Multiple Serial Ports Proteus Simulation:įor the best understanding I am going to explain this with the help of a Proteus simulation.ĭownload the Proteus Simulation: SoftwareSerialĪs you can see I have connected a Bluetooth module and a GSM module with the Arduino’s pins 2, 3, 7, and 8. The Arduino’s default serial port should only be used for the debugging purposes. While using the Arduino Uno or Arduino Nano even if you are using one serial device never use the Arduino’s default serial port for the communication with other devices. You can connect any of the two devices with the Arduino’s default serial port, but, what about the other serial device?Īt this point you will need the SoftwareSerial library which can be used to create multiple serial ports. Let’s for example you are working on a project in which you are required to connect two serial devices GSM Sim900A and a Bluetooth module HC-05 or HC-06, or any other serial device. But when it comes to the multiple Serial devices then the Arduino default serial port becomes insufficient. Using the Arduino’s default Serial Port we can connect only one serial communication supported device. In the case of Arduino Uno, we have only one serial port which is available on Pin0 and Pin1. So using the Arduino Mega you can communicate with 4 serial devices at the same time. It’s based on your choice, if you want to use Arduino Mega then I don’t think so you will need the SoftwareSerial library, as in Arduino Mega we have a total of 4 hardware serial ports that can communicate with different serial communication supported devices.

Using the SoftwareSerial library we can create multiple software serial ports with speeds up to 115200bps. The SoftwareSerial is basically a library that enables the Serial Communication on digital pins other than the Serial Port. I would appreciate your support in this way! SofwareSerial:

I may make a commission if you buy the components through these links. Without any further delay, let’s get started!!! I will explain this with the help of a Proteus simulation and will share with you some advanced level projects in which the SoftwareSerial library is used. Why is it used in the Arduino Uno or Arduino Nano programming? How do we know when to use this library? You will get answers to these questions.

When and why we need the SoftwareSerial?.

If using multiple software serial ports, only one can receive data at a time.

The library has the following known limitations: The version of SoftwareSerial included in 1.0 and later is based on the NewSoftSerial library by Mikal Hart. A parameter enables inverted signaling for devices which require that protocol. It is possible to have multiple software serial ports with speeds up to 115200 bps.

The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name " SoftwareSerial"). This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer.

The native serial support happens via a piece of hardware (built into the chip) called a UART. The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). Reference Language | Libraries | Comparison | Changes
