[SCM] bianmakaiguan DL : 0: 本代码为编码开关代码，编码开关也就是数字音响中的 360度旋转的数字音量以及显示器上用的（单键飞梭开关）等类似鼠标滚轮的手动计数输入设备。我使用的编码开关为5个引脚的，其中2个引脚为按下转轮开关（也就相当于鼠标中键）。另外3个引脚用来检测旋转方向以及旋转步数的检测端。引脚分别为a,b,c b接地a，c分别接到P2.0和P2.1口并分别接两个10K上拉电阻，并且a，c需要分别对地接一个104的电容，否则因为编码开关的触点抖动会引起轻微误动作。本程序不使用定时器，不占用中断，不使用延时代码，并对每个细分步数进行判断，避免一切误动作，性能超级稳定。我使用的编码器是APLS的EC11B可以参照附件的时序图编码器控制流水灯最能说明问题，下面是以一段流水灯来演示。-Code for encoding the switch code, coding switch is in the digital audio The number of 360-degree rotating display with the volume, as well as the (one-touch open Shuttle Clearance) and similar to manually count the mouse wheel input device.

[SCM] jianpan24 DL : 0: 24键键盘程序，引脚说明及连线列线：p4.0 p4.1 p4.2 p4.3 作为输入行线：p4.4 p4.5 p4.6 p4.7 p6.5 p6.6作为输出 1、检测当前是否有键被按下。检测的方法是P4.4-P4.7,P6.5,P6.6输出全"0"，读取P4.0-P4.3的状态，若P4.0-P4.3为全"1"，则无键闭合，否则有键闭合。 2、去除键抖动。当检测到有键按下后，延时一段时间再做下一步的检测判断。 3、若有键被按下，应识别出是哪一个键闭合。方法是对键盘的行线进行扫描。P4.4-P4.7,P6.5,P6.6按下述6种组合依次输出： P6.6 111110 P6.5 111101 P4.7 111011 P4.6 110111 P4.5 101111 P4.4 011111 在每组行输出时读取P4.0-P4.3，若全为"1"，则表示为"0"这一行没有键闭合，否则有键闭合。由此得到闭合键的行值和列值，然后可采用计算法或查表法将闭合键的行值和列值转换成所定义的键值。 4、为了保证键每闭合一次CPU仅作一次处理，必须去除键释放时的抖动。- 24-key keyboard program, Pin description and connection Column line: p4.0 p4.1 p4.2 p4.3 as input Line line: p4.4 p4.5 p4.6 p4.7 p6.5 p6.6 as output 1, testing whether the current key is pressed. Detection method is to P4.4-P4.7, P6.5, P6.6 output all "0", read the state of P4.0-P4.3, P4.0-P4.3 as if all "1" , no key closure, or a button closure. 2, remove the key jitter. When a key is detected, the delay time to do some testing to determine the next step. 3, if a key is pressed, which should identify a key closed. The line is the keyboard scan lines. P4.4-P4.7, P6.5, P6.6 followed by combination of the following six kinds of output: P6.6 111110 P6.5 111101 P4.7 111011 P4.6 110111 P4.5 101111 P4.4 011111 To read each line of output, P4.0-P4.3, if all is "1", then "0" key to this line is not closed, or have key closed.
