USB --- VCOM

Hi all,
I am using the LPC176. I am using an example project for Vcom using USB Device controller in 1769. By default it works at 9600 baud. But I don't understand how to change the baud rate - I want to use it at higher baud rate...

Any suggetion???

  • More details, please.

    Are you talking about PC side, or firmware?

    PC side:
    - What is your OS?
    - What is your application? (ex. RealTerm)
    - Or, are you coding a PC application? Then, what is the programming language?

    Firmware side:
    - What is the USB example, exactly?
    ex. C:\Keil\ARM\Boards\Keil\MCB1700\RL\USB\Device\CDC

    Anyway, the baudrate setting doesn't affect to USB transfer speed, at all ;-)

  • The baudrate setting of Virtual Comm lies in your firmware.

    For an example, with CDC class and appropriate subclass setting, the baudrate parameter (and number of data bits, stop bit, parity bit) could be configured by LINE CODING related callbacks.
