For Arduino boards with more than one serial port the HardwareSerial class will define numbered Serial objects;For a single Serial port (Arduino Uno/Nano) you write: Serial.begin(115200);For multiple Serial ports you writeSerial.begin(115200); Serial1.begin(9600);...
类库的详细介绍见[Arduino Reference SoftwareSerial Libray](https://www.arduino.cc/en/Reference/softwareSerial "Arduino Reference SoftwareSerial Libray")。 在Reference 中指出,软串口有着以下一系列的局限性: The library has the following known limitations: > - If using multiple software serial ports, ...
the ATmega4809 can be found in products like the Arduino Uno WiFi Rev2 and the Arduino Nano Every. Some of their key features include multiple serial ports, SPI and i2c interfaces, built-in programmable logic, up to 16 analog input pins, and an analog comparator with a built-in programmabl...

An Arduino Uno has a single hardware serial port, but serial communication is also possible using software libraries to emulate additional ports (communication channels) to provide connectivity to more than one device. Software serial requires a lot of help from the Arduino controller to send and ...
It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. ...

at the UNO and MEGA use Reply maniacbug May 18, 2012 at 7:14 pm Try posting on the Arduino forums. Reply Zhen June 9, 2012 at 8:53 pm Awesome tutorial on getting the 1284p to work. However, I’m running into some problems getting both serial ports to work at the same ...
An Arduino core for ATmega8535, ATmega16, ATmega32, ATmega164, ATmega324, ATmega644 and ATmega1284, all running theUrbootbootloader. Most Arduino UNO-compatible libraries will work with this core. If not, it's fairly straightforward toport a library. This core requires at least Arduino IDE v1....
