SerialPort is a library from [Bill Greiman’s beta library](https://code.google.com/p/sdfatlib/downloads/list).
|
||||
|
||||
OpenLog currently uses the 20120106 version.
|
||||
|
||||
Unzip ‘SerialPortBeta20120106.zip’ and ‘SdFatBeta20120108.zip’ to Arduino’s “libraries” directory (usually something like C:\arduino-1.0\libraries) and close and restart Arduino. To verify these are installed correctly, you should now see ‘SerialPort’ and ‘SdFat’ under the File->Examples menu.
|
||||
|
||||
For more information about installing Arduino libraries see the [SparkFun Learn tutorial](https://learn.sparkfun.com/tutorials/installing-an-arduino-library).
