Hi All
The reference manual mention as below spec.
Could you tell me the direction control via CTS_B pin is hardware auto switch or software handle switch?
Thanks.
Solved! Go to Solution.
Hi Felix
seems it is hardware as descrbed in sect.53.7.1 Generalities, Figure 53-12. RS-485 driver connection
i.MX6ULL Reference Manual :
The CTS_B pin can be used to control RS-485 output driver outside the chip.

Yes, Felix. Through software control.
We are using RS-485 driver direction control via gpio on MYIR MYS-6ULX board.
Through CTS_B might be also possible.
But for any ways, you need to configure dts.
Hi Linda
Thank for your reply.
So direction control is software control, right?
it is not hardware will auto detect switch timing.
