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. 'new' will create a new file. 'md' makes a directory. '?' brings up the list of commands. OpenLog doesn't do a lot, but it does log serial streams extremely well.
Features:
Log to low-cost microSD FAT16/32 cards up to 16GB
Simple command interface
Edit config.txt file from a computer to change baud rate and other system settings
Three modes:
NewLog creates a new log every power up and immediately starts logging
SeqLog appends a file called "SeqLog.txt" at every power up and immediately starts logging
Command mode starts OpenLog at a command prompt at power up
Configurable baud rates (2400 to 115200bps)
Configure unit through config file or the menu system
Power, ground, and RX-I are the minimum connections
Reprogrammable ATmega328 using the Arduino IDE
Two LEDs indicate writing status
Input voltage from 3.3V to 12V
2mA idle, 6mA at maximum recording rate
Dimensions: 0.16 x 0.6 x 0.75" (4 x 15 x 19mm)
