我做的万年历（m8 1302 18b20 1602）
mega8+1602+1302+18b20做的电子万年历编程环境是cvavr
还望各位高手多多指点
先上图

哦
这个是我是我使用涡流充电以后改的
所以禁止了时间的再次写入
写时间应为

wr_ds1302(0x82,0x59);

wr_ds1302(0x8e,0x80);
wr_ds1302(0x90,0xab);
} mark 日期后面再加个星期比较好。 刚刚完成1302的编程，正需要CV写的18B20程序，谢谢楼主。 我也是再弄按键程序啊 很难弄 楼主，wr_lcd_inf(1,223); wr_lcd_inf(1,'C'); 这是温度单位吗？223好像已经超出ASCII的值了吧？ 回复【19楼】gshuang1

233是是温度符号的那个圈，它与字母“c”组成温度符号 楼主:那个蜂鸣器下面的IC是做什么的? 与按键预处理有关? 回复【21楼】ldj7501
-----------------------------------------------------------------------
148是编码器，8线3线。
gs触发中断，中断扫描按键。 不错，顶一下。 楼主能否给下载器的资料我 真是强悍啊 顶 猛泰太！ 楼主，pcb能不能转一下格式啊，我用的protel99se打不开啊 mark 时间精确么 这个覆铜板做的太漂亮了 终于写完了
2级菜单+调时+温度报警+高低温记录+闹铃+闹铃设定+报警温度设定

楼主能不能重新发一份pcb的图啊，附件里的pcb没办法用，急用，感谢 LZ能发个原理图来看看，三极管是干啥用的？ 真不错。支持 回复【楼主位】b57203493
-----------------------------------------------------------------------
为啥我照做显示不了，能指教一下不 嗯哈 WANCHANG 调一下1602的电阻 实验成功，谢谢 看看 检测不到18b20,这是啥原因？ 回复【39楼】b57203493
-----------------------------------------------------------------------
检测不到18b20,这是啥原因？谢谢。。。 mark 排阻是10K还是470欧？？ 温度出来了，就是不变，问题挺多的，0.0 热转印做得很漂亮
