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.
Reference
Our connector
brown - GND red - +3.3 orange - +5 yellow - ADC green - VPU blue - AUX purple - CLK grey - MOSI white - CS black - MISO
NB This order depends on attachment as connector is symmetrical and may be inverted.
Sparkfun Connectors
I have noticed that the sparkfun connector and buspirate uses the following mappings
black – gnd white – 3.3V grey – 5V purple – ADC blue – VExtern green – aux1 yellow – clk orange – MOSI red – CS brown – MISO

Information about the schematics to use with any of the supported protocols can be found here [1]
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.
Real life example
As it happened at the LHS, the bus pirate interacting with a Hitachi HM55B compass module:
