SOund MOdule 2 (SOMO-II) The SOMO-II (SOund MOdule 2) is a tiny Audio-Sound module that can play MP3 audio files stored on a micro-SD card (or USB 2.0 Flash drive with extra components), such as voice and music.

The SOMO-II features an on board 16bit MCU, specifically designed for hardware audio decoding.

The SOMO-II supports both FAT16 and FAT32 formatted micro-SD and USB Flash Drives (not on board, requires external components) up to 32Gb in size, and features a 24-bit DAC output with support for all MP3 bit rates (11172-3 & ISO13813-3 3 Layer Audio Decoding) with 8-Khz to 48Khz Sampling Rate.

Files can be stored in the root folder of the micro-SD or USB Flash drive, else in folders. It supports up to 99 folders and every folder can contain up to 255 songs.

Audio files can be easily loaded to the micro-SD card or USB Flash drive using a PC/Laptop, and inserted into the SOMO-II for playback.No external software is required.

The compact 16pin drop-in-module takes up very minimal board space and is ideal for any application that requires embedded audio.

The SOMO-II features an on board mono Amplifier capable of driving an 4ohm 3 Watt speaker directly. It also features stereo DAC output for connecting directly to headphones or into an external amplifier.

The module offers two modes of operation, SERIAL-MODE and the KEY-MODE.

The SERIAL-MODE provides a simple 2-wire Serial UART interface to any micro-controller via its TX and RX pins. Audio operations such as PLAY, PAUSE, STOP, NEXT, PREVIOUS and VOLUME control functions are all available to the host micro via simple serial commands, along with many more. SERIAL-MODE features a CRC check.

The KEY-MODE provides a stand-alone operation where a host micro is not required. It is possible to control the module with just 2 buttons, or an array of buttons can be added via various resistor values to get full control of the module without having to use an external processor.

With only 2 push buttons, a 3.3V to 5V battery and a speaker, an extremely compact and low component count MP3-Player like system can be implemented.

In short, the SOMO-II offers a very flexible, compact and low cost embedded audio solution for many applications

WORKSHOP4 IDE

Workshop4 is a comprehensive software IDE for Microsoft Windows that provides an integrated software development platform for all of the 4D family of processors and modules. The IDE combines the Editor, Compiler, Linker and Downloader to develop complete 4DGL application code.

All user application code is developed within the Workshop4 IDE.

DEVELOPMENT ENVIRONMENTS THAT SUITS ANY APPLICATION & USER LEVEL

Workshop4 includes four development environments for the user to choose based on application requirements or even user skill level.

Designer

  • Enables user to write 4DGL code to program the display module.
  • 4DGL syntax is similar to C: no need to learn a new language.
  • 4DGL is optimized for GOLDELOX, PICASO, PIXXI and DIABLO Controllers.

Visi

  • Aptly named, a visual programming experience as you develop the display.
  • Enables drag and drop of objects in a WYSIWYG editor.
  • Software generates 4DGL code for the graphics.

Visi-Genie

  • An advanced environment; no 4DGL coding Required.
  • Everything is automated.
  • Drag and drop objects on the display.
  • Code written automatically.

Serial

  • ransforms the module into a serial slave.
  • Control the module from any host microcontroller with a serial port.
  • All serial protocols and documentation are provided.

WORKSHOP4 PRO

Make complex widget design, simple.

Smart Widgets Editor is a powerful utility which enables the generation of Smart Widgets.

  • Users can create complex widgets with up to six layers, including the layer for the base image. The order of the layers can be arranged as desired.
  • Each layer can contain one or more images arranged in sequence that can be manipulated in a variety of ways. Image manipulation options include horizontal motion, vertical motion, and angular motion. Additionally, the transparency of a layer can be set.
  • Two or more layers can be linked to produce synchronized movements of images. This enables the generation of complex widgets with multiple moving parts. Clockwork feature is also supported. This enables users to quickly generate clock widgets.
  • Each layer can have a numeric part which can display numbers in various fonts and formats. Alternatively, the numeric part can be a fixed sequence of text.
  • The output frames can be utilized using any of the supported Workshop4 environments.

GENIE MAGIC

Genie Magic is an extension to ViSi-Genie, which is available in Workshop4 PRO. Genie Magic allows the User to add 4DGL code to various points in the ViSi-Genie backend code, which allows Users to take full advantage of the power of 4DGL, while retaining the speed and convenience of ViSi-Genie and its defined communication protocol.

Genie Magic allows you to enter 4DGL code in the form of Events, Code and Objects, along with various touch related additions too, giving you to the power to achieve advanced GUI’s in ViSi-Genie without having to write the full code yourself.

Genie Magic is fully supported by the genieArduino and geniePi libraries, making communication with an Arduino or Raspberry Pi host even more powerful.

When using Genie Magic in combination with the Smart Widget Editor, it is possible to use the Smart Widgets Editor tool and Smart Widgets to create other graphical user interface elements such as:

  • Dropdown Menu

  • Side Menu

  • ‘Carousel Slider’

  • List Box

  • Dock Menu

  • Quarter-Rotary Menu

  • Fading Slide-To-Unlock Button

  • Spectrum With Transparency

  • And Many Others

DOWNLOADS

Compatibility: Workshop4 is a Windows-only product. It is compatible with Windows 8 through to Windows 11.

Note some older OS such as ME, Vista, XP and 7 have not been tested for some time and are not supported by Microsoft anymore; however, they may still work.
Legacy support updates for the older OS may not be possible, depending on what issues are found. For best results, run a current Windows OS. It is possible to run Workshop4 under a VM on Linux or Mac. However, it is up to the User to set this up.
