51和迪文串口屏通信C语言源码，温度采集显示，可以进行移植，很友好，很详细，附带的例程帮助很大(51 and Devon serial port communication C language source code, temperature acquisition display, you can transplant, very friendly, very detailed, with the help of a large routine.)

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.
