Display Base Class

Classes

• Display: All display devices should inherit this virtual class,

class grove.display.base.Display

All display devices should inherit this virtual class, which provide infrastructure such as cursor and backlight inteface, etc.

Inheritance

backlight(enable=None)

Enable or disable the cursor on display device, not all device support it.

Parameters:enable (bool) – Optional, True to enable, Flase to disable. if not provided, only to get cursor status. Returns:backlight status, True - on, False - off. Return type:bool

cursor(enable=None)

Enable or disable the backlight on display device, not all device support it.

Parameters:enable (bool) – Optional, True to enable, Flase to disable. if not provided, only to get cursor status. Returns:cursor status, True - on, False - off. Return type:bool

grove.display.base.TYPE_CHAR

int(x=0) -> int or long int(x, base=10) -> int or long

Convert a number or string to an integer, or return 0 if no arguments are given. If x is floating point, the conversion truncates towards zero. If x is outside the integer range, the function returns a long instead.

If x is not a number or if base is given, then x must be a string or Unicode object representing an integer literal in the given base. The literal can be preceded by ‘+’ or ‘-‘ and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal. >>> int(‘0b100’, base=0) 4 .. code-block:: guess

0
