最近找到个开源的编程器BPv3，支持类型不少，看着稀奇，收录了，以下是原文
Interfacing a new microchip can be a hassle. Breadboarding a circuit, writing code, hauling out the programmer, or maybe even prototyping a PCB. We never seem to get it right on the first try.
The ‘Bus Pirate’ is a universal bus interface that talks to most chips from a PC serial terminal, eliminating a ton of early prototyping effort when working with new or unknown chips. Many serial protocols are supported at 0-5.5volts, more can be added.
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
We added other stuff we need, like,
0-6volt measurement probe
1Hz-40MHz frequency measurement
1kHz - 4MHz pulse-width modulator, frequency generator
On-board multi-voltage pull-up resistors
On-board 3.3volt and 5volt power supplies with software reset
Since this has been such a useful tool for us, we cleaned up the code, documented the design, and released it here with specs, schematic, and source code.
