使用带有PIC16LF1459的RFID-RC522

你可以先给我们你的安装原理图。再加上整台钻机的一些照片。

    You might start with giving us the schematics of your setup. Plus eventually some photos of the whole rig.

那么你有3 V系统吗？（BTW：MISO和SCK上传似乎已经破产了，我无法访问。）但是：你知道SCL和SDI上还有更多任务吗？（HDC1080，NFR24L01，OPT300）和MOSI信号有点奇怪-显示这个缓慢过渡到GND（右侧），这是我不期望的。



      以下为原文

    So you've got a 3 V system ?
(BTW: MISO and SCK uploads seem to have gone bust - being not accessible for me.)
BUT: are you aware that there exist some more quests on SCL and SDI? (HDC1080, NRF24L01, OPT3001)
And the MOSI signal is somewhat weird - showing this slow transient to GND (right side) which I wouldn't expect.

是的，我有一个3V系统。我需要通过NFR24L01发送关于门状态的信息（打开或关闭）。所以我知道这个模块也会使用SPI。新的PIC来自于StasOpCopeMIS:http://Dr.GooLe.com /Fiel/D/C79WFDJ9CSVRBGMXXBVLPGHQQGPILIQQMOSI：http://驱动器。谷歌。com…/ VJ1BJQDJLCSO5BY0F2TWQA



      以下为原文

    Yes i have a 3V system.
I will need to send by the nrf24l01 the information about the status of the door (open or close).
So i know that there is this module which will use the SPI too.

OK -你的主顾有风险。有点可疑的是第616行中的“继续”。建议删除它，因为它肯定没有“积极”的使用，但可能会出现一些负面影响。



      以下为原文

    OK - risked an eye on your main.c
What's somewhat dubious is the "continue" in line 616. Suggest to delete this as it definitely has no "positive" use but might exhibit some negative effect.

I2C组件没有填充吗？这些可能会不经意地“抓住”某些东西，干扰SPI操作。另一方面，我目前在押注“继续”。



      以下为原文

    Are the I2C components unpopulated?
These might inadvertently "catch" something and interfere with the SPI operation.
On the other hand I'm currently betting somewhat on the "continue".

我在他的根文件夹中看到的唯一的C文件是“Maun2.c”，它只有107行，没有“继续”语句。



      以下为原文

   
The only C file I can see in his root folder is "main2.c", and that only has 107 lines, and no "continue" statements.
 

谢谢你的帮助，我对我的旧程序一无所知，所以我修改并上传了一个新的。

嗨，有人有主意吗？谢谢你



      以下为原文

    Hi,
 
Someone got an idea ?
 
Thank you

我建议首先将编译器选项设置为-WALL，并取消所有编译器警告。最后，开始初始化RFID阅读器（至少在源代码[/OS]之间的代码中，我不能看到RFID阅读器的任何初始化）。这可能对DE有进一步的帮助。长度误差和其他误差之间的关系如MieErr目前只说明“有些事情是错误的”-没有进一步的诊断能力。在顶层进行函数而不是仅仅进行“调试”，无疑会有助于找到错误。



      以下为原文

    I'd suggest to start with setting the compiler options to -Wall and get rid of all compiler warnings.
Eventually proceed with initializing the RFID reader (at least in the code goven above between [ source ] / [ /source ] I cannot see any initialization of the RFID reader).
It might further help to descern between the length  error and other errors as MI_ERR is currently only telling "something is wrong" - without further diagnosis capabilities. And stepping into the functions instead of just "debugging" on the top level would certainly help to find the error(s).

这是初始化：我把这个添加到触控者的代码中。

  __delay_ms(2);
  writeToRegister(ModeReg, 0x3D);        // CRC initial value 0x6363
  __delay_ms(2);
 //writeToRegister(TxControlReg, 0x82);     
  __delay_ms(2);
 //setBitMask(TxControlReg, 0x03);        // Turn antenna on.
  AntennaOn();
}

 
I add this to the code for the antenna

void AntennaOn(void)
{
    unsigned char temp;

    temp = readFromRegister(TxControlReg);
    if (!(temp & 0x03))
    {
        setBitMask(TxControlReg, 0x03);
            REDLED = 1;
    }
}

void AntennaOff(void)
{
    clearBitMask(TxControlReg, 0x03);
}

 
i got theses warnings

OK -您可以保留警告（520）（函数XXX从未被调用），但是要去掉其余的！考虑到隐式类型转换的警告等，提高希望——也许只是——一旦多余的警告被消除，你就会得到线索。P.S.：当计算机101讲座举行时，你在哪里度过你的时间？



      以下为原文

    OK - you may keep the warnings (520) (function xxx is never called), but get rid of the rest!
Considering warnings about implicit type conversions etc. raise tha hope that - just maybe - you'll get a clue once the superfluous warnings are eliminated.
 
P.S.: Where did you pass you time when the computer 101 lectures were held?

嗨，我猜引脚连接是错误的，来自RC522的MOSI与PIC和MISO从RC522到SDI一起去SDI



      以下为原文

    Hi I guess pins connection are wrong, MOSI from RC522 go with SDO from PIC and MISO from RC522 go with SDI
