Equipment/Bus Pirate

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.
