That's right, the OLED was necessary to show how many codes are used and how many been left and to show in what menu the module is.
But I have to solve some challenges (mostly the code for the program) before I can verify if the theoretic idea works like expected. Some of this challenges sounds trivial but I haven't done this so far and have trouble with it. E. g. the reading and writing to a ST95P08 EEPROM. This EEPROM works over SPI (not IC2 like mine) and I have problems to get it working on an Arduino.
So if anyone can help me with the code and has a solution he is welcome to help me.
