SMARTWAV 2 Serial Mode SmartWAV 2 processor internally is a sophisticated multi-task system, it processes individual .wav tracks mounted on each of the 14 channels, mixing those with a master sample rate and a master gain control, this process is automatically. The master sample rate is how the processor outputs audio samples; this parameter is global for all 14 channels. The master gain control (master mixer volume) is a global parameter that affects all the 14 channels.
PAGE 12
SMARTWAV 2 Serial Mode Point A and Point B are markers that the processor handles for each channel for rewind, loop points and other functions. Each time a track is mounted, the points A and B are set at their defaults: A-Start of track and B-End of track (blue color). User can later set and re-define those A and B points (green color) by the respective command.
PAGE 13
SMARTWAV 2 Serial Mode 3- Operation Modes: The module offers 8(eight) modes of operation; selection between modes is by setting the external pins M0, M1 and M2, this document covers only the Polyphonic Slave Standard Serial Mode 0, for more operation modes please refer to the document SmartWAV2Datasheet.pdf. 3.
PAGE 15
SMARTWAV 2 Serial Mode 5- Polyphonic Slave Serial Mode 0 - Standard Serial: 5.1- Master-Slave Host Interface: SmartWAV 2 in this mode acts as a slave peripheral device, providing a bidirectional serial interface to a master host controller via its UART(Universal Asynchronous Receiver - Transmitter), the required pins of Standard Serial Mode 0 are labeled with a white rectangle.
PAGE 16
SMARTWAV 2 Serial Mode 5.3- Power-up, Reset and Serial Setup: When the SmartWAV 2 device comes out of a power up or reset, a 50ms delay before sending any command must be met, this time let the processor to configure its internal state machines, do not attempt to communicate with the module before this period. Any command could be sent after this time. The processor is configured to work at a standard default baud rate of 57600bps.
PAGE 17
SMARTWAV 2 Serial Mode 5 GROUND POWER Supply ground, be sure to have a wellgrounded connection to avoid noise over the audio outputs. 6 3.3V POWER Main supply voltage: 2.7v-3.5v. Be sure to use a 10uF and 100nF coupling capacitors to GND as close as possible to avoid noise over the audio outputs. 7 Rx - V+ INPUT Digital input pin RX (asynchronous serial receiver input pin). Internally pulled-up to 3.3V via a 40K resistor. 5V tolerant input.

SMARTWAV 2 Serial Mode 10-MicroSD File/Folder Organization - Standard Serial Mode0: The SmartWAV 2 is capable of managing and folders in this mode, so a complete library organized by artist/ album/ genre/ year/ etc. could be done inside the micro SD card. Also the processor could access nested folders for example: “D:/rock/punk/oldies/song.wav”. In Stand-Alone Modes, the SmartWAV 2 only recognize .wav files stored in the root path of the microSD card, all .wav files must be placed in this path.

SMARTWAV 2 Serial Mode 11- Formatting MicroSD Card: It is recommended but not strictly necessarily to format the micro SD card for first use, in this section a format to new micro SD card to FAT format is explained. A.- Open a new windows explorer right click on the microSD card and a menu appears, select the “FORMAT…” and click on it. (Note that formatting a micro SD card will erase all the contents of it).
PAGE 114
SMARTWAV 2 Serial Mode B.- A new window will pop-up, chose FAT/FAT32(default) on the File System menu, and click start. C.- Click OK on the new window and wait to the PC to perform the format.

SMARTWAV 2 Serial Mode 12- Development Software & Hardware Tools In order to make easier the learning about how to communicate with the SmartWAV 2, free software could be downloaded and used in any PC. This software simulates almost all of the functions of the processor in Standard Serial Mode 0, this is achieved by connecting the hardware tool USB-UART SX Bridge to the SmartWAV 2 enabling real time audio processing, the required pins of Standard Serial Mode 0 are labeled with a white rectangle.
