The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository.
#2560 pinout serial
You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar see these instructions for details. It communicates using the original STK500 protocol ( reference, C header files). The ATmega2560 on the Mega 2560 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. For details, see the reference and tutorials.
#2560 pinout software
The Mega 2560 board can be programmed with the Arduino Software (IDE). You can find here your board warranty information. Need any help with your board please get in touch with the official Arduino User Support as explained in our Contact Us page.

#2560 pinout update
The Mega 2560 is an update to the Arduino Mega, which it replaces. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila. 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 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. Typically used to add a reset button to shields which block the one on the board.The Arduino Mega 2560 is a microcontroller board based on the ATmega2560.
Bring this line LOW to reset the microcontroller. There are a couple of other pins on the board:ĪREF. 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. The Mega2560 has 16 analog inputs, each of which provide 10 bits of resolution (i.e. Note that these pins are not in the same location as the TWI pins on the Duemilanove or Diecimila. Support TWI communication using the Wire library. When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off. There is a built-in LED connected to digital pin 13. The 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. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.Įxternal Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions: Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
