Hello everybody,

I have my M24SR working with my MCU :) I can read the contents of the tag. However, after a read from MCU, I cannot write the tag if I do not remove power from it. I have performed the DESELECT command and also DE_INIT my I2C. All the communication procedure takes place perfectly.

The tag is connected to MCU by means of the two I2C wires, one VCC and one GND. I do not have GPO since to save one pin I work by polling.

Have a nice day and let me know your opinions about this subject! :)
