+初始化键盘矩阵
+@api keyboard.init(port, conf, map, debounce)
+@int 预留, 当前填0
+@int 启用的keyboard管脚掩码, 例如使用keyboard0~9, 则掩码为 0x1FF, 若使用 0~3 则 0xF
+@int keyboard管脚方向映射, 其中输入为0,输出为1, 按位设置.  例如 keyboard0~3作为输入, keyboard4~7为输入, 则 0xF0
+@int 消抖配置,预留,可以不填
+@usage
+-- 做一个 4*4 键盘矩阵, 使用 keyboard0~7, 其中0~3做输入, 4~7做输出
+-- 使用 keyboard0~7, 对应conf为 0xFF
+-- 其中0~3做输入, 4~7做输出, 对应map 为 0xF0
+keyboard.init(0, 0xFF, 0xF0)
+
+-- 做一个 2*3 键盘矩阵, 使用 keyboard0~4, 其中0~1做输入, 2~4做输出
+-- 使用 keyboard0~4, 二进制为 11111,  对应conf的十六进制表达为 0x1F
+-- 其中0~1做输入, 2~4做输出, 二进制为 11100 对应map 为 0x14
+-- keyboard.init(0, 0xFF, 0x14)
