Custom characters are mapped to values 0-7.Ĭol (uint8_t): the character to write to the display Row (uint8_t): row, Arduino format (0-3) write(data) Pos (uint8_t): cursor position (0-79) setCursor(col, row)Ĭol (uint8_t): column, Arduino format (0-19)

Rows (uint8_t): the number of display rows clear()Ĭlear the display and return the cursor to the top-left. Initialise the display of size cols * rows, clear the display and set the cursor to the top-left.Ĭols (uint8_t): the number of display columns I2c_scl (uint8_t): the clock (SCL) line pin for I2C (ESP8266 only, optional, defaults to setting SCL from Wire.h) begin(cols, rows) I2c_sda (uint8_t): the data (SDA) line pin for I2C (ESP8266 only, optional, defaults to setting SDA from Wire.h) I2c_address (char): 8-bit I2C address of the display (optional, as displayed during LCD initilisation) On ESP8266 architectures only, i2c_sda and i2c_scl can optionally be used to set the data (SDA) and clock (SCL) pins used for I2C. If i2c_address is omitted the LCD03’s default I2C address (0xC6) is used. The following public functions are exposed. You’ll need to restart the Arduino IDE after installing before the library will be detected. zip of the repository and unzip it to a directory named ‘LCD03’ in your Arduino libraries directory. To install without git, simple use the “ZIP” link from the GitHub page to grab a. $ git clone git:///andatche/arduino-lcd03.git LCD03 Simply navigate to your Arduino libraries directory and clone the git repository into a directory named ‘LCD03’. The latest stable release is version 1.1.2 (zip) (tar.gz) (browse). The library is released under the GNU LGPL 2.1.įor source, issues or to contribute, please see the project page on GitHub. Supports Arudino 1.0.0 and newer on avr and ESP8266 architectures. It supports all features of the LCD03 including custom characters and the ability to read the keypad. It aims to maintain compatibility with the Arduino LiquidCrystal library (version 0017 onwards), though some features of LiquidCrystal are ommited and additonal features are provided. LCD03 is an Arduino library for I2C control of the LCD03 20x4 and 16x2 serial LCD modules from Robot Electronics, see the datasheet for details.
