Abstract
The main body of a book has been explained mainly adopt 1602 characters type liquid crystal display module to carry out liquid crystal display, the basic having set forth liquid crystal display designs a technology.
The process entire design is developed arranges the main body of a book ready-made archives unfolding to reader.
It suggests that from the preface , problem , the analysis liquid crystal display has been carried out one by one tier throughly such as need analysis , feasibility study , operating principle , detailed design studies, which have introduced the visit way how to wield 89 C51 monolithic machine and 1602 liquid crystal displays module directness very good, realize the entire proceeding of liquid crystal display thereby.
The liquid crystal display module is by certain 5*8 lattice block composition demonstration character group；Have 80 bytes RAM ；Every lattice piece is a character place, both character spacing and space be a width.
This design manufacture will realize certain character quantity demonstration through the hardware and the software union；And, may part for under the button effect, makes the person begin to demonstrate and end display。
You will show time a function having a more limpid cognition , the reader who will also be that possessions feels interest and the subclass technology gives certain help.
Have the insufficient place to hope that you suggest that much, and the general corrects in time!
