一、leonardo最小系统 关于leonardo这里不再介绍,直接上最小系统原理图,该系统由atmega32u4制作完成。 按照原理图,搭建电路如下: 这里使用的是atmega32u4-AU TQFP44封装的,为了方便使用从网上买了个烧写底座,价格比较贵(某宝网200多元),建议大家在实验时,可以买转接板(某宝网不到2元一个),如下图: 二、烧写工具usbasp
连接成功后,对熔丝位进行设定,设定过程与晶振的使用有较大关系(具体如何选用请参考atmega32u4手册),这里先用默认的设置。 然后找bootloader,单击调入Flash,Bootloader在arduino IDE安装文件下的bootloader文件夹:arduino\arduino-1.6.5\hardware\arduino\avr\bootloaders\caterina\Leonardo-prod-firmware-2012-12-10.hex。

Compared with the earlier Arduino controllers, using the ATmega32U4 as its sole microcontroller, allows the Leonardo to be cheaper and simpler to use. Also, because the 32U4 is handling the USB directly, code libraries allow the board to emulate a computer keyboard, mouse, and more using the ...
