The GLT12232A-SM is an intelligent graphic liquid crystal display engineered to quickly and easily add an elegant creativity to any application. In addition to the RS232, TTL, and I2C protocols available in the standard model, the USB communication model allows the GLT12232A-SM-USB to be connected to a wide variety of host controllers. Communication speeds of up to 115.2 kbps in serial modes and 400 kHz in I2C ensure lightning fast text and graphic updates.
The simple command structure permits easy software control of many settings including backlight brightness, screen contrast, and baud rate. On board memory provides a whopping 256KB of customizable fonts and bitmaps to enhance the graphical user experience.
User input is available through a resistive touch overlay. In addition, two general purpose outputs provide simple switchable five volt sources on each model, while a small piezo speaker offers audio feedback for a completely interactive experience.
