Serial multiplexer for Arduino¶
This library provides a simple way to create multiple virtual serial devices
that communicate over one physical serial connection. A virtual device can be
used as a drop-in replacement for Stream
like objects such as Serial
.
A service is needed on the host for multiplexing and demultiplexing and to create virtual ports. A Python client for Linux is provided as a reference implementation.
Please see ReadTheDocs for the latest documentation.
Quick start¶
Create multiple virtual serial devices and use them like the standard
Serial
object.
#include <serialMux.h>
SerialMux mux(Serial);
VSerial serialA(mux);
VSerial serialB(mux);
void setup() {
Serial.begin(9600);
}
void loop() {
serialA.println("Virtual device A.");
serialB.println("Virtual device B.");
delay(1000);
}
On the host, two virtual ports are created, e.g., /dev/pts/8
and
/dev/pts/9
. When we connect to one of these ports, we only see the
messages that are sent to that port.
$ picocom -q /dev/pts/8
Virtual device A.
