LPC546xx USB CDC Flow Control

[evan_ohlsen]

I have been testing out the LPCXpresso 54618 dev board and trying to implement a serial com port using the onboard high-speed USB controller (USB1). The USB SDK available on NXPs website includes a virtual com port example project called "dev_cdc_vcom" which echoes the characters sent by the host PC through a virtual COM port, but does not seem to implement flow control. Is there a way to implement flow control between the Onboard USB1 device controller and the host-PC? I would like to be able to use the USB1 controller to communicate between host-PC and the LPC54618 as a COM Port device. 

Thank you,

Evan

Hi Evan

you can change whether DTE is present or not in the the Control Signal Bitmap Values.

 flow control can be changed with USB_DeviceCdcEvent SetControlLineState.

Have a nice day,
