Utilizing UART with GPIO pins in de-10 nano

[HAF]

hello, 

I want to receive data  by external microcontroller through GPIO, and then use this data in my code as input, I read about UART RS232 but I am not sure how to use it. please provide your gaudiness. 

best regards,

Hi,

You need to use the RS232 IP in platform design and connect this IP using hps2fpgaslaves with hps ip. assign the base address and pin assignments for RS232 ip(RX & TX pins).

Later, in linux add this rs232 entry in your device tree.

For this I suggest you to refer the Cyclone V GHRD/GSRD on rocketboard. This will help you how the design got created and the software requirement.

I’m using SOC, DE-10 nano.
Can't I just receive data via GPIO wired connection?

Hi,

you will be using the two GPIO for UART IP core and this will be control from the HPS.

And we do have the UART IP driver with the HPS.

Please refer the below link and chapter-11.
