спасибо за ответ . Но в SerialEvent какой-то косяк . Как будто это не прерывание. Учебник так и пишет ,что 

оно обрабатывается после прохода всего loop {}.  Неужели среда Ардуино НАСТОЛЬКО урезана ?

урезана относительно чего , языков высокого уровня ?? )

организуйте алгоритм проги чтоб в прерывании выполнялось как можноо меньше вычислений 

Делается так: заменяете содержимое файлов HardwareSerial.h и HardwareSerial.cpp , расположеных Arduino\hardware\arduino\cores\arduino\.

Или просто добавьте в свои файлы выделенные строки, сохраняете файлы, перезапускаете IDE. Проверялось на версии 1.0.5, поэтому лучше и использовать версию 1.0.х.

Пример использования:

void setup() {
  Serial.begin(9600);
  Serial.attachSerialInterrupt(SerialInterrupt);
}

void loop() {

}

void SerialInterrupt() // ваша функция
{
  // делаем че хотели
}

Вот и будет вам прерывание по принятому байту.

Пробовал на1.0.4 и 1.0.5  .   Вставлял строки и заменял весь файл. Перестал компилировать,выдает кучу ошибок.Что-то я не так делаю...  

наверное...

спасибо. буду в atmel studio писать...

Что-то не то у вас там написано - прерываеия вот так обрабатываются:

ISR(USART_RXC_vect){ 
   byte value = UDR;             //read UART register into value
   // тут обрабатываете принятый байт...
}

Для меги 2560

USART0_RXC_vect

USART1_RXC_vect

USART2_RXC_vect

И там еще куча векторов прерываний на разные случаи жизни в iomxx0_1.h а для UNO в iom328p.h

Да нет, это у вас что то не то написано.

Вектор с именем USART_RXC_vect для ATmega8/16/32, для ATmega88/168/328/1280/2560 имя вектора USART_RX_vect (USART0_RX_vect).

Ну это ладно. А попробуйте ка скомпилировать то что вы рекомендуете:

void setup() 
{
  Serial.begin(9600);
}

void loop() 
{

}

//ISR(USART0_RX_vect){  // Mega
ISR(USART_RX_vect){
   byte value = UDR0;             //read UART register into value
   // тут обрабатываете принятый байт...
}

Так вот как только вы попытетесь использовать эти обработчики вместе с классом Serial, компилятор будет ругаться благим матом, потому как Serial уже их использует для своих нужд.

Ну а коль хотите пользоваться обработчиком самостоятельно, будьте добры изучить как инициализировать UART, как передавать байты и т.д.

Например:

void setup()
{
  UartInit();
}

void UartInit()
{
  UCSR0B |= (1<<RXEN0)  | (1<<TXEN0) | (1<<RXCIE0);    // UART RX, TX 
  UCSR0C |= (1<<UCSZ01) | (1<<UCSZ00)             ;    // Asynchron 8N1

  UBRR0H = 0;
  UBRR0L = 103; //Baud Rate 9600
  sei();
}

//ISR(USART0_RX_vect)
ISR(USART_RX_vect)
{
  char b;
  b = UDR0;
}

Извиняюсь за старую тему , но хотелось бы разобраться и понять ...

Проблема в том , что после изменения и сохранения файлов перестают компилироваться все программы. В каком редакторе можно их изменять ? Я пробовал в блокноте и в Word . Arduino  установлен из  zip  файла .

Спасибо .
