Bounty on Bus Pirate features, get a free v2 PCB

bpv2

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: Web server on a business card (Part 2)

This mini web server is slightly smaller than a business card. There are a lot of tiny one-board servers out there, but this is probably the smallest you can etch and solder at home. Unlike many embedded web servers, files are stored on a PC-readable SD card, not in a difficult-to-write EEPROM. Read on for the web server design, or catch up on PIC 24F basics in the previous article: Web server on a business card (part 1).
