By consider the bugs and solutions found about the graphics processor and 4GDL compiler, we deside to use the state machine to implement the final version of the display module.
The statement machine is to make every screen as a state and command input as the conditation for the state change. As recently there is a demo in Japan, I implement a simple state machine code which has less screen. It has been sent to Japan for the testing and it works fine. In addition, I am starting to finish implement the final version, which put all the display screen into the state machine for the final implementation of the display.
