hi, Mega do have the single i2c port but we can connect the many i2c device by address changing . my question is with two i2c device (eeprom and external ad converter )will hang out or malfunction in the single i2c port ?? . i saw some where google having the multiplexer will avoid malfunction and error does it true . what safest way to have the multiple i2c device in single i2c port
I2C allows connection to and control of multiple devices as long as each one has a unique address with no extra hardware
Get each of the devices working alone before you attempt to get them working together
