Запись/чтение в AT24C16.

[DSerge]

Поясните "на пальцах" или примером в СИ как байтовый массив записать в несколько блоков в AT24C16.
Проблема: не могу перейти в следующий блок при заполнении предыдущего.

[ForcePoint]

ЕМНИП, послать Stop и начать цикл записи снова, с новым адресом:

The data word address lower three bits are internally incremented following the receipt of each data word. The higher data word address bits are not incremented, retaining the memory page row location. When the word address, internally generated, reaches the page boundary, the following byte is placed at the beginning of the same page. If more than sixteen data words are transmitted to the EEPROM, the data word address will “roll over” and previous data will be overwritten.

Там страницы. Адрес инкременируется лишь до конца страницы. Вот пример моего кода:

char EEPROM_RW (EEPROM_StructTypeDef * EEPROM)
{
	char m_adrs[2], Result = 0, BytesToHandle;
	
	/* Calculate start address */
	m_adrs[1] = (char)EEPROM-›Mem_adrs;
	m_adrs[0] = (char)(EEPROM-›Mem_adrs ›› 8);
	
	/* Calculate bit mask */
	BytesToHandle = m_adrs[0] & (EEPROM-›PageSize - 1);
	
	/* Apply bit mask. If first part of page exist */
	if (BytesToHandle)
	{
		if (EEPROM-›isWriting)
		{
			/* Perform writing */
			Result = EEPROM-›WritePage(EEPROM-›I2C_Adrs, m_adrs, 2, EEPROM-›buf, BytesToHandle);
			EEPROM-›delay_func(EEPROM-›PageWriteTime);
		}
		else
			/* Perform reading */
			Result = EEPROM-›ReadPage(EEPROM-›I2C_Adrs, m_adrs, 2, EEPROM-›buf, BytesToHandle);
		
		EEPROM-›size -= BytesToHandle;
		EEPROM-›Mem_adrs += BytesToHandle;
	}
	if (!EEPROM-›size || Result) return Result; //nothing to write any more

	/* Reading or Writing full pages */
	do
	{

			Result = EEPROM-›WritePage(EEPROM-›I2C_Adrs, m_adrs, 2, EEPROM-›buf, EEPROM-›PageSize);
			EEPROM-›delay_func(EEPROM-›PageWriteTime);
		}
		else
			/* Perform reading */
			Result = EEPROM-›ReadPage(EEPROM-›I2C_Adrs, m_adrs, 2, EEPROM-›buf, EEPROM-›PageSize);
		
		/* Calculate new offset */
		EEPROM-›buf += EEPROM-›PageSize;
		EEPROM-›size -= EEPROM-›PageSize;
		EEPROM-›Mem_adrs += EEPROM-›PageSize;
		m_adrs[1] = (char)EEPROM-›Mem_adrs;
		m_adrs[0] = (char)(EEPROM-›Mem_adrs ›› 8);		
		
	}while(EEPROM-›size ›= EEPROM-›PageSize);
	
	if (!EEPROM-›size) return Result; //nothing to write any more
	
	/* Read or write the rest of data */
	if (EEPROM-›isWriting)
	{	
		/* Perform writing */
		Result = EEPROM-›WritePage(EEPROM-›I2C_Adrs, m_adrs, 2, EEPROM-›buf, EEPROM-›size);

	}
	else
		/* Perform reading */
		Result = EEPROM-›ReadPage(EEPROM-›I2C_Adrs, m_adrs, 2, EEPROM-›buf, EEPROM-›size);
			
	return Result;
