您好，我正在使用：PIC24FJ256GA705好奇心开发板，带有一个M2323-GT；RS232--GT；USB连接到PC适配器，连接到UC内部的UART1模块。我已经设法把传输传送到PC，但是在每次传输之后都有一些随机字符是杂乱无章的。（如图所示）有人能解释一下为什么会出现在这里吗？如果你能指出我的代码中的任何错误和可能的改进，我将非常感激。我为代码的长度道歉，我已经删除了大部分不相关的代码。对不起，如果我的格式不是很好，这是我的第一个论坛帖子。（张贴说，访问被拒绝，所以编辑帖子一旦张贴）感谢任何帮助！实际上，它现在在实际数据之前发送一些随机字符。传输之间的时间也不一致（第一LED闪烁，延迟，闪烁闪烁）（TX LED），我看不出为什么它会永远循环？串口阅读器图像不会上载，所以我会尝试上传一个回复。P.S.如果你看到这个，DarioG你居然帮助了难以置信地不知道它。我非常感谢你对这些论坛的贡献！以上来自于百度翻译 以下为原文 Hi, I am using: PIC24FJ256GA705 Curiosity development board, with a Max2323 -> RS232 -> USB into PC adapter, connected to the UART1 module inside the uC.I have managed to get the transmission to PC, but after every transmission there are some random characters that are gibberish. (shown in picture)Please could someone explain why these are here? I would be incredibly grateful if you could point out any mistakes and possible improvements to my code.I apologise for the length of code, I have removed most of the irrelevant code. Sorry if my formatting isn't very good, this is my first forum post. (posting says access denied so will edit post once posted)Thanks for any help! Actually it is now sending some random characters before the actual data. Also the time between transmissions isn't uniform (1st LED blink, delay, blink blink) (Tx LED) and I can't see why it loops forever?The serial port reader image wont upload so I will try to upload in a reply. P.S. If you see this, DarioG you have helped incredibly without knowing it. I am very grateful for your contribution to these forums! Attachment(s)codeOutput.jpg.zip (8.67 KB) - downloaded 10 times
