Development_Notes
说明： 设计功能：
1.实现通过按键中断来控制LED的循环闪烁，分为3种速度循环闪烁。 2.实现定时器的相关功能和PWM信号的生成，当按键中断到来时，实现在开发板的GPIO口改变PWM信号的占空比，以此PWM信号控制电机的运转速度。 3.实现通过虚拟串口发送当前电机信息的功能，每当按下按键后，开发板将电机的转速等级和此时控制电机的占空比通过串口发送到计算机的串口程序中。(Designing function:
1. To control the cyclic flicker of LED by interruption of keys, it can be divided into three kinds of speed cyclic flicker. 2. Realize the function of timer and the generation of PWM signal. When the key interrupt arrives, the duty cycle of PWM signal is changed at the GPIO port of the development board to control the speed of motor. 3. Realize the function of sending the current motor information through the virtual serial port. Whenever the key is pressed, the development board sends the speed level of the motor and the duty cycle of the control motor through the serial port to the serial port program of the computer.)

TMS28335初始化完成之后，
1、 先DDS产生73.35hz的方波。（问流量管固定频率）
2、 乘法器的另一个数字端输入乘数直接给一个固定值（按照5v），系数是固定的就是对应PID输出的那个接口，串行十二位信号输出（需要先定好一个GPIO接口）。
3、 再延迟一定的时间0.1s或其他时间之后，开始ad采集信号，分别采两路AD信号，此时不稳定（为什么要等到一定的幅值才开始采集AD信号）
4、 选择250点估计一个频率，频率估计的方法采用计算峰值次数的方法或者过零点，总之是为了保证精度采用时域估计的算法，这一块主要是一个扫频子程序，计算频率共振点。
5、 之后改变DDS的输出频率，循环对512点的数据进行扫频的处理
6、 频率控制完成之后，就可以缓慢降低PID控制输出的参数，此时暂时不计算频率，通过不断调整系数使AB的幅度保持在1 的范围内。
7、 测试幅度控制稳定之后a、采用幅度和频率同时控制b。采集数据进入频率估计和相位差估计的后续程序的大循环
8、 注意：采样和控制是同时进行的，所以要设置中断，以及看懂AD的程序，以及内部存储以及数据处理资源的分配。
(TMS28335 initialization is complete,
1, the first DDS generated square wave of 73.35hz. (Q flow tube fixed frequency)
2, another digital side of the multiplier input multiplier directly to a fixed value (in accordance with 5v), the coefficient is fixed corresponding PID output interface, serial twelve signal output (need to be a good one GPIO interface).
3, and then after a certain time delay 0.1s or other time, ad signal acquisition were collected two AD signal instability (Why wait until a certain amplitude began collecting AD signal)
4, 250 point estimate a frequency, frequency estimation method using the method of calculation of the number of peak or zero crossing, in short, in order to ensure the accuracy of time-domain estimation algorithm, this piece is a sweep subroutine to calculate the frequency resonance point.
5, after the change of the output frequency of the DDS data of 512 points, the loop processing Sweep
6, after the completion of the frequency control, it can sl)
