E-book reader
Books are an important way for us to acquire knowledge.
The invention of words gave us a culture.
The inheritance of culture has made us what we are today.
Books, as a means of dissemination of cultural knowledge. Nowadays, with the development of science and technology, there have been different changes.
In ancient times, the leaders of the group showed to posterity what happened at that time by carving on the stone.
Later, it was carved on trees and sheepskins. But how heavy and inconvenient it is.
The invention of paper is one of the great inventions of mankind.
With the continuous advancement of technology, in order to facilitate our reading and reduce myopia, e-book readers have appeared.
In 2007, Amazon launched the Kindle, an e-book reader, which swept the world for a while.
The control system based on the microcontroller of the STM32103 series of integrated circuits can better provide the standby time of the e-book reader, provide larger memory, and provide more functions.
