考虑使用各种类型的数组来替代列表。array模块支持不同的项类型,8位项由的内置bytes和bytearray类支持。 这些数据结构将项储存在连续内存位置中。为避免在临界区代码中分配内存,内存应进行预分配并作为参数或限定性对象传递。 在传递诸如bytearray实例之类的对象片段时,Python会创建一个副本,该副本涉及与片段大小成比例...

1.在这里,导入espnow之后,先实例化一个对象并激活。 2.在使用espnow收发数据之前必须先启用Network.STA_IF或者Network.AP_IF,如果不需要wifi转发那就不需要连接或者配置 3.ESPNow.send(mac,msg)注意消息发送消息长度不大于250bytes,如是长度大于250bytes时切包再合包。
