  1. HSCC-高速通訊與計算實驗室 撰寫Tiny OS – nesC Present:Li-der Wang 2012/3

  2. NTHU-高速通訊與計算實驗室 What is NesC ? • nesC：專為TinyOS設計的程式語言 • nesC is C-like programming language • Component-based • 程式是由一個個Component所組成 • Event-driven • 程式運作時是主要是用event來進行process

  3. NTHU-高速通訊與計算實驗室 Pragram Architecture • TinyOS把所有功能都包成一個個的component。 • 使用Interface作為呼叫底層Component 的方式 • Component包含程式實作程式碼 • Interface只有method讓使用者呼叫

  4. Pragram Architecture • 自訂的Component為主要控制程式(Main)，控制其餘TinyOS本身底層的Component • Component之間連結需要透過interface，所以要經過wired 主程式Component 中間經過Wired 所使用到的 Component NTHU-高速通訊與計算實驗室

  5. Pragram Architecture • Component 有兩種

  6. Example 1 ： Blink • C:\cygwin\opt\tinyos-2.x\apps\Blink • BlinkApp.nc • 為configuration檔 ，負責component之間的溝通 • Blink.nc • 實作的介面 for BlinkApp的定義 • 先進行 make octopus 編譯 • 完成後打入 make octopus docs 產生說明文件檔  C:\cygwin\opt\tinyos-2.x\doc\nesdoc\octopus\index.html 可以看到程式接線的實際情形

  7. Example 1 ： Blink

  8. Homework • 修改BlinkC.nc檔案，使其根據秒數來閃爍不同色的Led 燈, 4種燈 共16種變化
