【开源获奖案例】多功能称重器

                ——来自迪文开发者论坛


    本期为大家推送迪文开发者论坛获奖开源案例——多功能称重器。工程师采用4英寸COF智能屏，通过T5L OS核与HX711模块及5kg压力传感器套装进行数据交互，用户可轻松查看重量、单价、总价、去皮等计价显示功能，以及计数、重量变化曲线跟踪和称重器精准度矫正等功能，轻松切换不同应用场景，享受便捷高效称重体验。

 【演示视频】

                         


完整开发资料含迪文屏DGUS工程资料与C51代码，获取方式：

1. 前往迪文开发者论坛获取：http://inforum.dwin.com.cn:20080/forum.php?mod=viewthread&tid=10017&extra=page%3D1

2. 微信公众号中回复“多功能称重器”获取。

称重器实现计价功能的部分参考代码如下：

uint32_t valuation_unit_price = 0;    //单价
