The following commands will help you read, write, and delete files, as well as change the settings of the OpenLog. You can interface with the OpenLog via a serial terminal. This sketch is recommended for experienced users but is also the best option for the highest speed logging. OpenLog_Minimal - The baud rate must be set in code and uploaded.This is a good option for high-speed logging. OpenLog_Light - This version of the sketch removes the menu and command mode, allowing the receive buffer to be increased.Sending the ? command will show the firmware version loaded onto a unit. OpenLog - This firmware ships by default on the OpenLog.There are three included sketches you can use on the OpenLog, depending on your particular application. On power up, you will see either 12> or 12 indicates OpenLog is ready to receive commands. You can now open up a serial monitor and interact with the OpenLog. That's it! Your OpenLog is now programmed with new firmware. Open the OpenLog sketch you would like to upload under Tools>Board menu, select the "Arduino/Genuino Uno", and select the proper COM port for your FTDI board under Tools>Port. Please double check the example circuit if you are not sure how to do this properly. If you haven't yet, connect your OpenLog to the computer via an FTDI board. Save the file, and open up the Arduino IDE. Change BUFFERED_TX to 0 and ENABLE_RX_ERROR_CHECKING to 0. Next, to take advantage of the modified libraries, modify the SerialPort.h file found in \Arduino\Libraries\SerialPort directory. GitHub: OpenLog > Firmware > OpenLog_Firmware.The SdFatLib and Serial Port libraries are not visible in the Arduino board manager so you will need to manually install the library. Looking for the Latest Versions? If you would prefer the most up-to-date versions of the libraries and firmware, you can download them directly from the GitHub repositories linked below.
