Serial communications provide an easy and flexible way for your Arduino board to interact with your computer and other devices. This chapter explains how to send and receive information using this capability. Chapter 1 described how to connect the Arduino USB serial port to your computer to upload...
Serial: serial port object. See the list of available serial ports for each board on the Serial main page. val: a value to send as a single byte. str: a string to send as a series of bytes. buf: an array to send as a series of bytes. len: the number of bytes to be sent fro...
I know IO4, IO16, and IO17 work because they are connected to the LED in the unmodified CYD. I can see in the o’scope the proper 0.2v-3.3v serial data stream on IO16. I setup and started UART(2) using: HardwareSerial SerialPort(2) ; ...
‘b’ before the string to send. This will encode the string to bytes, because you can only send bytes through Serial. Any data which is not a byte or byte array must be converted before being sent. If you just try to send the string like that, you’ll get this error ” TypeError...
