The RPICT USB Adaptor aim to interface any RPICT series board with a USB port. This can equally be used on a computer or a Raspberrypi.

==Usage on a computer==

Data output is read on the serial port. The serial port will depend on your operating system.<br>
This will be /dev/ttyUSB0 on linux and a com port on windows.

Baud rate is 38400.

A good cross platform tool for reading serial ports is [https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html putty].

Or you can use [https://github.com/hyOzd/serialplot SerialPlot] which is good for plotting data in realtime. Use data format as ASCII and Column delimiter as space.

Note that a Raspberrypi is needed to configure the RPICT board.

==Usage on a Raspberry pi==

As an alternative to stack the RPICT on the Raspberry it is possible to use this USB adaptor to connect the RPICT to the USB port of the Raspberry. This can be a good way to free up the GPIO ports.

The configuration tool lcl-rpict-config can be used but in this case requires the serial port to be informed.

An example for reading the configuration
 lcl-rpict-config.py -p /dev/ttyUSB0

An example for writing a configuration file
 lcl-rpict-config.py -p /dev/ttyUSB0 -w myfile.conf

You should read the data stream with the commands below.
 stty -echo -F /dev/ttyUSB0 raw speed 38400
 cat /dev/ttyUSB0
