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.
