It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 54 digital input/output pins (of which 14 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. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 ( datasheet). Now for install process of Arduino Mega 2560 drivers, now you have to select right drivers for your Arduino mega 2560 board, Click on the browse button for Selecting right Drivers. Now open Unknown device’s Properties Tab and click on update driver link to install your mega 2560 drivers. First Download one the file.The Arduino Mega is a microcontroller board based on the ATmega2560.ICSP header for programming microcontroller Compatible with existing Arduino software libraries Compatible with the Ethernet and Motor Controller Shields.The Mega 2560 is an update to the Arduino Mega, which it replaces.Mega 2560 Arduino Compatible Board MEGA2560 R3 ATmega2560-16AU CH340G USB. The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). Flash, Processing, MaxMSP). This library is not official software, completely made on.Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g.The power source is selected automatically.External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The second one is a not connected pin, that is reserved for future purposes.Schematic, Reference Design & Pin MappingEAGLE files: arduino-mega2560_R3-reference-design.zipSchematic: arduino-mega2560_R3-schematic.pdfPin Mapping: PinMap2560 page Summary MicrocontrollerThe Arduino Mega can be powered via the USB connection or with an external power supply. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board.
Arduino Mega 2560 Install Process OfThe recommended range is 7 to 12 volts. If using more than 12V, the voltage regulator may overheat and damage the board. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.The board can operate on an external supply of 6 to 20 volts. Maximum current draw is 50 mA.The ATmega2560 has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library).Each of the 54 digital pins on the Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. A 3.3 volt supply generated by the on-board regulator. Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). This pin outputs a regulated 5V from the regulator on the board. You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip. Used to receive (RX) and transmit (TX) TTL serial data. Serial: 0 (RX) and 1 (TX) Serial 1: 19 (RX) and 18 (TX) Serial 2: 17 (RX) and 16 (TX) Serial 3: 15 (RX) and 14 (TX). In addition, some pins have specialized functions: Print a lot of slides on one page for macThe SPI pins are also broken out on the ICSP header, which is physically compatible with the Uno, Duemilanove and Diecimila. These pins support SPI communication using the SPI library. SPI: 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS). Provide 8-bit PWM output with the analogWrite() function. PWM: 2 to 13 and 44 to 46. See the attachInterrupt() function for details. Reference voltage for the analog inputs. By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and analogReference() function.There are a couple of other pins on the board: Note that these pins are not in the same location as the TWI pins on the Duemilanove or Diecimila.The Mega2560 has 16 analog inputs, each of which provide 10 bits of resolution (i.e. Support TWI communication using the Wire library. TWI: 20 (SDA) and 21 (SCL). When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. An ATmega16U2 ( ATmega 8U2 on the revision 1 and revision 2 boards) on the board channels one of these over USB and provides a virtual com port to software on the computer (Windows machines will need a. The ATmega2560 provides four hardware UARTs for TTL (5V) serial communication. Typically used to add a reset button to shields which block the one on the board.The Arduino Mega2560 has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. Bring this line LOW to reset the microcontroller. The Arduino software includes a Wire library to simplify use of the TWI bus see the documentation for details. The RX and TX LEDs on the board will flash when data is being transmitted via the ATmega8U2/ATmega16U2 chip and USB connection to the computer (but not for serial communication on pins 0 and 1).A SoftwareSerial library allows for serial communication on any of the Mega2560's digital pins.The ATmega2560 also supports TWI and SPI communication. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the board. It communicates using the original STK500 protocol ( reference, C header files).You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header see these instructions for details. For details, see the reference and tutorials.The ATmega2560 on the Arduino Mega comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer.
