They provide pretty complete descriptions of each option, and are themselves the source for most of the information presented here. The most authoritative source on configuration details will always be the configuration files themselves. 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. Most settings will come over without changes, then you can review any tricky changes that remain. 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. To migrate your settings to a new Configuration you can use tools like Notepad++ or Winmerge to compare old configurations with the newer (default) configurations and copy settings over on a change-by-change basis. As part of the build process, Marlin will check for outdated options and show error messages that explain exactly what needs to be changed.

To use configurations from an earlier version of Marlin, first try dropping them into the newer Marlin, updating CONFIGURATION_H_VERSION and CONFIGURATION_ADV_H_VERSION, and building the firmware. #define THIS_IS_DISABLED // this switch is disabled #define OPTION_VALUE 22 // this setting is '22' #define THIS_IS_ENABLED // this switch is enabled Settings can be enabled, disabled, and assigned values using C preprocessor syntax like so: A build of Marlin can range from 50K to over 230K in size.

This allows Marlin to leverage the C++ preprocessor and include only the code and data needed for the enabled options. Hi guys, what is the maximum voltage that i can input to arduino mega 2560 Digital Pins is it 5 volts or can i input 12 volts without damaging the board thank you in advance. Marlin is configured using C++ compiler directives. Hundreds of user-donated configurations are posted at the Configurations repository to get you started. Simply edit or replace these files, then build and upload Marlin to the board. h files contain all of Marlin’s build-time configuration options. See the Configuration with INI page for more information.

config.ini may be included to modify the configuration at the start of a PlatformIO build.

Configuration_adv.h contains more detailed customization options, add-ons, experimental features, and other esoteric settings.Configuration.h contains the core settings for the hardware, language and controller selection, and settings for the most common features and components.Marlin is a huge C++ program composed of many files, but among the most important are the files that contain all of Marlin’s compile-time configuration options:
