Support for the W1401 board with the following features:

  • serial interface through PD1/SWIM
  • 7S-LED through vectored I/O (auto-off w/ time delay while serial interface active)
  • board keys through vectored I/O
  • relay/red LED, and green LED through OUT!
  • buzzer with programmable pitch (BEEP_CSR HW-register)

Sensor input from the W1401 header can be read with 5 ADC! ADC@ (the analog input is surprisingly stable: there is just enough noise to get some extra resolution, but one still gets a stable readout down to the LSB without filtering).

Several issues fixed (e.g. #13 and #15).
