Im working on a project that is using a Rabit microcontroller that runs on 3.3v logic and im wondering if there is anything special I need to do to be able to connect an Arduino Duemilanove to it using serial communication.
The Rabit is the master microcontroller and it will periodically ask the arduino for information. Im not too familiar with serial communication but im thinking i will need a 3.3v to 5v logic level converter for this to work correctly?
Is my assumption correct or will i just be able to connect the TX directly to the Rx?
Thanks in advance
