我使用了文本编辑器,并将文件保存为 file_io.py。 # Example code to demonstrate writing and reading data to/from files# Step 1: Create a file and write some datanew_file =open("log.txt","w")# use "write" modenew_file.write("1,apples,2.5--n")# write some datanew_file.write("2,...

The only thing that is controllable is the size of the partitions made on the flash storage and the speed of the memory/flash and the read/write mode that is being used... Perhaps the correct read/write mode is not being used?? I would need a link to the website where you purchased...
write("d") uos.dupterm(None, 1) # disable REPL on UART(0), detach the REPL from UART0 if __name__ == "__main__": actSeq() 当我们执行actSeq()函数时,就可以通过串口输出一系列指令。使用串口监视器我们可以进行调试。 使用串口监视器监控输出如下(为了方便阅读我使用了串口调试器的自动断...

因此在MicroPython中,推荐使用 write() 方法,该方法对阻塞套接字实行相同的“无短写”方法,并将返回在非阻塞套接字上发送的字节的数量。 socket.recv(bufsize)¶ 从socket上接收数据。返回值是一个表示接收到的数据的字节对象。要接收到的数据最大数量由缓冲区大小指定。 socket.sendto(bytes, address)¶ 将...
