USB serial adapter for SCI in 8 bits + adress mode + parity?

Max Klob

Hello,

Is there a USB to serial adapter that support the SCI mode with 8 data bits + address bit + parity bit?

Or at least an adapter for 8 data bits + address bit ?

I spent some time searching on the Internet but I only found answers telling to trick the parity bit to behave like the address bit.

In there a better solution?

Thanks for your help!

Are you asking if there is a CDC USB driver which supports Address mode?

Hello Sal,

I don't know how to answer your question.
I am looking for something like that:

And a kind of device that would support 8 bits + address at least.

And eventually with the support of parity bit too!

Thank you!

I don't think I can help too much. I would search around the internet and see if there is a USB CDC class driver which supports address mode.

Which device are you using? UART or SCI support address mode. You may be able to implement this with UART/SCI instead of USB.

Hi Sal,

Sorry for the delay I forgot this post!
Anyway, it seems to be quite complicated since 9 bits or 10 bits UART are not that common.
I think I'll implement 2 communication modes. One for MCU 2 MCU (using 10 bits SCI) and one for MCU 2 PC (using classical UART).

Thanks for your help!
