Hello,
V2DIP2 is supplied with V2DAP firmware pre-programmed, but please check you have the latest version.
The latest version is supplied with the
Vinculum-II Tools at the following location on the PC:
C:\Users\
Username\Documents\FTDI\Firmware\Samples\V2.0.2-SP2\VNC1L\V2DAP
Please refer to the
Vinculum Firmware User Manual for usage.
Also see
AN_176 - Vinculum Comparison of VDAP and V2DAP, as V2DAP is a port of VDAP.
Also note that on the UART side you will also require to connect the flow control signals (CTS/RTS) and this should be set by the UART application.
You can only host 2 x FT232R which will allow you to read from either of them and use one of them at a time in data mode.
It will never bridge between them though.
The VNC2 is quite a mature product.
Hosting FT232 devices with these older Vinculum/Vinculum-II products can be unreliable.
It takes a lot of the MCUs resources to run the FT232 device code so there can be performance issues.
I wouldn’t recommend using these products for this application.
The latest MCU
FT90x has similar features to VNC2 and is actively supported from R&D, so you might want to consider this product.
Take a look at
FT90x UART to FT232 Host Bridge, there is already a software example which can host FTDI devices.
A video has been created which demonstrates this:
https://youtu.be/_vwOKFaOcJIThere are significant benefits of FT90x over VNC2:
-Eclipse based IDE
-Source code for API drivers is provided
-Significant performance improvement
-Firmware updates over USB DFU
-Improved documentation and examples
We provide a free
FT9xx Toolchain and
FT9xx Development Modules.
