RST-04: Buttons

Lesson

• review Python Bitwise Operators

  • x & y -> Does a "bitwise and". Each bit of the output is 1 if the corresponding bit of x AND of y is 1, otherwise it's 0.

• see an example of how to use the uGame buttons below

• Note: 

  • there are a max of 8 buttons and each one gives a 1 on an 8-bit number!

  • For example:

    • 00000000 - no buttons being pressed

    • 00000001 - B button being pressed

    • 00000010 - A button being pressed

    • 10000001 - Left & B buttons being pressed
