我们需要简单了解一下CH340C的作用,它主要的作用就是让USB信号转成芯片ATMEGA328P可以识别的串口通讯信号,属于一个信号处理站,作用就是让芯片知道USB发过来了信号,可是这个程序信号怎样按要求写入芯片的呢? 在nano组装好以后,厂家往ATMEGA328P的Flash空间内写入了Bootloader,写入Bootloader的空间是单独预留的,芯
在开始CH340C部分之前,先把AU封装的ATMEGA328P也烧写一下bootloader。 AU封装属于贴片,我买了贴片转接板。 反面焊上排针 额,本想着给这个AU芯片也上传bootloader的,结果刚通上电,成品板nano就冒烟了,这个丝…
1 在Arduino应用工具栏选择Tools > Processor > ATmega328P (Old Bootloader)工具 > 处理器 > ATmega328P (Old Bootloader)再次写入程序就会提示“上传成功”。

【nano简介】其实玩过Arduino的爱好者都知道,nano就是一块阉割版本的UNO——它去掉了vcc转5v以及电源自动切换电路,输入保护电路等。你可以这样理解,nano板就是一个Atmega系列单片机最小系统+一个烧录电路;国内生产的nano的烧录部分大多使用CH340类串口芯片。

PortB、PortC、PortD,后面会详细提到。单片机引脚数量有限,都是多个功能共同复用同一个引脚,通过软件配置来实现特定的功能。Nano板上引脚(1)(2)为串口输出输入引脚,板上通过CH340芯片转为了USB信号,方便主机下载程序、通信用。这两个脚尽量不做其它用途。系统功能引脚(3)(28)为系统复位引脚。 (4)(29)为信号地、...
