Tools

LCDLAB is a free PC-based software tool to aid developing graphical user interfaces for the LCD64 family of displays. LCDLAB provides a means of programming images and text to the LCD6402 so they may be easily reproduced on the graphic LCD.

Typically, a number of graphic objects are prepared using LCDLAB where each object consists of images and text. These 'objects' are then compiled to binary and programmed to the LCD6402 via a serial programming lead. Once programmed the graphic objects are recalled by the user's host MPU via the I2C bus.

With LCDLAB comes Font Maker, a powerful tool for capturing and editing fonts which can be used in your LCD6402 application.
