Dear Members,

Where can I find from software development kit the example for writing and reading from I2C EEPROM ?

Thanks

You need pullups somewhere on the I2C bus - this is a basic requirement for any I2C bus.

still can not see 24C16 address on TWI scanner, is my supply to low ? I checked, VCC=2.4V ?

Have you used an oscilloscope or analyser to see what's happening on the wires?

[RixtronixLAB]

Ok, I'll see with analyzer and posted, thanks

I reckon, I have insufficient power for this 24C16 PU27, I will try with external 3.3V, I keep posted, thanks
