I have 2 Due and Two DFR0063 I2C LCD. I cannot even pass i2C scanner. I always got No I2C devices found. I tried both SCL/SDA and SCL1/SDA1. For SCL1/SDA1, I do add 10K pull up resister. But still not work. I notice most of example is using Arduino Uno not Due. So I wonder maybe they just not work together. I actually just need any Chelp I2C device work smoothy with DUE not other board. Anyone recommend any goof I2C device for DUE?

Thanks

Joseph

    See this link about i2c problem on Due, this was several years ago so not sure whether this was fixed or not. – hcheung Jun 5 '20 at 9:23
