SparkFun:<\/strong> DEV-09530<\/p>\n

Description:<\/strong> The SparkFun OpenLog is an open source data logger. Simple to use, simple to change. We wanted to create a serial logger that just worked. Power up this device and it will start logging any received serial data at 9600bps. Sending Ctrl+z three times will drop out of logging and in to command mode. \u2018new\u2019 will create a new file. \u2018md\u2019 makes a directory. \u2018?\u2019 brings up the list of commands. OpenLog doesn\u2019t do a lot, but it does log serial streams extremely well.<\/p>\n

Example:<\/strong><\/p>\n

\r\n >new testfile.txt  \r\n >append testfile.txt  \r\n <(send large amounts of text followed by three ctrl+z characters)\r\n<\/pre>\n
That\u2019s really it! OpenLog firmware is open source and is based on Bill Greiman\u2019s sdfatlib. OpenLog currently supports FAT16 and FAT32 microSD cards (we\u2019ve tested up to 64GB!).<\/p>\n
All the design files (schematic, PCB layout, firmware) are open source released under the CC-SA v3 license and are available through GitHub.<\/p>\n
Note:<\/strong> New firmware is available which allows the OpenLog to be used in Arduino 1.0 and also allows for higher baud rates. Check the links below for more information.<\/p>\n
