![]() The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be activated by: The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository. ![]() 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. The Mega 2560 board can be programmed with the Arduino Software (IDE). Arduino Mega Pinout Diagram: ardunio mega pinout Arduino Mega Specifications: MicrocontrollerĪrduino Mega 2560 is open-source hardware! You can build your own board using the follwing files:ĮAGLE FILES IN. The Mega is compatible with most shields designed for the Arduino 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 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 is a microcontroller board based on the ATmega1280 (datasheet).

The ATmega1280 and ATmega2560 have four pins that have this feature, but none of them are connected to Arduino headers! Evidentally, the designers of the Arduino Mega did not think anyone would be interested in using the input capture feature of the ATmega microcontrollers. Evidently, the designers of the Arduino Mega did not think anyone would be interested in comparing analog voltages.Īlso, overlaying text and graphics on a video image requires the use of an input capture pin so that we can know precisely when the beginning of a video line begins. The analog comparator pin AIN0 on the ATmega1280/ATmega2560 is not connected to any Arduino Mega pin! This is pin 4 on the ATmega1280/ATmega2560 and as you can see in the schematic, it is not connected. These features are connected to different pins on the Arduino Mega or not connected at all. The Video Experimenter depends on ATmega features like input capture, external interrupt detection, and the analog comparator. Many of the pin assignments on the Arduino Mega are different than the pin assignments on the Arduino Uno/Duemilanove/Diecimila.
