一个 Node.js 模块，可用来读写和操作 XLSX 和 JSON 电子表格数据和样式(A Node.js module that can be used to read, write, and manipulate XLSX and JSON spreadsheet data and styles)

读写标签源码，可二次开发，是通过 PN532NFC模块串口连接电脑实现上位机操作对NFC卡读写操作。(Read-write tag source code, can be redeveloped, through the PN532NFC module serial port connected to the computer to achieve the upper computer operation on the NFC card read-write operation.)

基于PN532NFC模块与STM32F10x的通信源码，可实现对NFC读写(Based on the communication source code between PN532NFC module and STM32F10x, it can read and write NFC.)
