Side project | Matlab & Arduino Serial Communication and Real-time Display Waveform

There are two part in this system. One is 'Arduino', the other is 'matlab'.

• Arduino : real-time sensor data collection, Acuator command(like motor).
• Matlab : get/save date from arduino, analysis and polt figure in time domain and frquency domain.

1. Arduino

1.1. Desired feature

• Data input : sensor data collection.
• Data output : Acuator command, like motor.

1.2. Basic function

1.2.1 ISR Timer

用途：因為要做傅立葉轉換，因此'Arduino' 需要固定時間間隔抓取資料。

• Arduino Timer Interrupts
• Arduino Interrupts

1.2.2 critical section

用途：使用 'Arduino' Timer 抓取資料，怕發生 ‘race condition' ，使用critical section進行動作保護。

• Arduinor referece. interrupts()

1.2.3. seven display

用途：建立 'Arduino' 時鐘顯示功能，用來除錯。

• 四位數七段顯示器

1.2.4. data structure

用途：在 'Arduino' 使用 C++，建立感測器資料佇列，儲存感測器資料。

• queue for arduino

2. Matlab

2.1. Desired feature

• Data input :
  • Connenct serial communication vie usb.
  • Get raw date from arduino.
  • Plot figure immediately with raw date in time domain.
  • Save raw date.
• Data analysis :
  • analysis and
  • plot figure in time domain and frquency domain vie data from arduino raw data.

2.2. Basic function

2.2.1. Matlab & Arduino Serial Communication

用途：Matlab 使用 USB 跟 Arduino 建立串列通訊

• Mac OSX Yosemite no serial ports showing for Uno R3
• Simple Matlab & Arduino Serial Communication
• 用Matlab與Arduino的序列阜溝通
• Serial Communication between MATLAB and Arduino
• Read Streaming Data from Arduino Using Serial Port Communication

2.2.2. Timer in GUIDE

用途：在 MATLAB 使用 timer 來持續更新即時動作。

• MATLAB: How to close a MATLAB GUI by using count down timer
• creating a timer in GUI
• MATLAB

2.2.3. save data dialog

用途：儲存 Matlab 蒐集到的 Arduino 資料。

• matlab GUI中uiputfile保存文件
• 列印函數FPRINTF
