关于介绍AVR单片机指令的一本书，挺不错的，在开发单片机上方便查询-AVR on the introduction of a single-chip instruction book, very good, in the development of single-chip to facilitate query

用winband78e58 对422通讯操作，422通讯作为工业常用的串行通讯协议，使用广泛-with winband78e58 communications operation of 422, 422 communications industry as a common serial communication protocol, widely used

SPI是一个环形总线结构，由ss（cs）、sck、sdi、sdo构成，其时序其实很简单，主要是在sck的控制下，两个双向移位寄存器进行数据交换。 假设下面的8位寄存器装的是待发送的数据10101010，上升沿发送、下降沿接收、高位先发送。 那么第一个上升沿来的时候 数据将会是sdo=1；寄存器=0101010x。下降沿到来的时候，sdi上的电平将所存到寄存器中去，那么这时寄存器=0101010sdi，这样在8个时钟脉冲以后，两个寄存器的内容互相交换一次。这样就完成里一个spi时序。 -SPI bus is a ring structure, by ss (cs), sck, sdi, sdo composition, its timing is actually very simple, mainly under the control of the sck and two bi-directional shift register for data exchange. Assuming the following 8-bit register is loaded to send the data to be 10,101,010, rising to send, receive falling edge, high first sent. Well, the first rising edge to the time data will be sdo = 1 register = 0101010x. Falling edge comes, sdi on the level will be stored to the register, then register at this time = 0101010sdi, so 8 clock pulse later, the contents of two registers to exchange time. This will be completed in a spi timing.

AVR单片机，mega16开发板，一些小程序，裸捐了。-AVR single-chip, mega16 development board, a number of small procedures, nude donated.

AVR脉宽调整的程序，还可以！具有借鉴的价值！-AVR width adjustment procedures, but also! With reference value!

这是单片机MS-51双字节带符号数除法扩展子程序-This MS-51 with two-bit symbols divider expansion subroutine! !

三。对于进入密码锁的钥匙，假设复位后8个LED全亮，并使用sw1、sw2、sw3 3，然后sw2-> sw1-> sw3-> sw1，则表示解锁右侧会导致8个LED全暗。

There a lot of program can be used it is wonderful

AT98S52单片机头文件，可直接对IO口进行位操作，简单方便-AT98S52 Singlechip header files can be directly carried out the mouth of the IO-bit operation, simple and convenient
