问题描述

虽然使用函数ReadFile(??)从串行端口获取数据，但如何指定所需的数据应仅为二进制形式(纯数据)，而不应为十六进制或无符号字符?

在此先感谢

Whilest using the function ReadFile(??), for getting data from a serial port, how do you specify that the data you want should be only in binary form, (pure data), and not hex or unsigned char?

Thanks in advance

推荐答案

您无需指定任何内容:ReadFile确实会读取原始二进制数据.
如果您收到十六进制"(即数据的十六进制表示形式)，则表示对方正在向您发送该信息.

You don''t need to specify anything: ReadFile does read raw binary data.
If you get ''hex'' (i.e. the hexadecimal -textual- representation of the data) it just means the other side is sending you that.

谢谢，很好的回答.我使用的是无符号字符作为缓冲区，所以我想可以改用LPVOID缓冲区[?]，看看情况是否有所变化，但我相信您是正确的！

Thanks, great answer too. I was using an unsigned char as its buffer so I think I can use an LPVOID buffer [?] instead and see if things change but I believe you are correct!
