Bus Pirate (Universal Serial Interface-I2C, SPI, JTAG, UART)
The Bus Prate is a great hardware tool for serious electronics practice. It has so many applications ranging from communication between a PC and any embedded device over most standard serial protocols, which include I2C, SPI, UART, JTAG, 1-Wire, HD44780 LCD and MIDI- all at voltages from 0-5.5VDC.
In addition to all the above data conversions, Bus Pirate also can be used as frequency analyzers oscilloscope, logic analyzer, flash chip programming, AVR programming, FPGA and CPLD programming
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.
A big bonus is the bootloader installed on the PIC, which allows you to easily update the firmware and change the functionality of the board.
