之前的触摸按键长按虽然可以用了
但是发现一个方便的方案把原有的
if(TK_zero > TK_cnt)
{
if((TK_zero - TK_cnt) >= T_KeyPress/4)
KeyState |=T_KeyState;
else if((TK_zero - TK_cnt) <= T_KeyPress/8)
KeyState &= ~T_KeyState;
}原先是/2 /3 通过修改为/4 /8 且屏蔽TK_zero--;以后 可以做到长按-即使长时间触摸仍然是正常的
但是随之移植到程序中出现一个问题,查询了规格书,STOP模式只能被中断或者触摸唤醒
但是实际的过程中当我看到指示灯亮起后 熄灭进入休眠模式 设备竟然能够自己唤醒 换设备 换芯片 仍然会有这个问题 怀疑是程序中某项配置的问题
但是对比了以往的休眠方式是一致的
即使有问题 STOP模式应该也无法自动唤醒才对
用回以前休眠的程序却能解决问题 是不是触摸的配置不能这么修改呢
