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&nbsp;communicate&nbsp;between host-PC and the LPC54618 as a COM Port device.&nbsp;</P><P></P><P>Thank you,</P><P></P><P>Evan</P></BODY></HTML> Fri, 28 Feb 2020 16:06:39 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-USB-CDC-Flow-Control/m-p/1031261#M40143 evan_ohlsen 2020-02-28T16:06:39Z Re: LPC546xx USB CDC Flow Control https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-USB-CDC-Flow-Control/m-p/1031262#M40144 <HTML><HEAD></HEAD><BODY><P>Hi Evan</P><P><SPAN style="color: #333333;">you can change whether DTE is present or not in the the Control Signal Bitmap Values.</SPAN></P><P><SPAN style="color: #333333;">&nbsp;flow control can be changed with <STRONG>USB_DeviceCdcEvent SetControlLineState</STRONG><STRONG style="color: #51626f; background-color: #ffffff; border: 0px; font-weight: bold;">.</STRONG></SPAN></P><P></P><P><SPAN style="color: #333333;">Have a nice day,</SPAN></P><P><SPAN style="color: #333333;">Jun Zhang</SPAN></P><P><SPAN style="font-size: 10.5pt;">&nbsp;</SPAN></P></BODY></HTML> Mon, 02 Mar 2020 05:11:36 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-USB-CDC-Flow-Control/m-p/1031262#M40144 ZhangJennie 2020-03-02T05:11:36Z
