HDLC控制器

基于FPGA的出租车计价器，欢迎大死同学多多交流(FPGA-based Taximeter, welcomes the dead students more exchanges)

control stepper motor by fpga card with vhdl program

实现了UART的底层协议，加入了控制器，其波特率可以根据使用进行调整；发送模块、接收模块相互独立，互不影响。(Realization of the underlying protocol UART, joined the controller baud rate can be adjusted according to use transmission module, receiver module are independent of each other.)

控制三相步进电机及光电编码器的采集,当电机停止时,保证三相里面只有一相相通,防止停止时电流过大.(Control three-phase stepper motor and optical encoder collection, when the motor stops to ensure that only one phase of three-phase inside the heart, and to prevent too much current is stopped.)

用游戏把子上下左右控制蛇的方向，寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度就越大，不能碰墙，不能咬到自己的身体，更不能咬自己的尾巴，等到了一定的分数，就能过关，然后继续玩下一关。

说明：  半带滤波器，用于sigma-delta DAC中的设计(Half-band filter for sigma-delta DAC design)

说明：  基于FPGA设计的串口发送及接收程序，波特率可调(FPGA - based serial port sending and receiving)
