Bus Pirate Kit

The Bus Pirate is a universal electronic open hardware tool to program and interface with communication buses and program various chips, such as AVRs from Atmel and PICs from Microchip Technology. A primary usage case for this device as intended by the designers is to “Eliminate a ton of early prototyping effort with new or unknown chips.”Using a Bus Pirate, developers can use a serial terminal to interface with devices over a variety of hardware protocols, such as SPI and 1-Wire.

Support for many serial protocols with line levels of 0 – 5.5 volts:

•     1-Wire
•     I²C
•     SPI
•     JTAG
•     Asynchronous serial
•     MIDI
•     PC keyboard
•     HD44780 LCD
•     2- and 3-wire libraries with bitwise pin control
•     Scriptable binary bitbang, 1-Wire, I2C, SPI, and UART modes

Other capabilities:

•     0 – 6 volt measurement probe
•     1 Hz – 40 MHz frequency measurement
•     1 kHz – 4 MHz pulse-width modulator, frequency generator
•     On-board multi-voltage pull-up resistors
•     On-board 3.3 volt and 5 volt power supplies with software reset
•     Macros for common operations
•     Bus traffic sniffers (SPI, I²C)
•     A bootloader for easy firmware updates
•     Transparent USB -> serial mode
•     10 Hz – 1 MHz SUMP compatible low-speed logic analyzer
•     AVR STK500 v2 programmer clone
•     Supported in AVRDude programmer
•     Scriptable from Perl, Python, etc.
