This product has been designed to simplify the implementation of TFT technology into your product. The high level text based object oriented command structure, entity library and 100 page screen memory allow most of the processing to be undertaken by the TFT module leaving the host CPU to concentrate on the core application processes. This allows proven firmware running on small 8 bit microcontrollers to be modified to drive this TFT module with a minimum of work and risk.
