AVR-Arduino与串口屏通信（电子秤例程）
本帖最后由 Aaron~ 于 2018-11-23 15:17 编辑1.开发板说明功能MCU ArduinoI/O 9路I/OLED 工作指示灯按键 复位按键电源 5V 电源输入
注：可实现的功能：a.称重，通过屏幕显示物品质量b.计价，通过屏幕显示金额d.校准称功能，可以随意更换称台
需使用的工具a. 硬件：arduino最小系统，HX711电子秤专用AD模块，电阻应变片式称台。b. 软件： Arduino 1.6.8。c. 原理图：详见“硬件原理图”文件夹。d. 程序：串口屏工程配置文件通过SD卡下载DWIN_SET导入屏中即可。arduino程序可参照arduino源码。
2.评估板硬件和软件部分详细介绍硬件接口定义TXD(屏端子显示) Tx1RXD(屏端子显示) Tx1独立按键 D3-D7HX711_SCK时钟信号 D11HX711_DATA数据信号 D10
