17年也没干个啥，年后就去折腾着玩意儿了，也不知道我折腾它还是它折腾我。反正总之现在勉强可以交作业了，呵呵
硬件：
1.罗耶振荡电路输出一路4v交流，一路25v交流
其中4v直接驱动灯丝，另一路经电桥整流提供负压给pt6311
2.主控用stm8s003f3
成本低廉，而且我这几块stm8是x宝掌柜送的，本身性价比也很高，8kflash先在用串口调试附带其他驱动大致用了
也就是大概用完了。其实去掉uart估计要少4k，我寻思加个gps解码的程序应该够用吧。。。23333
3.vfd驱动用前面提到的pt6311
我买的好像很便宜，1.85一片。但是现在用了三片，其中一片死活有个seg不输出。索性它便宜就不计较了2333

按键那部分单独做了块小板子，一来空间不够了，而来后期设计外壳更方便，总之有打印机是方便的很

复制代码懒得上main.c了，有心人一下子就搞出来了，我api都写的差不多了，剩下按键改时间，以及闹钟设置，可选的gps校时
注意stm8s_i2c.h这个头应该是11年那个比较大的头，起初那个不行，后来根据风驰的eeprom教程移植，它用的也是我说的这个新点的库
