RDA SINGLE CHIP FOR BLUETOOTH datasheet v1.42EN

改c程序基于stm32，开发环境是keil4.7，利用stm32的高级定时器TM1产生4路两两互补的SPWM波，分别去驱动H桥的四个桥臂，死区可通过程序自行设定，改程序利用查表法，一个正弦周期采样256个点，输出8位精度的spwm波。自带稳压程序，离散pid。输出波形较好。

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
