Although the schematic of Leonardo is not published at this point, the design of Leonrdo must be straight forward, except the assignment of digital and analog pins.<\/p>\n The firmware and core codes for Arduino Leonardo are already in Arduino 1.0 RC1, which was published in September 17.<\/p>\n I decide to try Leonardo with Arafruit 32U4 breakout board+, as it also uses ATmega32U4.<\/p>\n You need to burn boot loader from Arduino 1.0 RC1. I use ISP programmer with the following steps.<\/p>\n Burn Bootloader 'Arduino Leonard' to 32U4 breakout board<\/p><\/div>\n<\/dl>\n<\/div>\n<\/dl>\n I open an example sketch named blink, then download the program to Leonardo.<\/p>\n Connect a LED to Pin13 (PC7) for blink example<\/p><\/div>\n <\/a> <\/dt>\n<\/dl>\n<\/div>\n The most interesting feature of Arduino Leonardo is the emulation of Mouse and Keyboard. One can make USB-HID class device with Leonardo.<\/p>\n I tried one of example sketch named JoystickMouseControl for the next step.<\/p>\n The following hardware setting is used for my trial.<\/p>\n wires to run JoystickMouseControl example<\/p><\/div>\n <\/a> <\/dt>\n<\/dl>\n<\/div>\n The following pins are assigned on Arduino Leonardo, according to the file (hardware\/arduino\/variants\/leonardo\/pins_arduino.h)<\/p>\n EOF<\/p>\n <\/p>\n Arduino 1.0 RC1\u304b\u3089ISP\u7d4c\u7531\u3067\u30d6\u30fc\u30c8\u30ed\u30fc\u30c0\u3092\u66f8\u304d\u8fbc\u307f\u307e\u3059\u3002\u66f8\u304d\u8fbc\u307f\u306f\u4ee5\u4e0b\u306e\u624b\u9806\u306b\u306a\u308a\u307e\u3059\u3002<\/p>\n Burn Bootloader 'Arduino Leonard' to 32U4 breakout board<\/p><\/div>\n \u30d5\u30a1\u30fc\u30e0\u30a6\u30a8\u30a2\u3092\u66f8\u304d\u8fbc\u3093\u306032U4\u30dc\u30fc\u30c9\u3092USB\u306b\u3064\u306a\u3050\u3068\u3001PC\u304b\u3089\u306fArduino Leonardo\u3068\u8a8d\u8b58\u3055\u308c\u307e\u3059\u3002<\/p>\n \u3042\u3068\u306f\u666e\u901a\u306bIDE\u304b\u3089\u30b9\u30b1\u30c3\u30c1\u306e\u66f8\u304d\u8fbc\u307f\u304c\u51fa\u6765\u307e\u3059\u3002<\/p>\n Examples\u306b\u3042\u308bBlink\u3092\u66f8\u304d\u8fbc\u3093\u3067\u307f\u307e\u3057\u305f\u3002<\/p>\n![\"32U4](\"http:\/\/morecatlab.akiba.coocan.jp\/lab\/wp-content\/uploads\/2011\/09\/IMGP5965-400x266.jpg\" "\\"32U4")
