8 Brilliant Tips for Arduino Software Serial Newbies

Arduino is a great platform for beginners and experts alike. Whether you’re new to the Arduino software serial world, or an old pro looking to take their skills to the next level, this article will help you get up-to-speed with some of the most important aspects of using Arduino’s software serial library.

1) Serial data is transmitted in bytes rather than words

2) Serial data can only be sent one byte at a time

3) Receiving more than one byte at a time may cause collisions (data loss or corruption)

4) The baud rate must match between both devices

The Arduino software serial library allows a user to send and receive data using the TX/RX pins on an Arduino board. This article will cover some of the most important aspects about how this works, such as:

– Serial data is transmitted in bytes rather than words

– The RX pin can only be read one byte at a time so if you want more than one byte from the receiver device then collisions may happen (this also means that if the baud rate doesn’t match between both devices there is potential for collision)

– Sending or receiving too many bytes at once may cause buffer overflows and result in lost messages or corrupted data being received by either end.

If any of these concepts are unclear please feel free to comment below and I will make sure that the post is updated with any additional information.

-Sending or receiving too many bytes at once may cause buffer overflows and result in lost messages or corrupted data being received by either end.

There are two methods of setting up software serial:

-Including code from an external library which must be downloaded before use, such as SoftwareSerial() function included in Arduino IDE

.

-Including a default setup as part of your sketch, such as the Serial object in Processing or PDE (this is what we’ll be discussing)

To transmit, you must initialize an instance of SoftwareSerial with pins that are connected to Rx and Tx on another device:

SoftwareSerial mySer(RX_pin, TX_pin); // Connect RX pin to signal from receiver; connect TX pin to transmitter. This will allow for serial input/output by using the ‘read()’ like function which reads bytes at time from one end and writes them into a buffer called BUFFER until it’s full then moves onto reading data again from other side. The downside of this method is that the read() function can only take one byte at a time, so this is not an efficient way of reading large amounts of data.

To transmit, you must initialize an instance of SoftwareSerial with pins that are connected to Rx and Tx on another device:

M ySer(RX_pin, TX_pin); // Connect RX pin to signal from receiver; connect TX pin to transmitter. This will allow for serial input/output by using the ‘read()’ like function which reads bytes at time from one end and writes them into a buffer called BUFFER until it’s full then moves onto reading data again from other side. The downside of this method is that the read() function can only take one byte at a time, so this is not an efficient way of reading large amounts of data.

We’ll also want to set a baud rate for serial communication (defaults at 115200). The following function sets the number of bits per second and parity:

mySer.begin(9600); // BPS in bits/sec mySer.setParity(true); // Parity will be odd or even depending on your preference if you’re using hardware pins else use false mySer.setDataMode(“ascii”); // Data transfer will be as either ASCII text or binary which one depends on user’s preference// This last step is needed before we can start transferring data between our devices using Serial Communication }}
