Would there be any code whihc I can use as reference for I2C or atleast guide me how to configure PCA9698 for turning LED on/off ? What would be the sequence of device (slave) address, output configuration register and command register for output?</P> Mon, 21 Jun 2021 17:25:12 GMT hfabbasi 2021-06-21T17:25:12Z https://community.nxp.com/t5/Kinetis-Microcontrollers/PCA9698-I2C-setting/m-p/1295565#M60892 <P>I am new to I2C protocol and trying to turn LED on/off connected to bank 0, pin 0 in MCUXpresso software by NXP.
