在需要實時大量輸入漢字的顯示控制處理應用中,利用傳統單片機實現顯示控制的設計方法是較難實現的。帶漢字字庫的液晶模塊的使用使得小容量ROM單片機的大量漢字信息輸入與顯示成為可能。提出了針對漢字字庫編碼的二級索引拼音輸入檢索方法,介紹了以ST7920作為控制器的帶漢字字庫的液晶顯示模塊的接口方法及漢字顯示和控制原理,給出了通用計算機鍵盤在單片機中的串行接口,采用該技術可大大增強單片機的漢字輸入功能。為小容量ROM單片機的大批量漢字信息處理提供了一種漢字輸入解決方案。
Abstract:
It is difficult to realize Chinese characters input method based on the embedded system by using the traditional design method of display control. It is possible to input and display Chinese characters based on the embedded system with the ROM of small content by using the LCD module with Chinese characters.Chinese characters input method of the quadric index recall in allusion to Chinese characters code is brought forward.The interface and the principle of Chinese characters display control based on the LCD module controlled with the ST7920 is introduced too.The serial interface of the computer keyboard in common use and the embedded system is given at the same time. It can enhance the embedded system function of Chinese characters input by using this technology, and provide a kind of Chinese characters input scheme for the embedded system with small capacity ROM.
This is an example how one could hide a process on Windows based
operation systems from task viewers like ProcDump (G-RoM, Lorian
& Stone) or ProcessExplorer (SysInternals).
It could e.g. be used as some kind of dump protection.
The way to get this done is very different on NT and 9x machines.
The SL11RIDE is a low cost, high speed Universal Serial Bus RISC based Controller board. It contains a
16-bit RISC processor with built in SL11RIDE ROM to greatly reduce firmware development efforts. Its
serial flash EEPROM interface offers low cost storage for USB device configuration and customer product
specific functions. New functions can be programmed into the I2C by downloading it from a USB Host
PC. This unique architecture provides the ability to upgrade products, in the field, without changing the
peripheral hardware.
