Bus Pirate

Description

The Bus Pirate is a low-level interface to:

  • 1-Wire
  • UART
  • I2C
  • SPI
  • JTAG
  • raw 2-wire
  • raw 3-wire
  • PC keyboard
  • HD44780 LCDs
  • MIDI

It includes an ADC and can bit bash these protocols at the wire level. It can also be put into UART bridge mode, acting as a simple serial port.

How to get a shell anything UART

Follow this step to get a shell using the bus pirate to you UART devices.

  • First find the UART baud rate for the device. You can generally find this information from the constructors manual or using an oscilloscope.Note it on a piece of paper.
  • Find the connecting plug for it. Need some magic here. It mostly trying to find the GND first using tester and trying to find the voltage pin and data pin.
  • Connect you bus pirate to your device.
  • Find the new device using 'ls /dev/tty*'
  • Start a shell. Either trough minicom or screen.
  • m ( for mode)
  • 3 (for selecting the UART but you can select another mode if you need another protocol)
  • select your baud rate ( most common baud rate are 9600 or 115200)
  • default work in most of the case to get your shell on any devices 8
  • select stop bits is 1 most of the case
  • enjoy your shell.
