BPIO2 binary mode

Not sure if it is best to resurrect this old thread, or start a new one.

Currently working through BPIO2 updates for:

  • UART (firmware and python lib support complete)
  • LED mode (firmware and python lib testing now)
  • 3Wire (written, not tested)

The major change is the addition of a is_async to the Data Response table. This indicates packets that arrive async from any deliberate data request. For example UART, HDUART, and INFRARED.
