Download USB Host Shield Library and extract it to library folder in your Arduino directory as given in figure:1.Mount the Keyes USB Host Shield into your Arduino.This pad is used in advanced power configurations, described in Power Options section. It can be used as a second interrupt pin of MAX3421E. GPX pin is not used and is available on a separate pad to facilitate further expansion. See interface modifications section for more information. To undo the operation, a wire is removed and the jumper is closed. In case pin is taken by another shield a re-routing is necessary, a trace is cut and a corresponding pad is connected with another suitable Arduino I/O ping with a wire. Pads for SS and INT signals are routed to Arduino pins 10 and 9 via solder jumpers. MAX3421E interface pads are used to make shield modifications easier.INT and SS signals can be re-assigned to other pins (see below) SPI signals cannot. However, standard-sized Arduino boards, such as Duemilanove and UNO have SPI signals routed to pins 11-13 in addition to ICSP connector, therefore shields using pins 11-13 combined with standard-sized Arduinos will interfere with SPI. In this group, the shield in its default configuration uses pins 9 and 10 for INT and SS interface signals. Digital I/O pins 0-7, like already mentioned analogue pins are not used by the shield and provided only for convenience.
ARDUINO USB HOST SHIELD LIB SOFTWARE
Max_LCD library which is part of standard USB Host library software package uses some of GPOUT pins. They can be used for many purposes I use it to drive HD44780-compatible character LCD, as can be seen in digital camera controller circuit, as well as this keyboard example. GPOUT pins are eight 3.3V general-purpose digital output pins of MAX3421E.SCK, MOSI, MISO and RESET signals from this connector are used.

ICSP connector is used by the shield to send/receive data using SPI interface.An example of GPIN use can be seen in digital camera controller project. GPIN pins can also be programmed as a source of the MAX3421E interrupt. They are used primarily to interface with buttons, rotary encoders and such. Eight 3.3V general-purpose digital input pins of MAX3421E. They are provided to simplify mounting and provide pass-through for shields mounted atop of USB Host Shield in a stack. Analogue pins are not used by the shield.RESET, 3.3V, 5V and GROUND signals from this connector are used. Power pins are used to connect to power pins of Arduino board.See Power Options section for the Detailed explanation The configuration is shown, when both jumpers are closed, is suitable for official Arduinos, such as UNO, Duemilanove, Mega and Mega 2560. They are used for different power Configurations. Power Select 2 solder jumpers marked “5V” and “3.3V”. Mass storage devices, such as USB sticks, memory card readers, external hard drives (FAT32 The following device classes are currently supported by the shield: HID devices, such as keyboards, mice, joysticks, etc. Operates over the extended -40☌ to +85☌ temperature range Complies with USB Specification Revision 2.0 (Full-Speed 12Mbps Peripheral, Full-/Low-Speed Specifications Work with standard (dual 5/3.3V) and 3.3V-only (for example, Arduino Pro) boards.

No more SPI re-wiring and code modifications - just With the Standard variant of this shield out of the box. Thanks to new interface layout it is nowĬompatible with more Arduinos - not only UNO and Duemilanove but also Mega and Mega 2560 work This is based on revision 2.0 of USB Host Shield. On the MAX3421E (datasheet), which is a USB peripheral/host controller containing the digital logic andĪnalog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant The USB Host Shield allows you to connect a USB device to your Arduino board.
