“ phatIO – a different way of interfacing a computer with the world.

When plugged into a computer’s USB port, phatIO (pronounced “fat-eye-oh”) appears as a USB filesystem/memory stick. You can control devices connected to phatIO by writing to files on that filesystem. Any computer that can write to a USB memory stick and any program/language that can write to a file can talk to phatIO.

phatIO significantly reduces the effort needed to control things with a computer – no drivers have to be installed or low level libraries used. Each of the 20 general purpose IO pins can be controlled by saving a “0” or “1” to their control file. Some features:

  • Small and compact (44 by 36mm), with a 2×14 IO socket. Great for embedding or use on a Breadboard
  • File based IO for each of the 20 Digital IO pins (12 are also ADC inputs and 5 PWM outputs). See an example 8 line shell script Larson Scanner
  • Customizable config driven drivers and device files to interface more complex devices behind a file. For example, a TWI interface LED display controlled by writing “1234” to a file on phatIO
  • Event and schedule driven system to execute actions when a digital or analogue condition occurs
  • Simulate typing on a USB keyboard with a few lines of config
  • Upgradable by dragging the new version to the phatIO filesystem“


Emulating USB Devices with Python

„Not long ago, I was giving a lecture to Sergey Bratus’s class at Dartmouth, where he asked me to teach the students about SPI, I2C, and the other bus protocols that are commonly found in embedded systems. When a student made the inevitable joke about Sergey’s Magic School Bus, my good neighbor’s eyes lit up and he exclaimed, „It’s not a bus; it’s a network!“

Our rough prototype was refined into a single board, which is documented as the Facedancer10 as part of the GoodFET project. The board consists of a GoodFET41 with the MAX3420 target onboard“
