我要做一个由按键和数码管构成的人机交互界面。下面是该界面的按键说明:1、进入参数设定菜单
a、长按“设定”键,直至显示“PASS”,表示要输入密码;
b、用“◄”键移动闪烁数字,用“▲”键修改闪烁数字,即可输入密码;
c、确认密码输入正确后,按“设定”键确认,即可进入参数设定菜单;
d、进入参数设定菜单后,用“▲”键可以选择菜单;
e、选择好菜单后,按“设定”键可进入该项参数的设置;
f、进入参数的设置后,用“▲”键可以选择参数值;
g、参数值修改完成后,按“设定”键确认修改,按“取消”键取消修改;
h、当各项参数修改完成后,按“取消”键退出参数设定菜单,即完成设置。
下面的程序是基于状态机的。我仅仅做到了把该显示的按照要求显示出来,但是如上面的说明,有些是给各个通道设置系数,有些是开启或者关闭某个通道。但是我不知道怎样告诉单片机,在我按下这个键时,就表明我开启了这个通道,设置了某个系数等等?总的来说我没有完成人机交互,这该怎么做?
问题2:这里面密码设置时需要按键来设置密码,我仅仅是一次显示出要设置的密码,做不到按一下,数字加1,设置完一位,在设置下一位,直到5位密码设置完成,这该怎么做?整个程序凡是需要按键动态设置的,我都没有做到。
问题3:下面的程序结构实在是太机械了,有没有更好的结构来实现?
