Toto je zatial len priebezne robena zbierka prikladov
-
Prvý program...
-
...bude vyzerať v simulátore takto.
basic.showIcon(IconNames.Heart)
from microbit import *
display.show(Image.HEART)

MicroBitImage Heart("0,1,0,1,0\n
1,0,1,0,1\n
0,1,0,1,0\n
1,0,1,0,1\n
0,1,0,1,0\n"); // 5x5 image
int main()
{
uBit.init();
uBit.display.print(Heart);
