ptz Posted October 29, 2018 Share Posted October 29, 2018 [H5: Nanopi neo core 2] I observe the UART Rx line to be influenced by the RTS line which I am using during sending. Is there a way to enable an internal pull-up on Rx so that this doesn't happen? I suspect it's the cause of communication errors that I observe. I confess that I am currently on a FriendlyCore 4.16 build, but I wouldn't expect such an issue to be too distribution-specific. Link to comment Share on other sites More sharing options...
