# lcd1602 Library This library provides support for the LCD1602 and LCD2004 devices connected to an i2c master device via a PCF8574 serial-to-parallel converter chip. This library currently supports the following platforms: * Linux i2c subsystem * esp-idf # Usage ## API The API for this library can be found in the `include/lcd1602.h` header file. ## Portability Portability among various host platforms (e.g. Linux i2c device interface vs. the esp-idf i2c driver interface) is accomplished via a platform-specific `lcd1602_lowlevel_config` structure which is defined at compile-time for the project based on build environment and/or toolchain hints. An example configuration for `lcd1602_lowlevel_config` for Linux is: ```bash lcd1602_lowlevel_config config; config.device = "/dev/i2c-0"; ``` An example configuration for `lcd1602_lowlevel_config` for esp-idf is: ```bash lcd1602_lowlevel_config config; config.port = I2C_NUM_0; config.pin_sda = GPIO_NUM_21; config.pin_scl = GPIO_NUM_22; ``` Note that the members of the `lcd1602_lowlevel_config` change (at compile-time) based on the target platform. # Example Applications Example applications are provided for each of the supported platforms. # License All files delivered with this library are copyright 2024 Zorxx Software and released under the MIT license.
