Serial Communication串口通信,有4个串口 RXD and TXD are the serial pins used to transmit and receive serial data i.e. Rx represents the transmission of data while Tx used to receive data. There are four combinations of these serial pins are used where Serail 0 contains RX(0) and TX(1), ...
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. 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, ...
PWM:Pins 2 to 13 and 44 to 46 provide 8-bit PWM output with the analogWrite() function. SPI:Pins 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS) support SPI communication using the SPI library. They are also broken out on the ICSP header, which is compatib...
A SoftwareSerial library allows for serial communication on any of the ADK's digital pins. The ATmega2560 also supports TWI and SPI communication. The Arduino software includes a Wire library to simplify use of the TWI bus; see the Wire library for details. For SPI communication, use theSPI...
Support TWI communication using the Wire library. Note that these pins are not in the same location as the TWI pins on the old Duemilanove or Diecimila Arduino boards. See also the mapping Arduino Mega 2560 PIN diagram. The Mega 2560 has 16 analog inputs, each of which provide 10 bits ...
