Explanation

With this library you can convert any type of data to an Arduino Stream. First of all you have to include the library.

#include <BufferStream.h>

You can read data from a Stream or write data to a Stream. To read data you have to set the buffer from where you want to read and the size of that buffer.

String data("This is the string!");
ReadBufferStream stream(data.c_str(), data.length());

Now you can read the data of the srteam like it was an Arduino Serial.

while (stream.available()) {
  Serial.print((char) stream.read());
}

To write data you have to set the buffer and the size buffer where you want to write.

WriteBufferStream stream(data, 100);

Now you can send or write data like it was an Arduino Serial.

// Add data to stream
  stream.print("Hello");
  stream.print(' ');
  stream.print("WriteStream!");

// Add the '\0' character at the end of the stream
  stream.write(uint8_t('\0')); 


Examples

You can see a read and write String examples in the following paragraphs:

ReadString

// BufferStream library example
// by Industrial Shields

#include <BufferStream.h>

String data("This is the string!");

////////////////////////////////////////////////////////////////////////////////////////////////////
void setup() {
  // Create stream from data
  ReadBufferStream stream(data.c_str(), data.length());

  // Print data from the stream
  Serial.begin(9600UL);
  while (stream.available()) {
    Serial.print((char) stream.read());
  }
  Serial.println();
}

////////////////////////////////////////////////////////////////////////////////////////////////////
void loop() {
  // Nothing to do
}


WriteString

#include <BufferStream.h>

////////////////////////////////////////////////////////////////////////////////////////////////////
void setup() {
  // Create stream from data
  char data[100];
  WriteBufferStream stream(data, 100);

  // Add data to stream
  stream.print("Hello");
  stream.print(' ');
  stream.print("WriteStream!");

  // Add the '\0' character at the end of the stream
  stream.write(uint8_t('\0'));

  // Print data
  Serial.begin(9600UL);
  Serial.println(data);
}
