Adding USB Host capability to MSP430 using FTDI

Todd Anderson65442

All:

FTDI has a chip called the VNC2, which can be used to add USB host capability to a microprocessor.

Does anyone have experience they can share regarding adding the FTDI chip to an MSP430 as host?

For instance, the FTDI can be connected via SPI or UART. Is there a preferred connection?

Regards,

Todd Anderson

    I have been in communication with someone on the FTDI side of things, and here is his take:

    "Hello Todd, the more I think about this the more I think it is a GREAT example!

     The MSP430 Bootstrap loader is resident in all parts and is well documented. I remember seeing a PC ap from TI that was the Windows side of a loader. This would make life simpler since you basically need to port this ap to the V2 - should be straight forward since VOS has a similar programming model to the PC (ie an ap that calls driver APIs).

    On PowerOn the FTDI VNC2 could hold the MSP430 in reset, check if a flash drive was attached, then release MSP430 reset and use the Bootloader protocol if necessary. Then VNC2 could power down."

    Can I get the PC app code to then port to the VNC2?

    Regards,

    I found the PC app code - it is part of SLAU319A - Programming via BSL.
