I was testing with the dev_cdc_vcom_bm example from MCUXpresso SDK, and an LPCXpresso54628 eval board.
I can configure the USB device worked in high-speed mode, and it's about 4MB/s when sending data to PC.
I want to know what the highest transfer rate can be, could it reach to 40MB/s as mentioned here https://community.nxp.com/message/760578
What do you mean by virtual com device?
I am running the dev_cdc_vcom_bm example from SDK, the USB1 will be recognized as a virtual com port from the PC, LPC board send data through USB1 to PC, and PC read data through the virtual com port, the speed can reach to about 4MB/s.
My question is what's the highest speed can reach? some people said that could reach to 40MB/s, and that sounds reasonable since the high-speed USB can reach to a 480Mb/s about 60MB/s.
Hi will hunt
According to LPC546xx datasheet, USB1 speed can reach 480Mbit/s.
Have a great day,
Jun Zhang
