer an operating system but now an app.

6

8bitbacon:
its an operating system

is not.

Or if it is then the thing you eat your breakfast cereal with is a "garden-gate" rather than a "spoon".

...R

7

or if it is than your profile picture looks like the kit kat bar looking chip on the arduino uno and that's that

Whatever ... but your program is still not an operating system.

Successful computer program requires a high level of precision. Calling something by a name that is widely used by computer folks to mean something completely different is not helpful.

It is just distracting attention from whatever useful features your program actually has.
