\class Gpio
\brief The Gpio class allows to interact with the GPIOs.
\ingroup hardware
\inmodule libnymea
A "General Purpose Input/Output" (GPIO) is a flexible software-controlled
digital signal. They are provided from many kinds of chip, and are familiar
to Linux developers working with embedded and custom hardware. Each GPIO
represents a bit connected to a particular pin, or "ball" on Ball Grid Array
(BGA) packages. Board schematics show which external hardware connects to
which GPIOs. Drivers can be written generically, so that board setup code
passes such pin configuration data to drivers
(\l{https://www.kernel.org/doc/Documentation/gpio/gpio.txt}{source}).
General Purpose Input/Output (a.k.a. GPIO) is a generic pin on a chip whose
behavior (including whether it is an input or output pin) can be controlled
through this class. An object of of the Gpio class represents a pin.

\class GpioMonitor
\brief The GpioMonitor class allows to monitor GPIOs.
\ingroup hardware
\inmodule libnymea
An instance of this class creates a thread, which monitors each of the added GPIOs. The object
emits a signal if one of the added GPIOs changes its value. The GpioMonitor configures a GPIO as an
input, with the edge interrupt EDGE_BOTH (\l{Gpio::setEdgeInterrupt()}{setEdgeInterrupt}).
\chapter Example
Following example shows how to use the GpioMonitor class for a button on the Raspberry Pi. There are two possibilitys
to connect a button. Following picture shows the schematics:
\image Raspberry_Pi_Button_Example.png "Raspberry Pi button example"
Button A represents a clean solutin with a 10 k\unicode{0x2126} resistor (set up as activeLow = false).
Button B represents a "dirty" solution, were the 3.3V will be directly connected to the GPIO if the button is pressed (set activeLow = true).
Here is the code example for a button class:
\code
Button::Button(QObject *parent) :
QObject(parent)
{
m_button = new GpioMonitor(110, this);
connect(m_button, &GpioMonitor::valueChanged, this, &Button::stateChanged);
}
bool Button::init()
{
return m_button->enable();
}
void Button::stateChanged(const bool &value)
{
if (m_pressed != value) {
m_pressed = value;
if (value) {
emit buttonPressed();
} else {
emit buttonReleased();
}
}
}
\endcode
