学习笔记——计数器设计

开发板

`1、使用HX32OF28034PT 开发板，确定独立按键的输入管脚，将4个独立按键的引脚分别与开发板的gpio32，gpio33，gpio34， gpio39相连。将LED灯，扬声器，数码管作为输出引脚，与开发板的gpio32~gpio12相连。

2，遇到问题和解决问题
遇到问题：按下按键，对应按键的led灯亮起，松开按键则熄灭，而按下累加按键时扬声器响起的值与预定值不同，时而早时而晚，当扬声器响起后，再按下减数和复位按键是扬声器不停止发声。当时没有配置数码管驱动部分不了解计数值是否正确，而led灯亮计数不正确，推断计数部分出问题，只能加不能减，扬声器放声时间不对，应该是按键扫描中断出问题。
解决问题：采用delay定义一个空函数延时，再改为IF判断，delay，while对按键扫描，更改后按键扫描正常，计数器加减也正常。
