Graphic-enabled devices are used extensively in daily
life. They are found everywhere, including indoor
products, such as telephones, calculators, pagers, MP3
players, digital electric meters, smart remote and UPS
displays. They are also used in outdoor products, such
as traffic signals, taxi meters, bus displays, advertisement
boards, etc. The list is virtually endless. A current
trend is that many existing devices are becoming
graphic-enabled because it is economically feasible,
easy to use and the latest in technology.
This application note is intended to help engineers who
are designing their first graphic application. It describes
the basic definitions and jargons of graphics applications
and it helps the engineer to understand the theory,
necessary decision factors, hardware considerations,
available microcontrollers and development tools. Software
libraries and support are available from Microchip
with further literature references for advanced users.
