Bus Pirate Preorders Open

Update, Saturday July 4th, 2009: All preorders are closed.

We’re excited to announce our partnership with the folks at Seeed Studio (home of the excellent Seeeduino) to put the Bus Pirate v2go into production! The preorder period ends July 3rd. The price is $30 including worldwide shipping. The board pictured above is a hand soldered prototype, but the ones sold by Seeed are completely factory assembled.

This is the first officially produced piece of Hack a Day hardware. Depending on its success, we’ll be able to put many future designs into production. Read more about the Bus Pirate in our latest How-to. Thank you for your support!

***Update, Monday June 29, 2009: Wow, your support has been overwhelming! Thank you! There have been more orders for the Bus Pirate than we ever imagined. As of this update, there’s a few (12) Bus Pirates left in the Seeed preorder. After that, we’ve exhausted the supply of PIC24FJ64GA002s available in Shenzhen. If you’ve already placed your order nothing changes, the manufacturing process has already begun and your Bus Pirate will ship ASAP.

After the first preorder is filled, Seeed will start a new preorder. The second preorder will be delayed until more PIC24FJ64GA002s are delivered, about 4 to 6 weeks. This order should ship about 6 to 8 weeks after July 3, 2009, but we’ll try our best to get it out sooner. Thank you again for your support!

How-to: The Bus Pirate V2 With USB

Update, Saturday July 4th, 2009: All preorders are closed.

The Bus Pirate is a universal serial interface tool, we use it to test new chips without writing any code. It currently supports most serial protocols, including 1-Wire, I2C, SPI, JTAG, asynchronous serial, MIDI, and more. We added some other features we frequently need, like pulse-width modulation, frequency measurement, voltage measurement, bus sniffers, pull-up resistors, and switchable 3.3volt and 5volt power supplies.

The new v2 family adds USB power and connectivity to the best Bus Pirate design yet. We also reduced the part count and cost wherever possible. If you want to get your hands on some Bus Pirate USB goodness, Seeed Studio has assembled hardware for $30 (including worldwide shipping).

Read about the new design after the break.

Bus Pirate Firmware Update V0g

June 25, 2009 by Ian 10 Comments

buspiratefirmwarev0g

Firmware v0g for all Bus Pirate revisions is now available. Updates in this release include a bootloader, frequency generator/pulse-width modulator, SPI bus sniffer, MIDI library, configuration reports, improved user interface, and bug fixes. v0g is also the first firmware to fully support the v2 hardware branch.

We’re really proud of this release as it brings a much more consistent structure to the internal operation of the Bus Pirate. It lays the foundation for future CAN, LIN, and OBDII libraries, and it supports localization and translations. Install and upgrade instructions are included with the firmware. Report bugs on the project issue tracker.

We document the new features after the break.

Bounty On Bus Pirate Features, Get A Free V2 PCB

March 25, 2009 by Ian 21 Comments

We’re putting a bounty on two high-priority Bus Pirate features. You can get a free PCB for the upcoming Bus Pirate V2 by writing a bit of code. Hack a Day has a varied and talented group of readers, and we know someone out there has the experience to make these changes with minimal difficulty.

The latest code integrates the PIC24F bootloader for easy updates without a programmer. We’d like to add a protocol snooper, but that requires interrupts. With the bootloader, however, interrupts are relocated and we’ve yet to fully grasp how that works. We’ll send a PCB and PIC 24F to the first person who modifies the code to demonstrate UART, SPI, or change notification interrupts with the boot loader. Microchip’s 24F bootloader app note is available here. Complete.

The current frequency measurement feature is a hack that uses a counter and a timer. Be the first to implement the input capture peripheral instead, and get a free PCB. See the function bpFreq(void) in base.c. Complete.

The latest Bus Pirate code and compiled firmware can be checked-out from Google Code SVN. Submit your code via the comments below or buspirate@hackaday.com.

UPDATE: Both issues were resolved. Thanks for your suggestions.

How-to: Bus Pirate V1, Improved Universal Serial Interface

January 22, 2009 by Ian 65 Comments

We use the Bus Pirate to interface a new chip without writing code or designing a PCB. Based on your feedback, and our experience using the original Bus Pirate to demonstrate various parts, we updated the design with new features and cheaper components.

There’s also a firmware update for both Bus Pirate hardware versions, with bug fixes, and a PC AT keyboard decoder. Check out the new Hack a Day Bus Pirate page, and browse the Bus Pirate source code in our Google code SVN repository.

We cover the design updates and interface a digital to analog converter below.

Bus Pirate Firmware Update (v.0c), JTAG And More

Download: buspirate.v0c.zip

A few weeks ago we wrote about our Bus Pirate universal serial interface tool. We used the recent holiday to add some new features, like a JTAG programmer, macros, frequency measurement, and more. A major code reorganization makes everything easier to read and update.

Check out the a demonstration of the new features below. We’re compiling a roadmap and wish list, so share your ideas in the comments. You can also see how we used the Bus Pirate to read a smart card and test-drive an I2C crystal oscillator.

How-to: The Bus Pirate, Universal Serial Interface

November 19, 2008 by Ian 60 Comments

UPDATE: New firmware with JTAG and more

We’re always excited to get a new chip or SIM card to interface, but our enthusiasm is often dampened by the prototyping process. Interfacing any chip usually means breadboarding a circuit, writing code, and hauling out the programmer; maybe even a prototyping PCB.

A few years ago we built the first ‘Bus Pirate’, a universal bus interface that talks to most chips from a PC serial terminal. Several standard serial protocols are supported at 3.3-5volts, including I2C, SPI, and asynchronous serial. Additional ‘raw’ 2- and 3- wire libraries can interface almost any proprietary serial protocols. 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.
