[原创] 【新版CH554评测-DIY】6.触控台灯（功能完成）

zhang7309 2018-5-23 22:32 楼主

查看之前的申请帖，发现时间显示功能未完成，因此本帖在上一贴的基础上进行改进完善

首先介绍一下触控台灯的功能：
可实现对LED灯的开关、调光控制，显示对当前按键的操作；
实时显示温湿度值，显示当前时间，并可对时间进行调整。

具体触摸按键功能如下：
板载K1、K2控制灯的开、关；K3、K4实现调光及调整时间；
LED开的情况下，按K3调亮LED，按K4键调暗LED；
LED关的情况下，按K3调整“时”（按一次，时加1）；按K4键调整“分”（按一次，分加1）

单片机资源使用情况：
P10温湿度传感器接口；P30LED驱动板（输出PWM信号调光）
P12、P32-P35外节LCD液晶模块；P14-P17板载触摸按键
调光控制利用单片机PWM输出功能，复用到P3口；
时间使用看门狗定时器产生秒时基，软件实现时间显示功能（时间会有一定的误差），
