It will return a byte array type object if anything was received already. Once the object is created you read data in with read( numbytes) where you can specify the max number of bytes. See the diagrams below for help with finding the correct pins on your board. While these pins are labeled on most of the boards, be aware that RX and TX are not labeled on Gemma, and are labeled on the bottom of Trinket. We provide the pins we'd like to use, board.TX and board.RX, and we set the baudrate=9600. # SPDX-FileCopyrightText: 2018 Kattni Rembor for Adafruit Industriesįirst we create the UART object.
