3C90X驱动源码，应用于嵌入式操作系统。可以使用。--Source code of the driver for 3C90X. It could be used in embedded operating systems.

应用背景使用c8051f020单片机做主机，控制led屏显示芯片带动led发光二级管，使用扫描方式可显示文字 字母等，关键技术由于c8051f020单片机的频率高，做主控制器可做到led亮度可调，无闪烁，稳定性好。本程序是32x24点阵的led模块，可以扩展。

该程序主要运用查询方式和中断方式两种方式进行键盘键值的获取，并显示在六个数码管上，显示的原则是最后按下的键值放在最低位的数码管上，其次的依次排列。-The main use of the program and the interruption of the way query in two ways to access the keyboard keys, and display in six digits, the principle is shown in the last key pressed on the lowest digital tube, followed by the sequence order.
