An ATmega16U2 ATmega 8U2 on the revision 1 and revision 2 boards on 2560 board channels one of these over USB and provides a virtual com port to software on the computer Windows machines will need a. The Arduino board has a number of facilities for communicating with a computer, another board, or other Mega. There are a couple of other pins on the board. By default they measure from ground to 5 volts, though is it possible to change the upper end Pinout their range Arduino the AREF pin and analogReference function. The Mega has 16 analog inputs, each of which provide 10 bits of Mega i.

Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor disconnected by default of k ohm.Ī maximum of 40mA Pinout the value that must not be exceeded to avoid Pdf damage to the microcontroller. Each of the 54 digital pins on the Mega can be used as an input or output, using pinModedigitalWriteand digitalRead functions. 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 2560 than five volts and the board may become unstable. The board can operate on an external supply of 6 to Mega volts. The adapter can be connected by plugging a 2. The power source is selected automatically. The Mega can be powered Pdf the USB connection or with an Arduino power supply. If more Pdf mA is applied to the USB port, the fuse Pinout automatically break the connection until the short or overload is removed. Although most computers provide their own internal protection, the fuse Arduino an extra layer of protection.

The ATmega16U2 or 8U2 in the rev1 and rev2 boards firmware source code is available in the Arduino repository. It communicates using the original STK protocol MegaC header files. The ATmega on Pinout Mega comes preprogrammed with a bootloader that allows you to upload new code to it without 2560 use of an external hardware programmer. Arduino - PinMappingįor details, see the reference and tutorials. Arduino Arduino is open-source hardware! You can build your Pinout board using the follwing files. 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 2560 or Mega it with Pdf AC-to-DC adapter or battery to get started. *out |= bit // set the bit e.g.The Arduino Mega is a microcontroller board based on the ATmega datasheet. SREG = oldSREG // restore state register (enable interrupts) Set the Arduino pin 13 as output (equivalent to pinMode(13,OUTPUT)) DDRB |= 1 0101 You don't need to care about MCUCR, unless you want to disable pull-up on all pins. Port B and bit 7.īit 7 in DDR B controls the direction (input/output)īit 7 in PORT B controls the output (high/low) You can find which Arduino pin is connected to which ATMega pin in schematic.Įxample: Controlling Arduino pin 13 find the port and bit for Arduino pin 13īy looking at the pinout map above, you will find "PB7" next to pin 13.Īrduino pin 13 is connected to ATMega2560 pin P B7 on the Arduino circuit board. The pinout map above is derived from the schematic. Look at the schematic for Arduino Mega and the ATMega2560 Datasheet The tan box in the pinout map below shows the pin name assigned by Atmel (who makes the chip). To toggle a given Arduino pin, you will need the x (port) and n (bit) to locate the registers and bits. “x” represents the numbering letter for the port, and “n” represents the bit number.įinding the registers for a given Arduino pin PUD in MCUCR disables all pull-up resistors if it is set to 1. PORTxn bit in PORTx register controls the output (high/low digitalWrite()) Three bits in three registers control the state of a GPIO pin:ĭDxn bit in DDRx register controls the direction (input/output pinMode())
