Arduino Mega 2560 Rev3 Pinout, Atmega2560 Pin Mapping, EAGLE Files. Pin Mapping refers to the relationship between assigned “pin numbers” and the actual hardware ports on the CPU. Marlin uses FastIO macros whenever possible because direct port manipulation is many times faster than the pin functions provided by Arduino.h. FastIO and Pin MappingįastIO is a set of macros that allows Marlin to read and write pins quickly, using the same code on all processors. See the boards list below for a complete list of boards supported in the latest release of Marlin. This example selects a RAMPS 1.4 board with the 12V power MOSFET connectors arranged in Extruder, Fan, Bed (EFB) order: 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. To build Marlin for a specific board, set the MOTHERBOARD option in Configuration.h. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Some boards will need a new PlatformIO environment with custom build settings. Some of these files are shared by related boards.Īuto-assign stepper and endstop pins for extra axes. See Board Pins for more details.Įach of these files assigns pins to Marlin functions. Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of. Arduino Mega or Mega 2560 ATmega2560 (Mega. Includes the appropriate pins_BOARD.h file for the specified MOTHERBOARD. CHIPS Alliance Espressif 32 Espressif 8266 Freescale Kinetis Heltec. Set MOTHERBOARD to one of the boards listed here. Several files in the Marlin source code provide hardware support, but the files supporting the core electronics are: FileĬontains the full list of boards supported by Marlin. The Hardware Abstraction Layer created for Marlin 2.0 provides a consistent set of interfaces, making it much easier to add support for new platforms. Originally Marlin was designed to run on low-powered 8-bit AVR boards, but starting with Marlin 1.1.9 it has gained support for dozens of ARM-based boards. Marlin supports a wide variety of 3D printers, including all RAMPS variants, and is adaptable to virtually any Arduino/Genuino-based electronics through pin-mapping - associating pins with their functions. ![]()
