This is a C++ code snippet that appears to be a part of the Marlin firmware configuration file. It's used to configure various settings for an Arduino-based 3D printer controller, specifically for LCD displays, SD cards, encoders, and other peripherals. Here's a breakdown of the different sections: 1. **LCD LANGUAGE**: - This section allows you to choose the language extension installed on your controller. - You can set it to 'JAPANESE', 'WESTERN', or 'CYRILLIC' depending on your requirements. - To determine which language extension is installed, compile and upload with LCD_LANGUAGE set to 'test' and click the controller to view the LCD menu. 2. **LCD TYPE**: - This section enables support for character-based (16x2, 16x4, 20x2, or 20x4) or full graphical displays (128x64). - For character-based displays, use `#define ULTRA_LCD`. - For full graphical displays, use `#define DOGLCD`. This requires the U8glib library. 3. **SD CARD**: - SD Card support is disabled by default. If your controller has an SD slot, uncomment this option to enable it. 4. **SD CARD: SPI SPEED**: - This section allows you to choose a slower SPI transfer speed if required. - You can set it to `SPI_HALF_SPEED`, `SPI_QUARTER_SPEED`, or `SPI_EIGHTH_SPEED`. 5. **SD CARD: ENABLE CRC**: - Use this option to enable CRC checks and retries on the SD communication. 6. **ENCODER SETTINGS**: - This section allows you to override the default number of encoder pulses needed to produce one step. - You can set it to a higher value for high-resolution encoders. 7. **Encoder Direction Options**: - These options allow you to reverse the direction of your encoder or menu navigation. 8. **SPEAKER/BUZZER**: - This section enables support for a speaker that can produce tones. - By default, Marlin assumes you have a buzzer with a fixed frequency.
