原来写了一个C++的wifi库但是发现用c++ arduino这小身板有点扛不住,代码比较大,使用String类型数据处理速度慢,而且很容易无缘无故跑飞。而且封装成库后使用还需要修改arduino的串口缓存大小才能使用。 今天抽空重新用c写了一下代码,运行速度明显加快,也不需要修改Arduino IDE了。本代码主要借鉴 中移物联-周家绪 的ht...
The usual PROGMEM attribute stores constant data such as string arrays to flash and is great if you want to preserve the precious RAM. However, PROGMEM will only store content in the lower section, from 0 and up to 64kiB. If you want to store data in the upper section, use PROGMEM1 ...
