I2C_GenerateStart(ENABLE);

while(!I2C_CheckEvent(I2C_EVENT_MASTER_MODE_SELECT));

/* Send EEPROM address for write */

I2C_Send7bitAddress(0x70, I2C_DIRECTION_TX);

/* Test on EV6 and clear it */

while(!I2C_CheckEvent(I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED ));

I2C_ClearFlag(I2C_FLAG_ADDRESSSENTMATCHED);

/* Send Address (on 2 bytes) of first byte to be written & wait event detection */

I2C_SendData(0xC8); /* MSB */

/* Test on EV8 and clear it */

while (!I2C_CheckEvent(I2C_EVENT_MASTER_BYTE_TRANSMITTING));

I2C_SendData(0xaa); /* LSB */

/* Test on EV8 and clear it */

while (!I2C_CheckEvent(I2C_EVENT_MASTER_BYTE_TRANSMITTING));//////Stuck here my code

I2C_GenerateStop(ENABLE);
