求一个PM2.5检测仪的Arduino源程序

ID:111876 · 发表于 2016-4-16 08:50

购得夏普GP2Y1010AU0F 传感器，手头有我自己写好引导程序的ATMEGA328P的芯片，有Arduino R3板（可往芯片里写程序），还有1602液晶屏，想用自己搭建的ATMEGA328P最小系统，制作一个PM2.5检测仪，，只差可用的源程序了，在网上没有搜到可用的，请哪位有的朋友，给我传一个，1602屏要用四线制驱动，多谢了！

谢谢版主！但他那个似乎是51单片机的，而我用的是ATMEGA328P的单片机芯片，需要的是Arduino的源程序！

网上找了个源代码，做了一些改写，现在已经成功了，这是我学习单片机一个月以来，做成的第一个小东西。有成就感，高兴啊！哈哈！

下一步打算用手头就有的89C2051单片机，加上1602显示屏，使用坛友送我的SP200S编程器写程序，做一个能测量电感，电容的单片机LC表！这样的LC表还是有一定的使用价值的！

谢谢，但是I2C的板子很难伺候，我网购了2块I2C转接板，用时一周，把网上能搜到，能问到的所有办法都试过了，结果是1602屏不能正常显示，，最后又返回来使用四线式连接，才解决的问题！！去他地吧I2C！！

楼上的先生，再仔细一看你上传的程序，是一个采用1302的时钟源代码啊！

ID:117823 · 发表于 2016-6-4 01:38

可以用，我用了10个pcf8574 iic模块1602可以正常使用，很简单的。我采用的是ds1302代码，库文件可以在网上找，大多类似。
