Detailed Description

template<class arg_pin>
struct bmptk::hardware::debounce< arg_pin >

debounce a pin_in

This template debounces a pin by keeping at least intreval time between reading the underlying pin. In other words: when the pin has been read less than interval time ago, it is not read again but the old value is returned.

Member Function Documentation

template<class arg_pin >

static bool bmptk::hardware::debounce< arg_pin >::get ( bmptk::time  interval = 50 * bmptk::ms )

inlinestatic

get the debounced state of a pine

If the previous reading of the underlying pin has been more than interval ago, this method will read and return the pin value. If not, it will rerturn the last value read from the pin.

The default interval of 50 ms will effectively debounce all switches and buttons, while still being unnoticable by humans.

template<class arg_pin >

static void bmptk::hardware::debounce< arg_pin >::init ( )

inlinestatic

initialize the pin as input

This method initializes the pin as input pin. This might involve configuring the pin as gpio, and disabling analog or other special functions.
