我还没有与图片在6YRS（一直在阿杜诺），但…他们花了很多钱，有一个贫血的外围设备和RAM，所以我回来了，而且我很难让一个更新的人做任何事情。我做了：创建新的项目，选择MPASM和ICD3

我同意Shawn的最后评论......基本上有人离开了大楼并随身携带了代码，或者留下了任何东西，以及给你留下定制卡。 Â我想，看看你的输入和输出，并从头开始重建，ÂHMI（Vee将比15年计划更好）程序...... Vee将运行得更快（比10年前的C程序.....因为传统的.Interface ....至少现在你正在标准化....硬件.....给信息？......可能可以廉价更换。替换成本$我无法与之交互它>使用VEE并且无法实时读取测试>结果。是否有activeX>控件来执行此任务？否。>如何通过串行端口读取这些数据？分析原始电路。有一些技术可以连接到一个进程并控制它的输入并读取它的输出，但前提是原始程序使用标准库。如果它正在读取键盘并在不通过标准库的情况下写入屏幕，那么您将不得不做很多工作来自动完成。刷新你的机器语言。你需要它（也就是说，在VEE中不会发生 - 这是肯定的）.2。这是一个折腾。要么弄清楚原来的董事会做了什么，要么抓住会议并以这种方式弄清楚。 VEE可以处理串行端口，但RS-232并不是唯一的野兽。有很多线程协议与任何已发布的标准无关。我的意见是完全重新设计并重建测试而不是自动化现有测试。

我认识到我必须从MPLAB 8移动到MPLAB X，但是，现在两个都下载了，我非常害怕。至少“8”给了直觉工作的机会——“X”一点都没有，据我说，“折射器”之类的术语让我起鸡皮疙瘩。这里的人能推荐最好的教程吗？E？谢谢 以上来自于百度翻译 以下为原文 I recognize that I must move to MPLAB X from MPLAB 8 but, having both of them now downloaded, I am quite intimidated. At least "8" gives some chance for intuition to work - "X" none at all, according to me - and terms like "refractor" give me goose bumps. Could people here please recommend the best available tutorial for those wanting to make this transition - one that actually talks to human beings in plan language? Thanks

我是一个需要帮助的新手。我想用最初的这个.ASM文件来执行一个无线控制时钟（不是我的项目）。不幸的是，我不知道我得到的PIC16F628 A不适用。有人能帮助我详细地把MODS建议给这个文件，考虑到我不知道。知道大会吗？谢谢你 以上来自于百度翻译 以下为原文 I'm a newbie needing help.I would like to carry out a radiocontrolled clock (not my project) using originally this .asm fileUnfortunately I didn't know that the PIC16F628A that I got,doesn't work with it.Can someone help me suggesting in detail the mods to this file,taking into account that I don't know the assembly?Thank you Attachment(s)dcf77.asm (14.01 KB) - downloaded 148 times

