本实验将实现如下功能：
1,通过STM32的USART2（PA2，PA3）连接ATK-HC05蓝牙模块,检测并显示蓝牙模块的状态.
2,通过KEY0按键可以开启/关闭定时向ATK-HC05蓝牙模块发送数据(ALIENTEK HC05 xx)测试蓝牙模块的数据发送.
3,可以通过WK_UP按键设置ATK-HC05蓝牙模块的主从工作模式.
4,可以通过LCD显示ATK-HC05蓝牙模块接收到的数据.
5,可以通过USMART对ATK-HC05蓝牙模块进行AT指令查询和设置.
6,结合手机端蓝牙软件(蓝牙串口助手v1.97.apk),可以实现手机无线控制开发板(点亮和关闭LED1).
The experiment will achieve the following functions: 1, through the STM32 USART2 (PA2, PA3) connection ATK-HC05 Bluetooth module, to detect and display the Bluetooth module state 2, by KEY0 keys to turn on/off timer sends ATK-HC05 Bluetooth module data (ALIENTEK HC05 xx) data test Bluetooth module is sent. 3, you can set the main ATK-HC05 Bluetooth module by WK_UP keys. 4, can display ATK-HC05 bluetooth module receives data the operating mode LCD. 5, can by USMART of ATK-HC05 Bluetooth module AT commands and settings. 6, combined with the Bluetooth mobile client software (Bluetooth serial assistant v1.97.apk), mobile wireless control can be realized development board (lights on and off LED1).

The Cantor expansion of the natural number x is
x = ak * k!+a(k − 1) *(k − 1)!+.... + a2 * 2!+a1*1!
where all the ai (digits) satisfy 0 ≤ ai ≤ i
it is easy to find a algorithm,we find the largest integer k that can satisfy 给一个正整数求出它的康拓展开
离散数学the definition first,then fix ak and substract ak * k from x,so we can fix ai ,0 ≤ i ≤ k

*********************************** 说 明 ***********************************
接收到的信号为发送信号的反码因为每检测到按键有效一次PT2262 都发送四次编码我们可以
利用这一特点来解码先检测有没有接收到信息当有的时候我们就去掉第一次编码的信号检测5ms 的
高电平来检测编码的开始信号接收到5ms 的高电平后才开始解码我们可以发现每个码的长度都是1.2ms
左右每一个编码都是由低电平开始然后到高电平又到低电平又回到高电平我们从第一个高电平
的宽度可以把1 码区分出来剩下的悬空码和0 码可以从第二个高电平的宽度区分出来
具体的单片机译码方法如下
由高电平开始检测到下降沿时就延时300us 读取接收的状态记为A0 然后再检测下一个下降沿
降沿后又延时300us 读取接收的状态记为A1 这样就把一个编码给译出来了
A0 A1 和悬空1 码0 码的关系如下:
A0 A1 代码
0 0 1 码
0 1 错误
1 0 悬空
1 1 0 码
