三星9位段码VFD_ESP8266主控时钟实现

三星9位段码VFD_ESP8266主控时钟
最终效果
还是不出的哈哈哈,电路分为两块,VFD显示部分以及ESP8266主控部分。
硬件介绍
显示屏
图片均来自淘宝,因为已经没有VFD变压器提供了,所以我使用了没有变压器的VFD驱动电路。
VFD驱动
VFD驱动我使用了专用驱动IC-PT6312,需为此IC提供负高压(-20V以上)以驱动VFD栅极,以及提供灯丝的交变电压。
VFD电源电路
经过我不懈的努力在网上找到了,一个无变压器产生负压以及灯丝交变电压的电路:网站,有能用的当然是买过来啦,一块钱可以接受。
“本电路采用廉价的音频功放集成电路,通过文氏电路自激震荡,低压下能输出符合驱动灯丝要求的交流电源;同时利用高集成度的高频boost-bust驱动电路产生负高压驱动栅极,电路非常简单,无需调试,即可生成驱动VFD的三路电压,通过改变采样电路分压电阻,能适配不同电压要求的VFD屏。整套电路成本非常低,不用采用变压器,能达到93%的驱动效率,适合推动绝大多数负高压的VFD电路。”

VFD显示屏部分电路图
因为使用ESP8266作为主控,IO不多,PT6312正好可以控制4个LED,以及按键检测,于是直接将这些集成到VFD显示板上了。
ESP8266主控板
电路好像没啥特色哈哈哈,就不多讲啦。这里使用ETA6093的原因是我本来想使用电池的,但这个系统耗电量还是挺大的,接电池不能工作很久(就几小时),钰泰ETA6093三合一SOC电源管理芯片,支持1A开关充电,1A同步升压,充放电效率高。SOT23-5小型封装,集成度,外围少。搭配USB-C接口使用,可以做C口充放电功能。
代码介绍
写代码当然是Ctrl+C,Ctrl+V啦,能不用自己写的就一点也不自己写,这里使用ArduinoIDE编写ESP8266代码,以前一直不怎么喜欢Arduino(真香),疯狂使用别人的库就行啦,哈哈哈。
大量代码参考自(拷贝自)单片机菜鸟哥的ESP8266 Arduino教程
NTP网络校时代码则来自B站的一位大神的开源项目代码。
主要实现功能
这里偷懒直接截图一下我写的使用说明:
配网
这里使用的是SmartConfig配网,可以在乐鑫官网下载安卓或者苹果对应的配网软件ESP-TOUCH进行配网(配置连接的WiFi信息)。
当然有兴趣的话,我推荐使用单片机菜鸟哥的ESP8266 Arduino教程里的wifimanager配网。
全部源码
很乱哈哈哈,就随便写写的,也没怎么整理,可以看到我原来使用的是红外控制,后来发现PT63212可是外接按键,就使用了按键控制了。