我在PIC24FJ128GA202上使用SoSC来运行RTCC模块，我有一段时间让它稳定。RTCC启动和停止，当它运行时，它不会保持良好的时间（+/-每秒钟一秒！）我使用的是一个IQD 32768千赫石英晶体，它具有12pF负载电容和2pf并联电容。我已经尝试过使用10pF到50pF的电容器，在性能上没有明显的差别。这就是我所看到的：范围显示它在正确的频率附近振荡，但是幅度只有大约300 mV。我有一个探险者板，我把晶体从它上拉下来，WHI。CH给了我更多的信号，但仍然不一致。把一个范围放在探险者板PIM上，我看到它也有非常低的振幅，可能是400毫伏左右，但是它确实有大约1/2伏的偏移量。我没有看到任何抵消我的项目。我尝试打开RTCC输出设置到时钟，但看不到该引脚上的任何活动。这里是我所尝试的：改变电容值。在晶体上增加1M分流电阻器。将晶体从探险者板上切换。打开弱拉O。SoSi引脚。问题：什么是一个良好的晶体和电容器组合这一部分？当振荡器正常工作时，我应该从振荡器中看到什么样的电压和偏移量？我错过了什么？？？？我的其他项目运行良好，包括2个AD转换器输入，2个UART，LCD显示，以及其他各种iOS。如果我能让RTCC做我应该做的，我会是一个快乐的家伙！请帮忙。 以上来自于百度翻译 以下为原文 I'm using the SOSC on the PIC24FJ128GA202 to run the RTCC module and I'm have a heck of a time getting it to be stable.The RTCC starts and stops, and when it does run it does not keep good time (+/- one second every minute!).I'm using an IQD 32,768 khz quartz crystal, which has a 12pf load capacitance and 2pf shunt capacitance.I've tried using capacitors from 10pf through 50pf for the tank with no noticeable difference in performance. Here's what I see: The scope shows it is oscillating at around the correct frequency, but the amplitude is only about 300mv.I have an Explorer board, and I pulled the crystal off of that, which gives me slightly more signal, but is still inconsistent.Putting a scope on the Explorer board PIM, I see that it also has very low amplitude, maybe 400mv or so, but it does have about a 1/2 volt offset.I do not see any offset on my project.I tried turning on the RTCC Output set to the Clock, but see no activity on that pin at all.Here's what I've tried:Changing capacitor values.Adding a 1m shunt resistor across the crystal.Swapping the crystal from the Explorer board.Turning on the Weak Pull Up on the SOCSI pin.Questions:What's a good crystal and capacitor combo for this part?What sort of voltage and offset should I see from the oscillator when it's working properly?What am I missing here???The rest of my project is running well, including 2 AD converter inputs, 2 UARTS, LCD display, and various other IOs.If I can get the RTCC to do what it's supposed to I'll be a happy guy!Please HELP.

您好，我正受到PNA-X校准问题的挑战。我在PNA-X上设置了多个通道，用于放大器的生产测试，其中通道的硬件配置相同（避免衰减器切换和IMD路径的机械切换）。在相关通道上，我使用增强响应校准来避免反向扫描。在一个通道上，我正在执行功率扫描以获得放大器压缩数据。我使用src / rx功率校准在此通道上执行增强响应校准 - 它简化了校准设置的自动化，我希望我能免费获得一些不匹配校正。我在端口2源衰减器上有一些源衰减（出于其他信道考虑），但会认为这对于该信道无关紧要。但是，当我启动校准时，我得到一个Unleveled源1，输出2错误。发生这种情况是因为我的P2源衰减值无法实现功率扫描中的Pstop。但是，鉴于这是增强型响应校准，我认为不匹配误差项都是通过驱动端口1（3个P1反射项，负载匹配和传输跟踪）获得的。因此我不知道为什么端口2被驱动（因此导致我的无法解决的错误信息） - 小蓝灯告诉我端口2被驱动:(校准的src / rx cal部分是否导致P2被驱动？是有一种方法可以解决这个无法解决的问题吗？谢谢你 以上来自于谷歌翻译 以下为原文Hello, I am being challenged by a PNA-X calibration issue.I have several channels setup on my PNA-X for production test of an amplifier in which the hardware configuration of the channels is the same (avoid attenuator switching and mechanical switching of IMD paths).On relevant channels I am using Enhanced Response calibration to avoid the reverse sweep. On one channel I am performing a power sweep to obtain amplifier compression data.I perform a Enhanced Response calibration on this channel with src/rx power calibration - it simplifies automation of the calibration setup and I hope I am getting a little mismatch correction thrown in for free.I have some source attenuation on the Port 2 source attenuator (for other channel considerations), but would think that this should not matter for this channel.However, when I initiate the cal, I get a Unleveled source 1, out 2 error.This occurs because my Pstop in the power sweep cannot be achieved with my P2 source attenuation value.However, given that this is a Enhanced Response calibration, I would have thought that the mismatch error terms are all obtained by driving Port 1 (3 P1 reflection terms, load match and transmission tracking).Thus I do not know why Port 2 gets driven (and hence causes my unleveled error message) - the little blue light tells me that Port 2 gets driven :( Does the src/rx cal part of the cal cause P2 to be driven?Is there a way I can workaround this unleveled issue? Thanks andy
