BCH码的二进制FEC码的译码

该代码为配合7号信令模块MK50H27的cpld(xilinx 95144)的逻辑代码,其中包括了VHDL及原理图.-the code to meet on the 7th of signaling modules MK50H27 cpld (Xilinx 95144 ) logic code, which included a schematic and VHDL.

说明：  按键消抖,避免按键抖动造成信号误触发，增大按键输入的可靠性(Key jitter elimination, avoid key jitter caused by signal error trigger, increase the reliability of key input)

FPGA开发超声波测距，可改写工业探伤或倒车测距等系统，quartus2下选择EP2C5Q208C8（CycloneⅡ） 支持目前淘宝上能买到的所有4-5针超声波模块 应用cycloneⅡ自带除法模块 开发板为有光技术YG2.1 生成电路规模较小 ！！注意：移植程序仅需重新约束数码管和超声波模块的针脚 (Ultrasonic Ranging FPGA development, industrial inspection or reverse rewritable ranging systems, EP2C5Q208C8 (CycloneⅡ) under quartus2 4-5 needle ultrasonic module supports all currently scouring the treasure can buy Applications cycloneⅡ own division module Development board bright technical YG2.1 Small scale generating circuit ! ! Note: The migration program only re-constraint digital and ultrasonic modules Pin)
