// This example shows how to buffer the read operations of a stream.
//
// Like "echo," it reads from the serial port and prints back the same thing.
// What's interesting with this program is that it reads the input in chunks of
// 64 bytes, even if it seems to read them one by one.

#include <StreamUtils.h>

ReadBufferingStream bufferedSerial{Serial, 64};

void setup() {
  // Initialize serial port
  Serial.begin(9600);
  while (!Serial)
    continue;
}

void loop() {
  // Even if it looks like the bytes are extracted one by one, they are actually
  // read by chunks of 64 bytes and placed in a buffer.
  while (bufferedSerial.available()) {
    Serial.write(bufferedSerial.read());
  }
