玩玩LED点阵屏（arduino nano）

做些记录，特别是led显示左移效果的代码，二进制位的特效函数

最后，虽然是能显示，也能左移，但是由于没有自带文字库，所以都靠自己画点，麻烦，以后不干这事了，还是买入整体为好，这么太折腾了。

arduino nano 配合 as32-tll-100串口通信实验 --基础串口通信

Arduino Nano 超小封装的 Arduino开源系统.玩起来挺爽的. 作为最小单片机系统,首先功耗是没得说,很低很低,并且还有休眠模式,采用电池供电非常理想的功耗. 其次,由于社区完整强大,扩展很方便,无论串行并行,编程接口丰富. 再次,价格很感人,RMB:10-20元.依然是首选. AS32-TTL-100是一款基于Semtech原装SX1278射频芯片而开发,工作频段为410-441MHz,功率为100mW直插式串口数传模块.该模块采用LORA扩频传输,接收灵敏度高,功耗低,距离远.

Arduino Nano + WIZ550io = 简易上网

我爱Arduino Nano – 这是一个非常好外形小巧却功能齐全的Arduino Uno.然而.当我去将它连接到互联网,全部的干净利落小巧也消失在大尺寸的以太网盾底下了. 只是,我近期发现了一个更好的,更紧凑的方式给我的nano连接到互联网 – 通过使用WIZnet公司小巧得多(且更廉价)的WIZ550io模块! 假设你想方便连接,你能够找到一个可连接该模块和Arduino Uno的适配器板,但我想保持小巧的子板.通过我的Nano把它们直接连接在一起.然而.假设你没有适配板,你能够利用同样的方

最新 Arduino 驱动 12接口/户外 LED显示屏/LED点阵屏/LED单元板

起因 现有的驱动LED显示屏的资料,比较好的只有这个.但是它驱动的是08接口的室内显示屏,而我要驱动的是12接口的户外显示屏.两种屏幕的区别在于户外屏幕点阵比较稀疏,而且二者的扫描方式,驱动方式都不太一样.我花了一个下午才摸索出了它的使用方式,因此分享给大家,希望大家不必再绕弯路. 材料准备 12接口(户外)LED单元板一块:比如我是从[这里]买的,大家搜索“半户外 LED 单元板”就可以了.我的板是16x32大小. Arduino Uno一块 5V电源一个(比如充电宝.给手机充电的头) 硬件搭
