Can Apalis TK1 support RS-422/485 interface?

Dear Support Team,

Can Apalis TK1 support RS-422/485 interface with latest V2.7b1 BSP? And if yes, how to configure to enable it?

Thanks
Simon

Unfortunately NVIDIA’s UART hardware does not feature any RS-422/485 functionality. That said one could probably emulate it in software at least to a certain degree meaning as long as the timing requirements are not too tight. However we at Toradex so far have not implemented any such. Alternatively one could run timing critical RS-422/485 protocols on the on-module Kinetis K20 MCU.

Dear Marcel,

got it , so is there any guide to implement RS-485 on K20 of Apalis TK1, especially on the communication between K20 and K1 part?

Thanks.

I guess asking for a complete guide describing this in detail asks a little bit too much but we do have the following article explaining at least how one may customise the firmware running on the K20.
