* NOTE: MS-DOS applications run on Trident adapters may not
be restored correctly when switched back to full-screen
mode from Windows.
** NOTE: MS-DOS applications run on some Tseng ET4000 adapters
may not be restored correctly when switched back to
full-screen mode from Windows. If this happens,
use Windows Setup to select one of the ET4000 options.
However, this may slow the operation of windowed

[L-ink]电子墨水屏NFC智能卡片
这是为了解决个人使用IC卡时遇到的一些痛点设计的一个迷你NFC智能卡，基于STM32L051和ST25DV。
想着既然要自制这玩意那就往炫酷了做，于是很自觉地把电子墨水屏也加上了，顺手也写了个配套APP用于显示内容定制。
摘要是个比较有意思的小项目，方案不算复杂，第一版设计也存在一些值得改进的地方，后续有空会继续优化方案设计的。

项目文件说明
硬件：来源里面是电路原理图和PCB文件，使用Altium Designer打开；释放里面是gerber文件可以直接发给厂家打样，也包含了元器件BOM表（部分IC不太可能可能要单独购买）。
固件：STM32L051的固件，我提供了Clion和Keil两个版本的工程文件，源码内容是一致的，分两个版本只是因为个人
