TM1628 测试没有问题  gcc avr 网络上的程序经过更改把里面的数据位更改过，，，自己用的时候请自己更改查表值

......好久没有看了，，看看啊

就是判断时间

wjjcyy · 发表于 2012-2-6 08:27:17

测试按键的读中,,,,,等待测试.....

楼主能附带电路图么？

按键读取．网络上都有有的，，但这个可能要更改点东西．．

/*******显示的定义*/
//读取按键值并存入KEY[]数组，从低字节开始，从低位开始----
void Read1628_key(void)
{
  uchar i,j;
   STBIO|=(1<<STB);
   STBIO&=~(1<<STB);
Write_sm1628_byte(0x42);

   PC_DDR &=~ (1<<7);//内部上拉

   for(j=0;j<5;j++)//连续读取5个字节
{
      for(i=0;i<8;i++)
   {
      KEY[j]=KEY[j]>>1;
      CLK2IO&=~(1<<CLK2);
         CLK2IO&=~(1<<CLK2);
   CLK2IO&=~(1<<CLK2);
   CLK2IO|=(1<<CLK2);
         CLK2IO|=(1<<CLK2);
   CLK2IO|=(1<<CLK2);
      CLK2IO|=(1<<CLK2);
      if(READKEYPORTBIT)
         KEY[j]=KEY[j]|0X80;
      }
}
   for (j=0;j<5;j++)
   {
   KEY[j]=~KEY[j];
   }
