VMusic3 Signals and Configurations 3 3.1 VMusic3 Pin-Out Figure 3.1 – VMusic3 Pin Out (in UART mode) The pin-out is illustrated in Figure 3.1. 3.2 VMusic3 Jumper Configuration The VMusic3 comes preloaded with the V2MSC firmware and the jumper is set to UART mode by default. Adjusting the jumpers accordingly configures the module to operate in SPI mode. The interface modes of the VMusic3 running on a V2MSC firmware are given in Table 3.1 UART/SPI Interface Mode Pull-Up UART Pull-Down SPI Table 3.1 – VMusic3 Jumper Box 3 Copyright © 2013 Future Technology Devices International Limited

VMusic2 and VMusic3 comparisons 4 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. 4 Copyright © 2013 Future Technology Devices International Limited

VMusic3 Version 1.0 Document Reference No.: FT_000738 Clearance No.: FTDI# 336 VMusic3 Application Example 5 VMusic3 can be used to play audio from a flash disk. An example is given where a PIC is used to send commands to the VMusic3 select playing option such as play, pause and skip. It is also possible to control the VMusic3 from a PC using a TTL-232R-3V3-2mm and a terminal. See Vinculum Firmware User Manual for details on the control commands. 5.1 UART Interface to PIC Example Figure 5.1 – MP3 playback using VMusic3 controlled by a PIC MCU A VMusic2 compatible example is given in Figure 5.1. This example shows a VMusic3 interfacing with an external PIC MCU and supporting components. In this example four push buttons are used to control play / pause, stop, skip forward / volume up and skip back / volume down of the MP3 player.

VMusic3 Version 1.0 Document Reference No.: FT_000738 Clearance No.: FTDI# 336 VMusic3 Electrical Details 7 7.1 SPI Interface Timing The following timing diagrams are for the VNC1L Legacy Interface mode of SPI slave. SCLK SS# MOSI MISO Figure 7.1 – SPI To start the data transfer process SS# needs to be set high, and remain high for the entire read cycle. Once the read cycle completes SS# needs to be set low for at least one clock cycle to allow another data transfer cycle to occur. The first bit of MOSI is the R/W bit, receiving a logic high for this bit allows data to be read from the VMusic3.The second bit is the address bit, ADD, this bit is used to select reading data from the data register when set to logic high, or from the status register when set to logic low. During an SPI Read cycle a package of data is transmitted from the VMusic3 on the MISO line from the time of the first clock cycle after the SPI ADD bit, with the MSB transmitted first. After the data has been transferred the status of MISO can be checked to determine if the data read is new data that has not been read before, which is indicated by a transmitted logic low. Otherwise if old data is being transmitted, which is indicated by a transmitted logic high, the read cycle needs to be repeated to get new data. SCLK SS# MOSI MISO Figure 7.2 – VMusic3 SPI Waveforms To start the data transfer process SPI SS# needs to be set high, and remain high for the entire write cycle. Once the write cycle SPI completes SS# needs to be set low for at least one clock cycle to allow another data transfer cycle to occur. The first bit of MOSI is the R/W bit, receiving a logic low for this bit allows data to be written to the VMusic3. 7 Copyright © 2013 Future Technology Devices International Limited

VMusic3 Version 1.0 Document Reference No.: FT_000738 Clearance No.: FTDI# 336 The second bit is the address bit, ADD, this bit is used to select a data write to the data register when set to logic high, and to the status register when set to logic low. During an SPI Write cycle a package of data is transmitted to the VMusic3 on the MOSI line from the first clock cycle after the SPI ADD bit, with the MSB transmitted first. After the data has been transferred the status of MISO can be checked to determine if the data written has been accepted. If a logic low is given for the status bit, it can be determined from this that the data write was successful. If logic high is given for the status bit, the internal buffer of the device receiving data is full, and the same write cycle should be repeated.
