算是填了最先挖的VFD坑
最近pcb厂家神仙打架,为PCB普及做出了巨大贡献,到这事儿发生我也就开了两三次板,都赶上这个时间了,不开白不开!
不说了,上图!

方案和之前的除了驱动电路都一样,以前那个自己绕变压器的方案发热量太大了。但是那组电路参数照样可以用的。
这次pcb除了几处纰漏,灯丝高压应该直接改为负高压,还有就是pmos不知道为啥错位了,可能是拼版的时候不小心移动了。
至于程序方面大部分直接用,由于不想改显示驱动,grid和digit还是将错就错,加一步call transcode() 罢了。
改动比较大的就是ds3231的驱动,原来使用stm8硬件iic。这次一开始调试的时候总是卡在忙,以前也有这个现象,一怒之下直接改成软件iic。
把以前的驱动拿过来改改方法就成了。

主程序流程就是定时器中断产生节拍,然后去读3231,显示,以及串口命令解析
效果图:
这个屏比较长,pcb只画了10cm,设计时忘记考虑usb口了,短在里面难受!
安鑫那边应该还在卖。
这个月点了3个VFD屏,还屯了不少。中间快递丢了,重新花50+RMB重新买,都是泪,哭。
