Package com.codename1.hardware

package com.codename1.hardware

Buses and pins of embedded devices: GPIO lines (GpioPin, GpioListener), I2C (I2cDevice), SPI (SpiDevice), serial ports (SerialPort), PWM (PwmChannel), CAN (CanBus, CanFrame), the hardware watchdog (Watchdog) and backlight brightness.

Hardware.getInstance() is the entry point. Ports without hardware access report every feature as unsupported, so an application written against this package also runs on phones, desktops and the simulator.

Class	Description
CanBus	A CAN network interface, opened through Hardware.openCan(String).
CanFrame	One classic CAN frame: an identifier and up to eight data bytes.
GpioListener	Receives edge events from a GpioPin that was opened as an input with edge detection.
GpioPin	A claimed GPIO line, opened through Hardware.openGpioOutput(String, int, boolean) or Hardware.openGpioInput(String, int, int, int).
Hardware	Entry point to the buses and pins of the device the application runs on: GPIO lines, I2C, SPI, serial ports, PWM, CAN, the hardware watchdog and the display backlight.
HardwareException	Thrown when a hardware bus or pin cannot be opened or an I/O operation on it fails: the device node is absent, the process lacks permission for it, the line is already claimed, or the peripheral did not acknowledge.
I2cDevice	A device on an I2C bus, opened through Hardware.openI2c(int, int).
PwmChannel	A hardware PWM channel, opened through Hardware.openPwm(int, int).
SerialPort	A serial port in raw mode, opened through Hardware.openSerial(String, int, int, int, int).
SpiDevice	A device on an SPI bus, opened through Hardware.openSpi(int, int, int, int, int).
Watchdog	The hardware watchdog, opened through Hardware.openWatchdog(int).
