51单片机。1302+12864成功设置一组定时，定时时间到报警。能显示第几组定时，但是只能成功设置一组定时时间。单片机掉电重启后lcd就会复位。程序注释还不够全面。-51 single. 1302+12864 successfully set up a regular, regular time to the alarm. Can display the first few groups of timing, but only successfully set up a group of regular time. After the device is powered down reboot lcd is reset. Program notes are also not comprehensive enough.
