VMusic2 and VMusic3 comparisons

The VMusic3 is a drop in replacement for the VMusic2 for the majority of VMusic2 applications. VMusic3

uses firmware called V2MSC which is similar to V2DAP (used in VDRIVE3) with an additional module for

controlling MP3 playback. However for a small number of applications that use SPI, differences exists

between VMUSIC firmware and V2MSC firmware which would require some changes to be made to the

application software. For further details on this discrepancy please see AN_176 - Vinculum Comparison of

VDAP and V2DAP.

Additional features of the VMusic3:



Vinculum-II can be configured by a user defined firmware



VMusic3 has an SPI master interface available (not enabled in V2MSC firmware).



VMusic3’s SPI interface can be clocked up to 24MHz



VMusic3 can be programmed using the debugger-module port in addition to programming using

the UART interface port.



VMusic3 can utilise many of the Vinculum-II sample firmware available on the FTDI website.
