记录一次 CH340 arduino Nano 写入程序 报错问题及解决方法

[IoTSmartSensor]

问题描述

 

CH340 改版的非原装arduino Nano在写入程序时可能会报错，错误如下：

Arduino:1.8.19 (Windows 10), 开发板："Arduino Nano, ATmega328P"

项目使用了 6944 字节，占用了 (22%) 程序存储空间。最大为 30720 字节。

全局变量使用了502字节，(24%)的动态内存，余留1546字节局部变量。最大为2048字节。

Problem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

原因：Arduino AVR Boards 1.6.21 增加了对这些新电路板的支持，新的Nano板定义与旧的Nano和大多数第三方Nano不兼容。

解决办法

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”。
