USB succeeding data transmission interface?

BertrandR — Sat, 07 Jan 2023 11:06:25 GMT

Hello,

Newby with LPC, I am trying to setup VCOM communication on my custom board with a LCP55S16

I am using "peripherals tool" to try to set up with preset but I have a field in error and I don't understand at all what should be the value. I try from 0 to 255 without any result. Error should be some where else.

Thank you for your help

Bertrand

Hi,

I think you can download SDK package from the link

https://www.nxp.com/design/software/development-software/mcuxpresso-software-and-tools-/mcuxpresso-software-development-kit-sdk:MCUXpresso-SDK

There is usb_device_cdc_vcom example, you can refer to the example

Hope it can help you

Hi,

You need to setup two interfaces, CIC VCOM and DIC VCOM. These two interfaces map to three endpoints (Interrupt In, Bulk In and Bulk Out).
