新人求教，初学４３０单片机，关于这个定义引脚有点看不懂，求帮助请问#define CLK_ABIT1//P8.1--->>CLA_A为什么能确定CLK_A是接的P8.1，而不是别的.１啊？

大家好，我是学位学生，我目前正在从事T＆amp; M项目，该项目涉及编写VEE程序以自动化测量过程。我在使用Direct I / O与仪器通信时遇到问题。我使用的是非安捷伦仪器，我使用的是Rigol DS1102E数字示波器。问题：我尝试通过Direct I / O使用SCPI命令从仪器读取跟踪数据，只能使用Read Text x作为str来获取完整的返回数据。当我尝试在Array1D中使用Read Binblock x作为二进制时，我将遇到超时问题或数据数据解码不完整或者每次按下模拟都没有找到数据并且结果不一致，我应该从返回的数据中得到600点。当我使用Agilent Interactive I / O和I / O监视器来了解返回的数据时，读取过程是正确的，返回的数据是HEX并转换为ASCII。返回的消息请参见附件IO Montor Result.png。根据我对IO Monitor结果的理解，我知道返回的数据是在无符号Int8中，因此，我首先使用ToFile对象使用Read Text x作为str保存数据，并使用FromFile Object将Read Binblock x作为Binary读回数据在Array 1 D中，返回的数据能够完全解码。问题：为什么Direct BinBlock x作为直接I / O事务中的二进制Array1D无法完全解码返回的数据？是否需要对缓冲区大小进行任何设置或者我缺少哪一步？请指教。谢谢你，Jeremy Tan 以上来自于谷歌翻译 以下为原文Hi all, I am a degree student and I currently working on a T&M project which involved in writing VEE program to automate a measurement process. I face a problem on using Direct I/O to communicate with the instrument. I am using non Agilent Instrument, I am using Rigol DS1102E Digital Oscilloscope. Problem: I try to Read the trace data from the instrument using the SCPI command via Direct I/O, the was only able to use Read Text x as str to get the full returned data. When I tried to use Read Binblock x as Binary in Array1D, I will have a timeout issue or data data decoded incomplete or no data found every single time I pressed simulate and the result was not consistent , I should get 600points from the returned data. When I use the Agilent Interactive I/O and the I/O monitor to understand the returned data, the reading process was correctly and the returned data is in HEX and converted into ASCII. The returned message see attachement IO Montor Result.png. From my understanding through the IO Monitor result, I know the returned data is in unsigned Int8, therefore, I first save the data by using Read Text x as str using ToFile object and read the data back using FromFile Object with Read Binblock x as Binary in Array 1 D and the returned data was able to completely decode. Question: Why the Read BinBlock x as Binary Array1D in the Direct I/O transaction cannot completely decode the returned data? Is it I need to do any setting on the buffer size or what step I am missing? Please advise.Thanks Regards, Jeremy Tan附件IO Monitor Result.png20.8 KB

你好所以我尝试使用ACY8C24123A来计算时间，我使用一个在32千赫上运行的8位计数器，并使它在终端计数时中断。每当它中断时，我给整数加1，1等于0 08s或8ms。32000/256＝125 1s/125＝0008，但如果我尝试并计算60秒，它将计数63秒。我计算的时间越长，得到的错误就越多。90是94，5我不知道哪里有问题。计数器与处理器同步运行。 以上来自于百度翻译 以下为原文Hello So I try to count time using a CY8C24123A I use an 8bit counter running on 32 khz and make it interrupt at terminal count. Every time it interrupts, I add 1 to an integer, 1 is equal to 0,008s or 8ms. 32000/256=125 1s/125=0,008 But if I try and count 60 seconds, it will count 63 seconds. And the longer I count, the more wrong it will get. 90 will be 94,5 I cant figure out where I can have a problem. The counter is running sync with the processor.

我是一个过时的电脑用户，从Pong天C64 / 128，Amiga，英特尔......我正在研究MS发生的事情，并想知道他/她们什么时候会跳转到并行处理的电路板。他们正在推出当前的硬件，并且即将在每个人的办公桌上烧掉一个洞。我现在可以在冬天用2台电脑加热我非常古老的小房子..（不要吝啬）..我能看到的唯一进步是IF，他们将硬件改为并行。Current总线架构不够快，而且当前硬件上的带通无法处理它。CPU很好（我想）但其余的硬件都是TRYINg来跟上..有任何想法吗？可以使用当前窗口完成并行处理。完全升级会发生多少变化？以上来自于谷歌翻译以下为原文Im an old time computer user, from the Pong days the C64/128, Amiga, intel...And Im looking at what is happening with MS, and wondering IF/WHEN they will make a jump to parallel processed boards.They are topping out on the current hardware, and about to Burn a hole in everyones desk.I can NOW heat my Very old small home with 2 computers int he winter..(NOT LYING)..The only advancement I can see is IF, they change the hardware to parallel..The Current bus architecture, isnt fast enough, and the bandpass on the Current hardware cant handle it.. The CPU is fine( I would think) but the rest of the hardware is TRYINg to keep up.. Any Ideas?Can Parallel processed be done with the Current windows..and how much of a change would happen with a full upgrade?
