用keil c语言介绍8051单片机开发一本书 很不容易才找到的啊！-language used Keil 8051 development on a book not easy to find the ah!

USBASP的源程序，里面有和USB通讯的例子-USBASP the source, there are examples and USB communications

4*4矩阵键盘（行扫描法） （S51环境）-4* 4 matrix keyboard (line scanning) (S51 environment)

此为18B20的驱动程序,经过实验,是可行的-18B20 This is the driver, after experiment, it is feasible

C51源程序库（二十多个）-C51 source library (over 20)

16*16点阵的，觉得这个里面用 指针来查找数组蛮好的 。-16* 16 lattice, and find this inside with fine pointer to the search array.

ADC0809是广泛使用的模／数转换器，在可不采用外部总线结构的单片机系统中(如 由AT89C51组成的系统)。ASC0809的数据线直接与单片结构的I／0 口相连，并由单片机的I／O 口直接对ADC0809进行控制。-ADC0809 is widely used in analog/digital converters, in not using the external bus architecture in the single-chip microcomputer system (such as the composition of the system by the AT89C51). ASC0809 data lines directly with the monolithic structure of I/0 I connected the MCU I/O port directly to control the ADC0809.
