H3 Serial Port Arduino Serial Port To

Code in a sketch can use the same USB serial port to communicate with the PC by using the Arduino IDE Serial Monitor window, or a Processing application for example.

The Arduino MEGA 2560 and Arduino Due both have 3 extra hardware serial ports.

They may be referred to as USART (Universal Synchronous Asynchronous Receiver Transmitter) ports in the microcontroller documentation if they are configurable in both synchronous and asynchronous modes.

The port connects through a USB chip to the USB device port.

One that connects through a USB port chip to the USB device port on the board and three extra serial ports that connect to pins on one of the pin headers of the board.

Here pin 8 has been set as the receive pin and pin 7 as the transmit pin.

Serial ports 2 and 3 are referred to as Serial2 and Serial3.

If you try to compile the code for an Uno or other board that does not have Serial3 it will give an error.

But how can I program the Arduino Due using this serial port from an embedded Linux device.
