I am creating a DMX receiver circuit. The dmx that is received from a controller (USB DMX dongle) is converted via a transceiver (SN75176BP) to a signal which can be understood by an ATMEGA328P.
I now have the problem that it is not recognized. When I measure on my circuit at RX I get the signal that can be seen in the image. I think it is not working due to the fact that a 40+ Volts signal is supplied which can not be read by the ATMEGA328P.
