zynq7 Processing System is used and it is planned to output as PL GPIO (EMIO).
I know how to output from PL externally, but PS register? signal? I'm not sure if it should be declared.
I read Zynq-7000 TRF but I didn't understand.
GPIO declares with 18 bits.
I don't know anything about PS.Thanks.

Have you ever used MIO? If so, EMIO is similar to the MIO, you need to initilize it and control it in the sdk code, they used the same C code. If you never used mio, suggest you can search an example code on the google, there are many code on the website and you can modify based on these example.
