【晒设计方案】简易计算器V1.00 [复制链接]

本帖最后由 ddllxxrr 于 2014-3-4 18:25 编辑

近两天用STM32F429i开发板搞了个计算器。原理如下：

1、用画图函数画出计算器的操作键盘。

2、用触摸屏程序去定位。根据定位采取相应的行动。

3、用到三个变量，一个记没有按操作符前的数值，一个记按操作符后的数据。结果在result变量中存储。


由于本人开发的为简易计算器。现在把操作顺序说一下：

点数字时稍快点显示出来了马上撒。按操作符号后显示清零。再按下一个数。

本次版本的计算器。只能到9999且不含小数。若超9999无论是操作数还是结果马上清零。决不姑息。




为了方便大家，我把主程序贴出。其实这个只要覆盖，触摸按键的例程就可以马上执行

希望后来的人少走弯路。再重申一下这是个初版，有些等修改，每次运算完必须按C清一下。

楼主搞得非常好！力挺！


不过楼主大量使用触屏的位置判断，如：

if ((TP_State->TouchDetected) && (TP_State->Y <= 100) && (TP_State->Y >= 50) && (TP_State->X >= 170) && (TP_State->X <= 220))

能不能将它使用运算的办法统一处理按键问题，得出123后就好办了
