Log Software

1. Change log

2. Design focus

2.1 Using Uart

• Connecting shield and odroid by uart communication.

  2.2 Handling all types of data

• Handling int, double, char, string types of data.

3. Concept design

3.1 Using Uart

• Using uart communication between shield and odroid.
• Easy to code with github opensource code “arduino-serial-lib”.
• Storing data simply using basic arduino library fuctions.

  3.2 Handling all types of data

• There are all types of DataStore functions.
• void DataStore(char data, char logname), void DataStore(double data, char logname), void DataStore(int data, char logname)

4. Detail design

4.1 log.cpp

※Please refer to ARL15-D-30-07-Software System_code manual(part log.cpp, DataStore.cpp, DataStore.h, arduino-serial-lib)

4.1.1 Using Uart

• We use “arduino-serial-lib”, github opensource code to connect odroid and Odroid shield. This code is based on the basic arduino IDE code, so it’s easy to use.
• Please refer the ARL15-D-30-07-Software System_code manual(arduino-serial-lib part) for more detail about the code

  4.1.2 Handling all types of data

• There are all types of DataStore functions. void DataStore(char data, char logname), void DataStore(int data, char logname), void DataStore(double data, char logname)
• It can also save picture data. When the odroid shield sends the string “cam” to odroid, log.cpp takes a picture and save it.

  4.1.3 More detail of DataStore

• When the odroid shield sends some data, it senses the data and save it as a “.txt” data.
• The name of the “.txt” file is the starting up time and date of the odroid.(ex, 20151123 13:12:33)
• It notifies the saving start point by storing “Odroid on” on the top of the file.
• When the odroid takes a picture, it saves the string “cam”, and the time of the moment

6. Results

6.1 Data

• We can save data which comes from odroid shield. The data storing form is same as the form which we mentioned before(4.1.3)
