PModRS232 Use with Zedboard

[Robert Blancas]

I have a ZedBoard and would like to use one of the PMod interfaces to provide an RS-232 interface to a Windows computer.   I discovered the link https://reference.digilentinc.com/reference/pmod/pmodrs232/start and downloaded a ZIP file for the Reference Design Reference Project.  This ZIP file

included a pdf document and source code (main.c) that describes how to use the PModRS232 on a Digilent Cerebot II to provide an RS-232 interface (see excerpt from

document below).   My question is whether this can be done using a ZedBoard?   In other words, can I connect the PModRS232 to one of the PMod interfaces on the

Zedboard and then attach an RS-232 cable to USB cable to a PC and expect to communicate serially to a program such as TeraTerm?    Does the main.c program apply?  Please note that I'm already using the USB UART interface for serial communication, but need a second serial connection.

 

EXCERPT FROM PDF DOCUMENT:

This document describes the process of interfacing a Digilent Cerebot II to a personal computer using the PmodRS232.  Additionally any of Digilent’s AVR microcontroller boards, can be connected using the same technique. 

The hardware used in this tutorial: 
 
• Digilent Cerebot II • Digilent PmodRS232 • Digilent JTAG-USB programming cable • Microsoft Windows computer with serial port • Serial cable.

Hi @Robert Blancas,

You should be able to use the AXI UART IP Core with the Pmod RS232 or the Pmod USBUART. The use the c code as a reference but it will not work as is in SDK. Here is the Pmod BT2 IP Core that uses the UART communication that should be helpful with making your own IP. 

thank you,
