Hi Snehal


It seems like the i2c is working if it is able to probe the i2c bus.

What is the expected value that the i2cget command should return?


Regards

Jingyang, Teh

Hello Jingyang,

Expected value is whatever we write as in this case 255.

Basically I'm trying to interface rtc ds3231 to this i2c bus. What would be the appropriate approach to use this I2C bus to interface external rtc breakout board.

Can you please help me with approach.

Thanks,
