Send And Receive Data with I2C

[mahmoud boroumand]

Hello

I Have stm32f107vct6 And I Want to send data from master to slave I2C Protocol . I Wrote Some code But it didn't work.

Do you Have complete Example for i2c?

this is my code

Master:

while(1){
	while(!__HAL_I2C_GET_FLAG(&hi2c1,I2C_FLAG_BUSY))
			HAL_I2C_Master_Transmit(&hi2c1, 0x80, buffer,20, 10); 
	
	
		HAL_Delay(500);
	
	
}

Slave:

	 hi2c1.Instance = I2C1;
 hi2c1.Init.ClockSpeed = 400000;
 hi2c1.Init.DutyCycle = I2C_DUTYCYCLE_2;
 hi2c1.Init.OwnAddress1 = 0x80;
 hi2c1.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT;
 hi2c1.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE;
 hi2c1.Init.OwnAddress2 = 0;
 hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE;
 hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE;
	
 if (HAL_I2C_Init(&hi2c1) != HAL_OK)
 {
 Error_Handler();
 }
	
	HAL_I2C_EnableListen_IT(&hi2c1);
 
 
void I2C1_EV_IRQHandler(void)
{
 /* USER CODE BEGIN I2C1_EV_IRQn 0 */
		HAL_I2C_Slave_Receive(&hi2c1,buffer,20,10000);
 
 /* USER CODE END I2C1_EV_IRQn 0 */
 HAL_I2C_EV_IRQHandler(&hi2c1);
 /* USER CODE BEGIN I2C1_EV_IRQn 1 */
 
		
 /* USER CODE END I2C1_EV_IRQn 1 */
}
 
 

on my code I2C1_EV_IRQHandler call success but data doesn't receive anything.

There are several examples in the CubeMX repository. Here is one of them:
