MSP430 USB vendor specific class

Sharadanand Karanjkar

Hello All,

In one of our project we need a vendor specific USB device class. However we searched in MSP430 community and various documentation sources including following forum-

http://e2e.ti.com/support/microcontrollers/msp430/f/166/p/117537/429268.aspx#429268

But none of the information has been useful for our cause.

Can anyone help us out?

    Hi Sharadanand,

    While we do provide the APIs out-of-box for HID, CDC, MSC and some others, it is possible to customize and create a vendor specific class. All the documentation for the USB module as well as the source for our existing USB stack are available. However, beyond these default class APIs we do not have any additional abstraction layers for the USB.

    It is definitely a custom solution and a custom effort that would depend on what your vendor-specific class is doing. Since this is by definition custom, we don't really have an example for this - every case will be different based on vendor-specific requirements. Keep in mind that the defined classes are provided in order to make development with MSP430 USB easy, requiring as little actual USB development as necessary on the part of the user.

    If you need to create this vendor-specific class it is something you will likely have to implement on your own by modifying the USB provided USB stack, or by hiring a third party with USB software experience to create your custom stack to your specifications. Because it is custom class and particular to your use-case it is not something we already have provided or ready-made though.

    Regards,

    Katie
