在生物信息学中，计算蛋白质-RNA生物网络中的长程相互作用(In bioinformatics, long range interactions in protein -RNA biological networks are calculated.)

本设计以TMS320F28027 DSP为主控制器，以产生占空比可调的PWM波，并采用PID控制调节直流电机的转速，用H桥作为功率驱动电路，使其在给定不同的转速时，电机能跟上转速要求。在电路板中，设置四个按键，来实现电机的启动、停止、正转、反转、加速以及减速的功能。同时，外接虚拟示波器，以显示电机当前的设定转速、实际转速以及电枢电流大小。(The design to TMS320F28027 DSP-based controller to generate a PWM duty cycle adjustable, and the use of PID control to adjust the DC motor speed, with H-bridge as the power drive circuit, so that given a different speed, the motor Can keep up with speed requirements. In the circuit board, set four buttons to achieve the motor start, stop, forward, reverse, acceleration and deceleration functions. At the same time, an external virtual oscilloscope to display the motor current set speed, the actual speed and armature current size.)

三相六拍直流无刷电机驱动固件，采用的TI的方案，已经用在我们公司的无刷圆锯上面了。特共享出来换积分(This is the driver for BLDC motor ,this firmware has been used on our BLDC product.)

BUCK电路闭环实现PI控制，输入电压或负载变化时保持输出电压不变(BUCK circuit closed loop to achieve PI control, input voltage or load changes, keep the output voltage unchanged)

用DSP实现的交通灯程序，希望相互学习，(Using DSP to achieve program the traffic lights, I hope to learn from each other,)

源信号数目的估计在阵列信号处理中有很广的研究了，这个源程序是基于新一代通信环境下的源信号数目估计，如mimo——ofdm(detection the number of source signals for MIMO_OFDM)
