51单片机PID算法

可靠的串口stm32串口程序，注意，这不是简单的例程，而是具有实用价值的程序，将printf函数进行了重载，并且不会造成内存泄露，另外还有一个完全自己写的printf函数，两个函数都可以使用，至于选择哪个程序用，则是仁者见仁智者见智的事了。

FPGA DE2开发板  实验2第一部分VHDL硬件语言练习源码 Part II You are to design a circuit that converts a four-bit binary number V = v3v2v1v0 into its two-digit decimal equivalent D = d1d0. Table 1 shows the required output values. A partial design of this circuit is given in Figure 1. It includes a comparator that checks when the value of V is greater than 9, and uses the output of this comparator in the control of the 7-segment displays. You are to complete the design of this circuit by creating a VHDL entity which includes the comparator, multiplexers, and circuit A (d
