Bus Pirate firmware v3.5 is available for download. Update using the normal firmware upgrade procedure. This release does not reach into the upper memory page, so there shouldn’t be any upgrade issues. Changes include:

  • All bitbang libraries updated to include 100kHz and 400kHz speeds (I2C, raw2wire, raw3wire).
  • Updated self-test, includes over voltage check.
  • Transparent UART bridge macro with hardware flow control pass-through (v2go/v3 only).
  • Removed experimental hardware I2C mode.
  • User interface touch up.
  • Bug fixes here and there.

Since release v3.1 the Bus Pirate v2go and v3 share the same firmware. Upgrade v2go with the firmware for v3.
