24LC32 arduino driver may need update; not working ?

Post by garberw »

I have 24LC32 set up I2C in arduino circuit with no I2C conflicts. Arduino is attached to raspberry pi where I run Arduino IDE. There are two similar arduino circuits with an 24LC32 attached to another raspberry pi. Suddenly two of them will not even run the multibyte write example or any examples in adafruit fram library. Substituted a new 24LC32 in one of the circuits and that did not work either. I bought 4 of these EEPROMs so I hope I can get them working soon please :-)

could someone update the driver or give me a clue if I am doing something wrong?
I bet it is due to an update to the arduino IDE or CLI compiler.
Also I had to reset the two arduinos that are not working with the reset button multiple times.
Could that cause it to break the 24LC32 ?

sorry it was a wiring fault on my part. Please forgive me I have very shaky hands. Also the breadboard failed. I soldered the whole circuit and it worked. But with the new arduino ide you can not see the output of the write_multibyte.ino example for the Adafruit FRAM library. I put in a watchdog delay and it showed up.
