VDIP (USB module)

The VDIP module[33] uses the FTDI[34] module to provide a serial to USB interface. Hence gives the ease of program development for a serial interface while providing the convenience of USB support. This module is connected to the Gumstix via on of its serial interfaces (FFUART) which is shared among this and the console access through a PC. The VDIP module has its own instruction set which are quite primitive but nevertheless easy to use and more than sufficient for this application.

More details on how the sharing of the serial port functions is available in the later sections.

Figure 3.12 shows the VDIP module on its own.
