创意小发明：山寨码表.自行车码表的制作 程序原理图，设计图，源代码

最近比较懒，因缺乏锻炼,加上之前上了2个月的"长夜班",身体有米其林化的趋势.为了阻止这种不良的发展.决定买个二手自行车在家骑自行车锻炼锻炼.

但是很快发现光骑车没劲,于是出于好奇心里 做个码表装上看看能骑多少快,骑了多少路.

废话不多说，先上实物图： 虽然样子有点丑，但是显示效果还是可以滴

单片机用stc89c52，因为之前买了几片还没用掉,因为它只要3块多钱,因为我只要几个IO加上外部中断,定时器. 显示用yleee的12232液晶,因为已经放了快2年了.3片只用掉一片,而且做完之后依然压箱底. 不用掉浪费. 电源用白菜模块做单锂升压到5.2v来使用. 因为买了太多了,不用掉浪费. 电池暂时找了块yleee的太阳能移动电源中的大肚子锂聚合物电池. 当时肚子很大,电压很低.给它捅了一刀以后继续充电,身材恢复苗条,就是有点皱纹. 500ma放电能有3,400 mah容量. 传感器用了大家都说好的干簧管,还是从中学劳技课的板子上拆下来的. 磁钢安装就尽显山寨本色了. 既然画了PCB,就顺便加上了 1302， 18b20，万一没事干又想加上去了. 板子继续热转印,这次买了瓶新的三氯化铁,放在新买的电磁炉里水浴加热到80°,竟然还花了10几分钟. 期间还把三氯化铁滴到了锅子里,以后吃火锅能吃到正宗的化学锅底了. 恩. 这是之前的试做版本.

话说制作期间,一天都没运动过,终于在第六天倒下了,去医院把我全新的医保卡上写上了历史性的一页,而配的药的纸壳,就成了这次的山寨码表暂时蜗居的地方.

刚才完成基本功能,发现我的破车骑在20km/h已经很吃力了. 全力只能跑到30km/h. 看来也就这水平了. 为了看得清, 用了四倍字体大小. 很给力. 界面就改成这样了. 显示这些东西也够看了 按第一个键保存总行程. 第三个键背光开关. 开机时摁住第一第二键 总行程清零.
