The question was abourt USB-UARTs (CDC ports), not about physical UARTS.
I would guess that USB would support having multiple virtual COM ports over a single USB connection. For example the FT2232 supports this IIRC. But I would also guess that the default windows driver cannot handle this...
Also, the USBUART component cannot handle this AFAIK, you would need to roll your own USB device driver on the PSoC side...
What is your use case here? Is there a reason not to handle multiple transfers of a single COM port? (I think the useable bandwidth would also be reduced in this scenario).
Hi Hli. thanks for your reply and corrections. regards, jesus
Hello hli, thanks for you reply......there is no particular reason for me not to use a single port for multiple transfers..
Its just that, I somehow got to know that using USB as multiple COM ports is infact possible in PSoC. So I just wanted to try it out.
However, I dont think it can be done by mere use of the APIs.
So I was just looking for a clue as to how to go through with it? [just to increase my PSoC knowledge]
Any update on this ......anyone? Regards.
Hi there, I got to know that to actually achieve this [just incase anyone needs to...], one would require some changes to be made in the attached file........some application-level changes.
I am attempting to do the same. Could you advise me on how I can do this?
