PIC16F887A与arduino串行通信出现问题

问答对人有帮助，内容完整，我也想知道答案 0 嗨，我试着在PIC和ARDUNO之间进行串行通信。但PIC不会“读取”正确的价值。有人可以看看我的代码，看看有什么不对。是的，我已经检查了ARDUINO正在输出一个值。我把接收文件作为一个TXT文档而不是A.Inc，因为我不能把它作为一个包含文件在这里。希望你能找出答案。语言是在丹麦，所以如果你有任何问题，只要问或使用谷歌翻译：P.BTW PORTB被设置为8个LED显示值在二进制。BRG乔纳斯 EKSAMSENPROJEKT ASM（3.02 KB）-下载35次以上来自于百度翻译以下为原文 Hi. I've tried to serial communicate between this pic and arduino. But the pic wont "read" the value right. Can somebody take a look at my code to see whats wrong. And yes i have checked that arduino is outputting a value. I put the reciever file as a txt document instead of a .inc because I can't put it as an include file here. Hopefully you can figure it out anyway. The language is in danish so if you have any questions regarding, just ask or use google translate :P. Btw PORTB is set to be 8 LEDs to show the value in binary. brg Jonas Attachment(s) Reciever.txt (2.63 KB) - downloaded 29 times Eksamensprojekt.ASM (3.02 KB) - downloaded 35 times 0

答案对人有帮助，有参考价值 0 我看到一些问题，但不是你的问题的原因。不要设置RCIE。这仅仅是为了产生中断，因为GIE没有被设置，所以你在逃避。如果设置了GIE，程序将崩溃，因为没有中断服务例程。RCIE不屏蔽RCIF位。停止尝试清除RCIF。那个位是只读的。唯一可以清除的方法是读取RCREG寄存器，这是你已经在做的。不要试图清除RCREG。那个寄存器是只读的，它到底在读什么吗？如果是，什么输入给出什么输出？是ARDUNO输出TTL串行，还是RS232串行？在ARDUNO和PIC之间有RS232缓冲吗？以上来自于百度翻译以下为原文 I see some things wrong, but not the cause of your problem. Do NOT set RCIE. That is only for generating interrupts. You are getting away with it because GIE is not set. If GIE was set, your program would crash because there is no interrupt service routine. RCIE does NOT mask the RCIF bit. Stop trying to clear RCIF. That bit is read-only. The ONLY way you can clear it is by reading the RCREG register, which you are already doing. Don't try to clear RCREG. That register is read-only. Is it reading anything at all? If yes, what input gives what output? Is the Arduino outputting TTL serial, or RS232 serial? Is there any sort of RS232 buffering between the Arduino and the PIC?
