Hi, I need to simulate a sensor that communicates via rs-232, using 8 data bits, 1 odd bit and 1 stop bit. I'm using a Leonardo as "master" and the Uno as the "slave/sensor". Looking at the microprocessors datasheets, I only need to change the UPMn1 register when I initialize the Serial in setup()…

Serial parity change in UNO/Leonardo
