Пропуски при коммуникации по i2c.

Связь между контроллерами по i2c.
Master задает и контролирует параметры у 6 Slaves.
При тестовом прогоне кода обнаружилась НЁХ.
Функция SetTemperatureToController возвращает false.
Похоже что линия i2c перестает работать с некоторой периодичностью на 0,1 сек.
В чем может быть проблема?

Master code:

unsigned int Command = 0;
char TwoBytes [2];

bool SetTemperatureToController (double TemperatureToSet, byte ControllerToSet) {
  //Отправить температуру
  Command = TemperatureToSet * 10;
  Wire.beginTransmission(ControllerToSet);
  Wire.write(Command >> 8);
  Wire.write(Command & 0xFF);
  Wire.endTransmission();
  
  //Команда на получение температуры
  Command = 3;
  Wire.beginTransmission(ControllerToSet);
  Wire.write(Command >> 8);
  Wire.write(Command & 0xFF);
  Wire.endTransmission();
  
  //Получить температуру
  Wire.requestFrom(ControllerToSet, 2);
  TwoBytes[0] = NULL;
  TwoBytes[1] = NULL;
  TwoBytes[0] = Wire.read();
  TwoBytes[1] = Wire.read();
  Command = 0;
  Command = ((unsigned int)TwoBytes[0] << 8) + ((unsigned int)TwoBytes[1]);
  
  //Проверка на успешное задание температуры
  if (TemperatureToSet == (double)Command/10) return true;
  else return false;
}

Slave code:

unsigned int Command;
char TwoBytes [2];

void receiveEvent(byte bytes) {
  //Прочитать команду
  TwoBytes[0] = NULL;
  TwoBytes[1] = NULL;
  if (bytes == 2) {
    TwoBytes[0] = Wire.read();
    TwoBytes[1] = Wire.read();
  }
  Command = NULL;
  Command = ((unsigned int)TwoBytes[0] << 8) + ((unsigned int)TwoBytes[1]);
  //Serial.println (Command);

  //Записать температуру в TemperatureToSet
  if (Command < 10000 && Command >= 100) {
    TemperatureToSet = (double)Command / 10;
  }
}

void requestEvent() {
  //Отправить температуру из TemperatureToSet
  if (Command == 3) {
    Command = TemperatureToSet*10;
    Wire.write(Command >> 8);
    Wire.write(Command & 0xFF);
    Command = NULL;
  }
}

Тестовый код:

for (double d = 10.0; d < 130.0; d+=0.5){
    if (SetTemperatureToController (d, 1)){
      Serial.print(millis()); Serial.print(": "); Serial.println(d);
      delay(100);
    }
    else {
      Serial.print(millis()); Serial.print(": "); Serial.println("false");
    }
  }

Что получаю в терминале:

Re: Пропуски при коммуникации по i2c.

Если ты хочешь, чтобы кто-то действительно попытался разобраться, выкладывай коды полностью - со всеми описаниями, инклудами и т.п. Без этого здесь будет только тыкание пальцем в небо и глум со срачем, ибо неxyй.

Re: Пропуски при коммуникации по i2c.

Очень врядли кто-то захочет разбираться в коде. Да и незачем, там кроме математики ничего нету.
Использую пару библиотек
#include <PID_v1.h>
#include <Thermistor.h>
#include <NTC_Thermistor.h>
#include <Wire.h>
#include <EEPROM.h>

Программа работает просто. Рассчитывает мощность нагрева чтобы достичь заданой температуры опираясь на показания ADC.
В мастер коде используется только то, что написал в 1 посте (Master code: && Тестовый код:).
К на i2c еще подключено 2 девайса, RTC и тачскрин. Оба используются без прерываний, мастер контроллером.

И правильно делает, что перестаёт. Ну не может он быстрее. Здесь вся суть в буферах и loop-е!  big_smile

Re: Пропуски при коммуникации по i2c.

Похоже что линия i2c перестает работать с некоторой периодичностью на 0,1 сек.

Датчики какие? DS18B20 ? Если да, так измерение температуры занимает время.

Использую термистор. Функции delay() почти не использую, и в любом случае Slave работает по прерываниям, а Master тупо отрабатывает функци без прерываний.

Спецом сделал очищенный скетч от всего. Все то же самое. Периодически на Slave приходит мусор. Я даже скорость до 10к уменьшил.

Master:

#include <Wire.h>

unsigned int Command = 0;

  Command = 3;
  Wire.beginTransmission(ControllerToSet);

  Wire.write(Command & 0xFF);

Не перестаёт а даже и не начинала. Лень, конечно, двигатель прогресса но только в обратную сторону! https://www.arduino.cc/en/Reference/WireRequestFrom

Вы случайно, не перепутали резистор с конденсатором. На фото "подтяжки" подозрительно выглядят.  smile

Ну и зачем мне это нужно? Даже Пегги Грипал не предлагают и даже не погладят. smile Хай самi допетрують. Хотел подсказать принципиальные ошибки - передумал. Лично мне это не нужно. Как говорится в народном фольклёре: "Кто хочет тот и платит"!

Re: Пропуски при коммуникации по i2c.

Использую термистор. Функции delay() почти не использую, и в любом случае Slave работает по прерываниям, а Master тупо отрабатывает функци без прерываний.

По I2C что подключено? 
Может соизволите сразу предоставить всю информацию?
Схему?
В противном случая Вас просто будут посылать куда по дальше...
