Detailed Description

template<typename...>
class bmptk::hardware::tee<>

one out_pin that represents any number of pin_out's

This class template is used to construct a single out_pin class from any number of specified downstream out_pin classes, or from all pins in an out_port. Calling init() or set() on the tee class causes the corresponding method to be called for all downstream out_pin classes (or for the underlying out_port). Hence the effect is that one out_pin can represent a bunch of out_pin's, as if they were fitted together using tee fittings.

A tee with zero parameters is a kind of dummy point: you can cann init() and set() on it, but to no effect at all.

The typename template arguments must be classes that are descendants of pin_out, or a single class that is a decendant of port_out.

Example (examples/db103/wiggle/main.cpp):

// show a 'wiggle' pattern (= alternating 0xAAA and 0x555) on 12 LEDs

#include "bmptk.h"

typedef bmptk::hardware::tee<
                            bmptk::target::gpio_0_4,
   bmptk::hardware::invert< bmptk::target::gpio_0_5 >,
                            bmptk::target::gpio_0_6,
   bmptk::hardware::invert< bmptk::target::gpio_0_7 >,

                            bmptk::target::gpio_1_0,
   bmptk::hardware::invert< bmptk::target::gpio_1_1 >,
                            bmptk::target::gpio_1_2,
   bmptk::hardware::invert< bmptk::target::gpio_1_3 >,

                            bmptk::target::gpio_1_4,
   bmptk::hardware::invert< bmptk::target::gpio_1_5 >,
                            bmptk::target::gpio_1_8,                         
   bmptk::hardware::invert< bmptk::target::gpio_1_9 >
