该设备是一款基于AVR mega16L单片机的电子书阅读器，它除具有传统的阅读电子资源功能外，还能通过PS2接口与PC键盘连接，使用普通PC键盘输入信息，进行文本录入；使用LCD12864液晶作为显示器，它还可以用VB专门为之编写的下载软件通过串口下载TXT格式的文本资源。电子书资源存储在AVR公司生产的AT45DB021B闪速存储器，它有2M存储空间，可满足一般用户需要，当然也可升级为大容量存储器。 该设备功能强大，将电子书阅读器发挥到了极致，能满足用户特殊需要。 -The device is a single chip based on the AVR mega16L e-book reader, which in addition to the traditional functions of reading electronic resources, but also through the PS2 interface to connect with the PC keyboard, use an ordinary PC keyboard input information, the text input use LCD12864 LCD as a display, it can be prepared by specialized VB download software through the serial port to download TXT format text resources. E-book resources are stored in the AVR produced AT45DB021B flash memory, it has 2M storage space to meet the needs of general users, of course, can also be upgraded to a large-capacity memory. The device is powerful and will play an eBook reader to the extreme, and to meet the special needs of users.
