Pour commencer

To get started, simply connect the board to power with the 5V AC-to-DC adapter and then connect to the computer with the micro-USB cable. By default they measure from ground to 5 volts.

 

Brochage

I2C bus, TWI

SDA and SCL pins that are near to the AREF pin.

TWI: A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire library.

Bus SPI

Defaults to 4MHz to support Arduino Uno shields. sing the board.

Compatibilité des broches Arduino Uno Rev3

Arduino Shield Supported Features Galileo is compatible with Arduino UNO shields and is designed to support 3.3V or 5V shields, following the Arduino Uno Revision 3, including:

  • 14 digital input/output pins, of which 6 can be used as Pulse Width Modulation (PWM) outputs;
    • Each of the 14 digital pins on Galileo can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
    • They operate at 3.3 volts or 5 volts. Each pin can provide a maximum of 10 mA or receive a maximum of 25 mA and has an internal pull-up resistor (disconnected by default) of 5.6k to 10 kOhms.
  • A0 – A5: 6 analog inputs, via an AD7298 A-to-D converter
    • Each of the 6 analog inputs, labeled A0 through A5, provides 12 bits of resolution (i.e., 4096 different values). By default they measure from ground to 5 volts.
  • I2C bus, TWI: SDA and SCL pins that are near to the AREF pin.
    • TWI: A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire library.
  • SPI:
    • Defaults to 4MHz to support Arduino Uno shields. Programmable to 25 MHz.
    • Note: While Galileo has a native SPI controller, it will act as a master and not as an SPI slave. Therefore, Galileo cannot be a SPI slave to another SPI master. It can act, however, as a slave device via the USB Client connector.
  • UART (port série): Programmable speed UART port (digital pins 0 (RX) and 1 (TX))
  • ICSP (SPI): a 6 pin in-circuit serial programming (ICSP) header, located appropriately to plug into existing shields. These pins support SPI communication using the SPI library.
  • VIN: The input voltage to the Galileo board when it's using an external power source (as opposed to 5 volts from the regulated power supply connected at the power jack). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
    • Warning: The voltage applied to this pin must be a regulated 5V supply otherwise it could damage the Galileo board or cause incorrect operation.
  • 5V output pin: This pin outputs 5V from the external source or the USB connector. Maximum current draw to the shield is: 800 mA
  • 3.3V output pin: A 3.3 volt supply generated by the on-board regulator. Maximum current draw to the shield is: 800 mA
  • GND: Ground pins.
  • IOREF: The IOREF pin on Galileo allows an attached shield with the proper configuration to adapt to the voltage provided by the board. The IOREF pin voltage is controlled by a jumper on the board, i.e., a selection jumper on the board is used to select between 3.3V and 5V shield operation.
  • Bouton/broche RESET: Bring this line LOW to reset the sketch. Typically used to add a reset button to shields that block the one on the board.
  • AREF is unused on Galileo. Providing an external reference voltage for the analog inputs is not supported.
    • For Galileo it is not possible to change the upper end of the analog input range using the AREF pin and the analogReference() function.

Fonctionnalités supportées par l'architecture Intel

The genuine Intel processor and surrounding native I/O capabilities of the Clanton SoC provides for a fully featured offering for both the maker community and students alike. It will also be useful to professional developers who are looking for a simple and cost effective development environment to the more complex Intel® Atom processor and Intel® Core processor-based designs.
