To my surprise, I found no usage of either TX or RX in any active code, only their definitions in the 'variant' files.\r\n\r\nIf this is confirmed, should the RX/TX pin definitions be depreciated or even removed from the 'pins_arduio.h' variant files?\r\n\r\n[txrx_feather]:\r\nhttps://github.com/espressif/arduino-esp32/blob/master/variants/feather_esp32/pins_arduino.h#L17#L18"},"comment":{"url":"https://api.github.com/repos/espressif/arduino-esp32/issues/comments/404924458","html_url":"https://github.com/espressif/arduino-esp32/issues/1607#issuecomment-404924458","issue_url":"https://api.github.com/repos/espressif/arduino-esp32/issues/1607","id":404924458,"node_id":"MDEyOklzc3VlQ29tbWVudDQwNDkyNDQ1OA==","user":{"login":"me-no-dev","id":12663778,"node_id":"MDQ6VXNlcjEyNjYzNzc4","avatar_url":"https://avatars3.githubusercontent.com/u/12663778?v=4","gravatar_id":"","url":"https://api.github.com/users/me-no-dev","html_url":"https://github.com/me-no-dev","followers_url":"https://api.github.com/users/me-no-dev/followers","following_url":"https://api.github.com/users/me-no-dev/following{/other_user}","gists_url":"https://api.github.com/users/me-no-dev/gists{/gist_id}","starred_url":"https://api.github.com/users/me-no-dev/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/me-no-dev/subscriptions","organizations_url":"https://api.github.com/users/me-no-dev/orgs","repos_url":"https://api.github.com/users/me-no-dev/repos","events_url":"https://api.github.com/users/me-no-dev/events{/privacy}","received_events_url":"https://api.github.com/users/me-no-dev/received_events","type":"User","site_admin":false},"created_at":"2018-07-13T19:02:28Z","updated_at":"2018-07-13T19:02:28Z","author_association":"MEMBER","body":"@stickbreaker that is a different thing. we are talking about the default pins currently 😄 "}}
