Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

RFID 智慧讀寫懶人模組

Readme

node-red-contrib-rfid-lazy

這是一個專為 Node-RED 設計的 UHF RFID 智慧讀寫懶人模組。

透過「大腦與手腳分離」的架構設計,本模組將繁瑣的 Modbus TCP 狀態機、Timeout 防呆機制與 Hex/ASCII 格式轉換完美封裝。開發者只需簡單接線,即可輕鬆實現工業級 RFID 標籤 (Tag) 的精準讀寫功能。

✨ 核心特色 (Features)

  • 全自動狀態機管理:內建讀取/寫入流程控制,自動處理設備忙碌與逾時 (Timeout) 防呆。
  • 高彈性記憶體操作:支援自訂寫入/讀取的起始位址 (Offset)執行長度 (Length),精準擷取所需區段。
  • 動態變數輸入:寫入數值支援多種資料來源,包含固定字串 (str)、動態訊息 (msg)、全域變數 (global) 與流程變數 (flow)。
  • 自動編碼轉換:底層自動處理字串與 16 進位陣列 (Hex Array) 的互轉,輸出乾淨易讀的 ASCII 字串。
  • 無衝突架構:不綁定實體 COM Port 或 TCP 連線,相容性極高。

📦 安裝 (Installation)

在你的 Node-RED 用戶目錄(通常是 ~/.node-red)下執行:

npm install node-red-contrib-rfid-lazy
