The Bus Pirate v3.6a, created by Ian Lesnet, is a troubleshooting tool that communicates between a PC and any embedded device over 1-wire, 2-wire, 3-wire, UART, I2C, SPI, and HD44780 LCD protocols - all at voltages from 0-5.5VDC.
Working with the Bus Pirate is simple and effective - type commands into a terminal on your computer, those commands are interpreted by the Bus Pirate and sent via the proper protocol. The Pirate will also interpret data sent from your embedded device back to your computer terminal.
Bus Pirate Features: 5.5V tolerant pins. 6V measurement probe. 1Hz - 40MHz frequency measurement. 1kHz - 4MHz pulse-width modulator, frequency generator. On-board multi-voltage pull-up resistors.
Also Features: On-board 3.3volt and 5volt power supplies with software reset. Macros for common operations. Bus traffic sniffers (SPI, I2C) A bootloader for easy firmware updates. Transparent USB->serial mode. 10Hz - 1MHz low-speed logic analyzer.
The main components of the Bus Pirate are the PIC24FJ64 processor and a FT232RL USB-to-Serial chip. A Mini-B USB connector that has also been populated on the board, provides the power to the Bus Pirate and allows you to interact with via your PC.
