Detailed Description

As such, the system architecture is kept simple, and the function of each device is kept as simple as possible to aid in learning. The basic MOST ToGo system contains 3 nodes: A simple audio source device (AuxIn), a simple audio sink device (Amp), and a controller device that has a simple user interface (HMI) The HMI is the network master, while the source and sink devices are network slave devices.

The default firmware creates a system which includes a master or controller device, a source device and an sink device. The source and sink devices are slave nodes in the system. The master controller device is connected to the simple HMI display and is referred to as the HMI_Master device in the system. The source device is meant to connect an analog source (MP3 player) to the MOST network and is called the MP3_AuxIn node. The sink device implements a MOST network sink which connects to headphones or powered speakers and is called the Main_Amp node. Additionally, the master device can also provide another analog source input (HMI_Aux In) and headphone output (HMI_Amp) so that the overall system has two sources and two sinks.

The kit is based on the OS81092 ePhy Evaluation Board. In addition to the major components, the board also has several user interface components which are listed below.

OS81092 ePhy Evaluation Board (B20003)

A complete MOST50 Network device, utilizing the Microchip OS81092 (INIC) device. An on-board PIC32MX795 External Host Controller (EHC) is available for development of custom application code or use of application code provided by Microchip. An integrated Microchip OS85650/2 (IOC) device provides I/O port expansion for additional application flexibility. The OS81092 ePhy Board also supports power management, controlled by the Microchip MPM85000 Power Manager Device (PwrMgr), a MOST specification compliant power management device.
