The integration of the PIC24F DA family enables next generation graphics and modern user interface features. Here is one example of how this integration would benefit a real embedded application such as this thermostat. As shown in the system block diagram, the thermostat application takes advantage of features available on the PIC24 DA family. Besides utilizing the graphics acceleration units and display controller to drive nice a graphics display on the 3.5” TFT, the application also uses the capacitive touch sensing to implement sealed buttons and keys. The integrated USB enables users to customize display colors and themes, and provide data logging capability. The SPI communication is also available if RF or wireless features need to be added.
