Can anyone tell me the voltage level of the serial channels of the WAV trigger? I want to communicate with it from an ATtiny chip running at 5v, but I notice that the RXD line on the WAV Trigger is pulled up by 3.3v. I'm not knowledgeable enough to know whether that will cause any problem when a 5v signal level is applied to it. Can anyone alay my probably misplaced fears please?
