【开源】多功能称重器
1.介绍 正常的称重设备都只能计算物体的重量,输入价格计算出总价,这种设备比较单一,可能不太适合目前的多数应用场景,今天设计的一款多功能称重器他具有计价、计数和曲线功能,话不多说,我们来看一下怎么设计的。
2.硬件准备
3.设计 首先是设计素材,我采用Adobe Illustrator软件进行设计,本次设计没有其余控件,都是采用页面形式,素材如下。
第一个是首页,有产品标题和进入按钮,首页右上角会显示传感器的数值。
之后是菜单页面,菜单页面有四个选项,计价,计数,曲线和矫正,矫正功能主要是为了矫正传感器的基数。
来看看计价功能的界面,会显示重量、单价和总价,右边是对价格的一个输入,同时还有去皮按钮,进入计价界面时,会默认去皮一次。
再来看看计数功能的界面,这个功能主要是用于计算物品的个数,根据单个物品的重量来计算整个物品的个数,可以用于串串香的数签,或者计算硬币数量等。
最后就是曲线功能的界面,曲线功能主要是为了直观查看到物品挥发过程中的重量变化,比数字更加直观,可以用于一些科学研究的场景。
矫正功能就是矫正称重器的准度,因为不同的传感器会有些许的区别,所以需要进行矫正。
计价功能主要是重量的显示,价格输入的显示和总价的显示,主要代码如下: - //计价页面===================
- #define VALUATION_UNIT_PRICE_ADDR 0x1010
- #define VALUATION_GRAM_ADDR 0x1000
- #define VALUATION_TOTAL_PRICES_ADDR 0x1020

计数功能和计价功能类似,都需要进行数值的显示,不过不同的是需要计算物品的数量,计算物品数量的代码如下:

4.总结 这个项目让称重器的功能不再单一,可以根据使用场景进行功能切换,如果配合上国标的称重仪器,可以让产品更加正规完善。
