DFRO316 MCP3424 and STM32

[PWaiba]

I am trying to know the status of MCP3424, either it is connected or not to the master STM32 with defined address 0x68. The ADC module gets connected with the Arduino in same address but using STM32, I am not able to get connected with the following code:

if((HAL_I2C_IsDeviceReady(&hi2c1, 0x68 << 1, 100, 1000))==HAL_OK){

HAL_UART_Transmit(&huart2, "device connected\r\n", 10, 10);

}

else{

HAL_UART_Transmit(&huart2, "no device\r\n", 100, 10);

}
