digital

一个数字梯形，选择k条路线，每条路线从第一层的某个数开始，每次进入下一层到达左下或者右下的数字，直到最后一层为止。每条路线不能经过相同的路径，但是可以经过相同的数字节点。 输出一个整数，表示能得到的最大的k条路径经过的数字之和(A digital ladder, the K route, each route the first layer of a number, each time to enter the next layer to reach the left or right next to the number, until the final layer. Each route can not pass through the same path, but can pass through the same number of nodes. Output an integer representing the sum of the number of the largest K paths that can be obtained)

三星94c8芯片写的线控器显示屏，TM1640，模拟串口(Samsung 94 written c8 chip line controller display, TM1640, simulate the serial port)

基于AVR单片机的挖掘机器人控制系统设计( Based on AVR monolithic integrated circuit s excavation robot control system design )

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)
