FTDI Buffer Fix on Linux

Summary

This tutorial has been verified to work with the following Linux versions:

  • Ubuntu 18.04

Step 1: Make sure FTDI driver is installed

Make sure that the FTDI driver has been installed and you can connect to the Cyton.

Step 2: Open latency_timer file

Using file manager, open the latency_timer file. Found at:

/sys/bus/usb-serial/devices/ttyUSB0/latency_timer

where ttyUSB0 is the serial port name for the OpenBCI dongle.

Step 2: Change 16 to 1

The latency_timer should contain 16 by default. Change this to 1, and you're done!

Step 3: Test OpenBCI GUI or BrainFlow

Run the OpenBCI GUI or a BrainFlow binding, and you should see smoother data.
