Virtueller
Com port? Das müsste dann ein Windows Treiber sein der ein
Com Port simuliert aber woran man ein usb gerät anschließt. Gibt es das?
USB darum, weil heute nicht mehr jeder Rechner eine serielle Schnittstelle hat.
Zitat:
Communication
The Arduino Uno has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual
com port to software on the computer. The '16U2 firmware uses the standard USB
COM drivers, and no external driver is needed. However, on Windows, a .inf file is required. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the USB-to-serial chip and USB connection to the computer (but not for serial communication on pins 0 and 1).
