I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work. We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features. More than that, we also develop the dedicated picture data convert software (bitmap converter)?now is available to support PC platform of windows, Linux, Mac OS. Through the bitmap convert software you can put your favorite picture displayed on I2C_LCD, without the need for complex programming.
