I2C1 發送data I2C2接受data

farmer30175

大家午安


想詢問一下各位大大
用cubeMX生成了一個檔案
再下去修改

主要目的是想從i2c1(pb6,7)發送一組字串，讓i2c2(pb10,11)接收一組從i2c1發送的訊息
但不清楚為什麼debug mode 總會死在
/*receive an amount of data in slave mode*/
        if(HAL_I2C_Slave_Receive_IT(&hi2c2,(uint8_t*)slave_buffer_rx,MASTER_TX_SIZE)!=HAL_OK)
        {
                if(HAL_I2C_GetError(&hi2c2)!=HAL_I2C_ERROR_AF)
                {
                        Error_Handler();
                }
        }

還請大大幫忙  謝謝平台
