Hi Experts,


I have a FRDM K22F board (MK22FN512VLH12) and  connected one light sensor to it.


I have connected I2C sensor on I2C1 module of the board.[Pin55 as I2C1_SCL & Pin 56 as I2C1_SDA] and configured it as I2C Master.


Slave address for my device is 0x23. I have modified freertos_i2c_frdmk22f code to test it.


When i am trying to write on this slave address, I am getting error [Error code:- 0x451:- kStatus_I2C_Addr_Nak. NAK received during the address probe]


Can you please help here,where i did mistake and how to proceed.
