ARM-based serial communications (dynamic display of digital control) Abstract: As technology continues to develop, people's demand for a better processor, continuously moving in a variety of micro-processors, intelligent, integrated development, the appearance of the development of ARM eighties to the present, has gradually replaced the original MCU market share to about 90 percent, as the technology matures, its cost decreased, I believe the future will increase its market share. So their study will be important. This design of the serial communication hardware and software are mainly two parts, hardware, including the LM3S1138 development board, decoder, digital tubes. Digital control can display the data and methods we want, can also be keys to change the digital tube display, upon request, conditions can change the interrupt, this simple to learn ARM serial communication on future learning and development will help promote role in the learning and application to lay the necessary foundation.
