Datasheet

7- Polyphonic Slave Serial Mode 4 - MIDI Serial:

7.1- MIDI Host Interface:

SmartWAV 2 in this mode acts as a slave peripheral device, providing

a unidirectional serial interface to a host MIDI controller via its

UART(Universal Asynchronous Receiver).

Any MIDI compliant device can communicate with SmartWAV 2 using

standard MIDI commands, note on, note off, program change, etc.

(Refer to document SmartWAV2-MIDI.pdf). Midi channel selection is

via the I0-I3 input pins, this allow a logical binary selection of channel

0(0000b) to 15(1111b), however inside the processor this is handled as

channel: n+1, resulting in a 1 to 16 channel selection. The STP pin acts

as a midi omni-channel enable/disable pin, when enabled it overrides

the I0-I3 pins channel selection.

The serial protocol over MIDI is universal:

Serial Data Format: 8 Bits, No Parity, 1 Stop Bit.

BaudRate: 31250 bps(default).

Serial data is true and not inverted.
