实现stm32任意八个io定义矩阵键盘 KGPT KPIN={ //只需要在下面填写横竖行的IO口和管脚 IO口和管脚都可以随意定义 无需在一个IO口 管脚也无需按顺序 {{GPIOG,GPIO_Pin_4} ,{GPIOG,GPIO_Pin_2}, {GPIOD,GPIO_Pin_14},{GPIOD,GPIO_Pin_12}},//row 横行 {{GPIOD,GPIO_Pin_10},{GPIOD,GPIO_Pin_8}, {GPIOB,GPIO_Pin_14},{GPIOB,GPIO_Pin_12}} //col 竖行 };(realise the matrix_bored_pad of 4*4)

有2*n个盒子排成一行，其中有两个相邻的空盒，有n-1个盒子有符号 A ，有n-1个盒子有符号 B 。例如，n=5，并有初始配置如下： A B B A . . A B A B (2* n box row, wherein there are two adjacent empty box, n-1 of a box with the symbol ' A' , the symbol ' B' n-1 th box. For example, n = 5, and the initial configuration is as follows: ABBA .. ABAB)
