EN我做同样事情的选择是定义_PLATFORM变量，相应地设置它，然后使用它：
() -- convert 16, 32 bit int from network to host byte order htons(), htonl() -- convert 16, 32 bit int from host to network byte order inet_aton() -- convert IP addr string (123.45.67.89) to 32-bit packed format inet_ntoa() -- convert 32-bit packed format IP to string (...
前段时间南京的一起电动车自燃事件造成了众多人员伤亡,引起了大家对电动车起电事件的关注,我觉得在电动车停放区安装一个火焰检测器应该是一个不错的选择,所以我就想到了使用MicroPython基于RP2040开发板实现火焰传感器实时监测。 实验接线图 火焰传感器接线图

Note that most string methods (e.g. str.strip()) apply also to bytes instances so the process of eliminating Unicode can be painless. s = 'the quick brown fox' # A string instance b = b'the quick brown fox' # A bytes instance Where it is necessary to convert between strings and...
