模拟器寄存器从文件注入的问题-MPLABX 4.10 - PIC16F1825

当我将串行端口设置为缺省条件CREN＝1，Syc＝0，SPEN＝1，等待RCIF清除时，我在RCREG寄存器中获取字符，但是它们不对应于注入文件中的值：BTW，如何在文件中放置注释？我认为他们只是前面的“；”还是“//”？[编辑]我尝试了“；”并且得到了一个错误“没有找到源代码行……”。“//”看起来不错，但其他问题仍然存在。[编辑2]我找到了一种在串口上模拟字符流的方法：



      以下为原文

    When I set up the serial port to default conditions CREN=1, SYNC=0, SPEN=1, and wait for RCIF to clear, I am getting characters on the RCREG register, but they do not correspond to the values in the injection file:
66
32
49
50
51
52
13
88
13
 
BTW, how can comments be placed in the file? I think they are just preceded by ";" or "//"?
 
[edit] I tried ";" and got an error "No source lines found...". The "//" seems OK, but other problems remain.
 
[edit2] I found a way to simulate a stream of characters on the serial port:

char    RXDsim[] = {'B',' ','1','2','3','4','n','X',''};
int     RXDptr = -1;
char    EUSART_Read(void) {
//    while(!RCIF);
//    return  RCREG;
    if(RXDptr < sizeof(RXDsim))
        RXDptr++;
    else
        RXDptr = 0;
    return RXDsim[RXDptr];
    }

我们能看到你的刺激寄存器注入选项卡的屏幕截图吗？不确定你做了什么，所以很难弄清楚到底出了什么问题。触发模式是非常关键的决定何时注射将发生。我甚至无法回答你的评论问题，因为不同的触发器模式有不同的读取数据文件的方式。至于使用SerChar，如果我记得正确，注册表注入需要一个实际的寄存器，你不能从程序中使用变量。这是刺激的限制，而不是SCL。（刺激是SCL的GUI前端。）



      以下为原文

    Can we see a screenshot of your Stimulus Register Injection tab? 
 
Not sure what you did, so hard to figure out what's going wrong.  Trigger mode is pretty critical in deciding when injections will occur.  I can't even answer your comment question because different trigger modes have different ways of reading the data file.

As to using SERCHAR, if I recall correctly, register injection requires an actual register, you can't use a variable from your program.  This is a limitation of stimulus, not SCL.  (Stimulus being a GUI front end to SCL.)

触发器可能被设置为“需求”而不是“消息”，这似乎是模拟串行端口所必需的。然而，我仍然有错误的字符。它们似乎是“q”、“r”、0x13和0x88。我尝试添加适当的配置词，并且在另一个串行端口工作的项目中设置OSCCon和其他寄存器，得到相同的结果。ReG/var的下拉包括SelCHar变量，这导致错误消息。通用电气公司。有两个RCREG实例，也是一个RXDSIM，但是在应用时导致了与上面相同的一个即时错误。对于模拟器来说，简单地从文件中读取并注入任何寄存器的值似乎是很容易的，就像我可以手动改变变量O中的寄存器一样。R观察窗口。但是现在我使用的方法是可以接受的。我也尝试使用PoTa来刺激，但似乎不起作用。



      以下为原文

    The trigger may have been set to "Demand" rather than "Message", which seems to be required to simulate the serial port. However, I still get wrong characters. They seem to be 'Q', 'R', 0x13, and 0x88.
 
I tried adding proper config words and I set up the OSCCON and other registers to what I have in another project where the serial port works, and I get the same results.
 
The drop-down for the Reg/Var includes the SERCHAR variable, which caused the error message. There were two instances of RCREG, and also a RXDsim, but that caused an immediate error same as above when applied.
 
It seems it would be easy enough for the simulator to simply read from the file and inject any register with the value, just as I might manually change the register in the Variables or Watch window. But for now it is acceptable to use the method I used.
 
I also tried using PORTA for stimulus, and it does not seem to work.

我确认了PORTA寄存器注入不起作用。所以我关闭了MPLABX并重新打开。它引发了一个“意想不到的异常”错误，然后该项目将不建立（没有配方构建），我得到了“互联网连接不够稳定，下载最新的工具”错误。另一个关闭和重新打开MPLABX，它建立了OK，但仍然没有乐趣与端口寄存器注销的FILo.PORTC也不起作用。我刚刚在我的WI10机器上安装了MPLAB 8.92，但是它找不到XC8。我会张贴并搜索一种方法来将它添加到已注册的工具套件中。似乎列出了所有的东西，包括CCS、XC16、XC32、C18，而不是XC8。



      以下为原文

    I confirmed that PORTA register injection does not work. So I closed MPLABX and re-opened. It popped an "unexpected exception" error, and then the project would not build (no recipe to build), and I got the "Internet connection not stable enough to download latest tools" error.
 
Another close and re-open of MPLABX and it builds OK, but still no joy with PORTA register injection from the file.
 
PORTC doesn't work either.
 
I just installed MPLAB 8.92 on my Win10 machine but it can't find XC8. I'll post this and search for a way to add it to the registered toolsuites. Seems to list everything but, including CCS, XC16, XC32, C18, but not XC8.

你如何测试门静脉注射？你把波尔塔转换成数字模式了吗？



      以下为原文

    How are you testing the PORTA injection?
Did you switch PORTA to digital mode?
 

我找不到如何在Win10上获得8.92使用XC8，所以我用我的Win8机器做同一个项目。使用PoTa（或PORTC）与PC＝EuStudioRead作为触发器，除了在0x3f上截断字符外，因为它们在PIC16F1825上只有六位。使用SerChar变量的工作非常完美。然而，RCREG似乎不起作用。触发器的选择仅是“消息”，格式仅为“PKT”。我确实将端口配置为输入和ANSELX＝0。



      以下为原文

    I could not find how to get 8.92 on Win10 to use XC8, so I used my Win8 machine for the same project. Using PORTA (or PORTC) worked with PC=EUSART_Read as trigger, except it truncated characters above 0x3f, because they are only six bits on the PIC16F1825. Using the SERCHAR variable works perfectly. RCREG does not seem to work, however. The trigger choice is only "Message" and format is only "Pkt".
 
I do have the ports properly configured as inputs and ANSELx=0.

当然模拟器可以做到这一点。棘手的部分是“何时”模拟器应该做，这就是触发模式进入的地方。需求意味着每当您的应用程序代码（或任何外围设备）试图读取寄存器时，模拟器将获取下一个值。消息意味着模拟器可以选择何时注入。这真的只与UART接收（和ADC缓冲区在旧风格模式）。当UART波特率指示接收下一个字符的时候，模拟器将被注入。为了解决特定的错误，我们需要看到你的刺激设置和特定的错误。

Of course simulator can do this.  The tricky part is "when" the simulator should do it, and that's where the trigger mode comes in.  Demand means that every time your application code (or any peripherals) attempt to read the register the simulator will fetch the next value.  Message means that the simulator gets to choose when to inject.  This really only works with UART receive (and ADC buffers in old style mode).  Simulator will inject when the UART baud rate dictates that it is time to receive the next character.


To address specific errors, we would need to see your stimulus set up and the specific error received.
