如何编写程序，通过数字键盘（0-9）将0x12改成0x36
如题，考虑了很久，还是不知如何搞，现在的问题是ds1302修改时间，//顺序：秒，分，时，日，月，星期，年；格式：BCD
uchar times={0x50,0x59,0x23,0x06,0x09,0x01,0x15};
定义了一个数组，想通过键盘（0-9）修改一下时间，例如把times=0x06;修改为0x25，程序如何实现呢 temp=(read1302(reg)/16)*10+read1302(reg)%16读取转换成10进制
10进制转换成BCD写入write1302(reg,(temp/10)*16+temp%10) little_Monkey 发表于 2015-11-7 00:06
temp=(read1302(reg)/16)*10+read1302(reg)%16读取转换成10进制
10进制转换成BCD写入write1302(reg,(temp/1 ...
你还，仔细想了你的回复，你是将10进制转化为BCD码格式，我想问是通过数字键盘改变的1302数据么{:smile:} 1178951695 发表于 2015-11-7 11:09

读取到键盘如何得到数据那是你程序需要处理的问题，很简单了，最简单的方法，上次的按键值×10+这次的按键值 你是新手吧，这都搞不定，还是转行吧{:smile:} spring152 发表于 2015-11-7 12:25
你是新手吧，这都搞不定，还是转行吧
{:shocked:} ，发段程序来看看 #defineuchar unsigned char
uchar times={0x50,0x59,0x23,0x06,0x09,0x01,0x15};
uchar read_key(void)
{
// return key value
}
void chk_key(uchar key)
{
switch( key )
{
case 0: //key 0
times=0x25;
case 1: //key 1
case 2: //key 2
case 3: //key 3
case 4: //key 4
case 5: //key 5
case 6: //key 6
case 7: //key 7
case 8: //key 8
case 9: //key 9
default:
break;
}
}
void main(void)
{
uchar i;
i=read_key();
chk_key(i);
}
楼主要的不是什么把什么改成什么的程序，而是要一个通过按键设置时间的程序吧。 hyz_avr 发表于 2015-11-7 16:57

谢谢，你这的确可以变成0x25，但我需要的是通过按键2和按键5实现它，而不是人为的定义一个0x25，请问你还有其他的方法么 本帖最后由 hyz_avr 于 2015-11-7 18:10 编辑

楼上的为什么不给HEX文件？{:lol:} hyz_avr 发表于 2015-11-7 18:03
有，给你个十年前刚自学单片机时写的1602LCD电子钟程序。
牛逼，汇编啊 楼上的为什么不按我的需求，写一个C语言版的，求把源代码改好， 汇编看着太难了，看不懂，最好能把工程文件发出来，我一下到我的板子上就可以运行了！ 就是-段 十進轉十六進制程式而已! 上面已经有人说思路了,自己想想就好. 我觉得.提供思路已经是本坛极限了.还要帮忙改代码?又不是你家长…楼主自己考虑一下是不是适合做这样的事 伸手党……思路都说的很显著了……
那个贴汇编的哥们我觉得已经很显著要表达点代码之外的事儿了 既然你想要代码，而且要简单，呵呵
一按键，就把0x12改成0x36还不简单
if(KeyDownFlag)
{
if(Param == 0x12)
{
param = 0x36;
}
}
