VNC2 firmware model has evolved considerably since VINC1L. For reasons of code maintainability,
performance, stability and ease of use from the point of view of the customer, VNC2 has a modular
firmware model.
VNC2 firmware can be separated into 4 categories:
8.1 RTOS
The VNC2 RTOS (VOS) is a pre-emptive priority-based multi-tasking operating system. VOS has been
developed by FTDI and is available to customers for use in their own VNC2 based systems free of charge.
VOS is supplied as linkable object files.
A full explanation and how to use VOS is available in a separate application note which can be
downloaded from the
8.2 Device drivers
To facilitate communication between user applications and the VNC2 hardware peripherals FTDI provides
device drivers which operate with VOS. In addition to the hardware device drivers, FTDI provides
function drivers (available from the
functionality for a specific purpose. For example, drivers for standard USB device classes may be created
which build upon the USB host hardware driver to implement a BOMS class, CDC, printer class or even a
specific vendor class device driver.
