USBStickLogger - Log serial data to an USB thumb drive
Web address : https://www.fischl.de/usbsticklogger/
With this circuit you can log serial (UART) data to an USB thumb drive and record data over a long period without the need of a PC. Simply connect your system to the logger and plug in an USB keydrive. All incoming data is logged to a file on the memory stick.
Features
No smd components are needed.
Firmware is open source.
Single power supply voltage: 5V (about 80mA).
Connection to your circuit with only three lines: +5V, GND, uC-Tx.
UART baudrate can be adjusted with a configuration file on the USB keydrive.
Usage
Connection
USBStickLogger has two connectors: the USB connector for the memory stick and a pin header socket for interfacing the UART and power supply:

2 GND
3 [uc-Rx/Logger-Tx]
4 GND

6 GND
7
8 GND
9 uc-Tx/Logger-Rx
10 GND
Configuration
Default setting for the UART is: 9600 baud, 1 start bit, 1 stop bit, no parity. You can configure this paramter by placing the file "CONFIG.TXT" to the USB thumb drive. Currently only the baudrate can be configured. Example:
COM_BAUDRATE: 115200
Logging
Once the device is connected and correctly configured, all incoming characters on the serial interface are written to the file "LOGGING.TXT" on the USB key drive.
Firmware
usbsticklogger_firmware_v1.2.tar.gz (2011-08-06)
Steps to compile the firmware:
Install the MAL Microchip Application Library (USB framework). Tested with v2010-10-19.
Unpack usbsticklogger*.tar.gz into a subfolder to the Microchip library folder.
e.g. C:\Microchip Solutions v2010-10-19\usbsticklogger\usbsticklogger_firmware_v1.2\
Open the Project with MPLAB IDE 8*. Tested with v8.63.
Compile with MPLAB C30. Tested with v3.24.
