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.
