Arduino works with EEPROM
11 USD Arduino is connected with a screwscanner.
When scanning the stripcode, its presence is checked in the EEPROM SCH mass, if it is not, the impulse is sent to open the relay (the length of the impulse is 0.2 s), and the stripcode is recorded in the EEPROM mass.
If the stripcode is already in the EEPROM then the impulse is sent to include the lightloodium (the length of the impulse is 2 s).
The screensaver is connected to the D10 D11 (RX, TX).
The D9.
Lighting is D8.
The recording in the mass is cyclic, i.e. when recorded in the last EEPROM address the recording begins first, replacing the existing SC.

Good morning, I will be able to help you solve your task. You will only need information about the Arduino model and the data format from the scanner.

I worked on Arduino with EEPROM.
There are "nude" microschems and modules, so you can all work on the rail.
It should be consistent with the scheme of connection and the nuances of the work algorithm.
I'm going to write a sketch on the Arduino IDE.
by P.S. The night I was making a bet and something thought only about the external EEPROM microschems, but it is clear that the internal memory of Arduino can be applied...

Доброго дня. Скільки має бути штрих-кодів, чому саме єпром, ви отримували вже дані з сканера через ардуіно?
-
Доброго дня. Поки що зробив збереження в оперативній памьяті, потрібно щоб ШК зберігалися при виключені.
-
Ясно, могли б ви скинути документацію( модель) на сканер? По ньому є також запитання.

Да Присоединяюсь к вопросу алгоритм для сканера уже нсть млм его нужно реализовать-Поскольку сканер подключен к uart а обычно сканер rs-232(более высоковольтные) есть ли развязка uart =ttl типа max232
По моему опыту на ардуину сканер стабильно работает только на 9600 бод-У Вас на какой скорости?
-
Доброго дня.
Сканер підключається до ардуіно через st3232.
Для зчітування зі сканера вікористовую бібілотеку SoftwareSerial.
Зараз зчітую дані зі сканера і записую в масив в ОЗУ.
Сканер буде считувати ШК впродовж дня.

Виходить у вас багато що вже зроблено, проблема тільки у єпромі?
