Second, there's a new "follow along” logic analyzer. A 74LVC8T245 buffer connects 8 of the new GPIOs to the 8 Bus Pirate IO pins. The follow along logic analyzer records what happens on the bus every time a command is sent. A live action logic analyzer..

Previous Bus Pirates can be used as a logic analyzer, but not when active in a mode. When the 1.2-5volt IO buffers are outputs the Bus Pirate can only see its own pin states. The actual bus may have a short or glitches that we can't see. The 8 pins are a second set of eyes..
