OpenLog v4 is refactored with better RAM utilization for better performance at higher record speeds (115200/57600). OpenLog v3 is stable, supports FAT32 cards up to 64GB and supports higher record speeds (115200/57600). OpenLog v2 is a bit buggy but supports FAT32 and SD cards up to 16GB. OpenLog v1 is stable but only supports FAT16 and up to 2GB. * **v1.0** Buggy initial release * **v1.1** Small changes to system settings and EEPROM storage. * **v1.2** Added wild card to listing and remove commands. Added read file command. * **v1.3** Added auto buffer record if unit sits idle for more than 5 seconds. * **v1.4** Increase buffer size to 900 bytes. Pinning down URU errors. * **v1.5** Lowered power consumption to ~2mA avg. Added 4800 and 19200 baud rates. * **v1.51** Added configurable escape character, and escape character amount. * **v1.6** Added ability to configure via config.txt file. * **v2.0** Massive overhaul. Ported to sdfatlib. Now supports FAT16/FAT32/SD/SDHC. * **v2.1** Power save not working. Fixed issue 35. Dropping characters at 57600bps. * **v2.11** Tested with 16GB microSD. Fixed issues 30 & 34. Re-enable power save. * **v2.2** Modified append_file() to use a single buffer. Increased HardwareSerial.cpp buffer to 512 bytes. * **v2.21** ringp fork brought in. rm dir, cd .., and wildcards now work! * **v2.3** Migrated to v10.10.10 of sdfatlib. Moved to inline RX interrupt and buffer. * **v2.4** Merged ringp updates. Commands cd, rm, ls work again! * **v2.41** Power loss bug fixed. Adding support for 38400bps for testing with SparkFum 9DOF IMU logging. * **v2.5** Added software reset command. Modified the read command to print extended ASCII characters. * **v2.51** Changed command prompt control to ignore \n for easier control from microcontroller. * **v3.0** Migration to Arduino v1.0 and better recording speed at 115200bps and 57600bps. * **v3.1** Better handling of recording during power loss. * **v3.2** Freed up RAM for larger RX ring buffer. Added support for wildcards and ability to ignore emergency override. * **v3.3** Added ability to ignore escape character checking and corrected incremental log naming. * **v4.0** Re-worked to be compatible with Arduino v1.6.x. Freed RAM to increase RX buffer size.
