LCD12864 翻页显示求助
arduino mega 2560+攀藤 G1（pm2.5传感器）+DHT22+LCD12864目前可以通过LCD实现单页显示（仅显示中标的pm2.5以及DHT22的温湿度），由于G1可传感数据比较多（中标，美标以及颗粒物数），想通过两个按键来实现LCD上下翻页来实现所有数据的显示。求代码或相关例程！
感谢万分！！！ 自己顶一个，别沉了！ 像這樣嗎?還在測試中,做得不是很好.
能否看一下代码，学习学习！ jasonwang1208 发表于 2017-4-8 21:11

谢了！你的pm2.5传感器是哪一款？ wwwyyy317 发表于 2017-4-10 15:41
