IERG 3810
(Microprocessor System Design Laboratory) )is the first lab course in CUHK.And since I have never attend the lab in CUHK before, I feel curious about it ,and of course ,a little bit nervous.
My lab course is at 2:30 p.m in Tuesday afternoon, my friend who has attended the class on Monday told me that he had not finished the experiment in the lab time .He reminded me that I should start the experiment as early as I can with my partner Wu.Oh,no,we have to face challenge again in the evening.

The first experiment is Schematic Drawing and PCB Design,i even don’t know the meaning of PCB design since I did’t do any circuit design in the lab before.The software OrCAD, I even don’t hear about it.I console myself that the first experiment will be easy, but the moment I open the “demo.pdf”,I’m shocked.
Why I’m shocked? Because I even don’t know what the logo of OrCAD it is,and complete the job on OrCAD is one part of this experiment. Oh...

| I'm crazy |
(Crazy......)
But the bad feeling disappears rapidly as soon as I find the two other document. The content in the document tells us step by step about what should we do firstly,secondly, etc. Each step gives us a picture to show clearly.For example:
Even I don’t anything about OrCAD, I can achieve my aim to draw a circuit diagram as the demo shows through the procedure in pdf.
During the experiment,my partner and I take turns to work. Each person works for 45 minutes and then the other will continue,which guarantees the efficiency.

I think the most troublesome problem is searching for the proper component.There are so many component in the software and I can’t find the component I need in a short time.I have a discuss with my partner , and finally we have figure out the function in the software that we can input the first letter of the component’s name,and then we will find the proper component soon.

That night, we have worked for nearly 4hours to complete the first mission of Lab 1, I have never experience working in the midnight in the mainland,but here ,in ERB1007,I feel excited when I finally get the result.I even don’t feel tired.
In the next day ,we continue doing the second process--lay out.It means we have to make the circuit diagram we have done suitable for PCB design.(In the demo we have seen that all the devices are not connected with wires,but after lay out,it looks like a real PCB design.) Just as what the PDF says, finally we get the result:
Do you think that the first experiment is over ?Oh no, half of the mission has been done. I need to do the experiment report.The English report is not just as the same as Chinese report.Since the teacher doesn't say anything about the report.I have to search the comments on the Internet. A English report contains the 7 parts which are listed in the below：
1.Abstract
2.Introduction
3.Method
4.Results
5.Discussion
6.Conclusion
7.Reference
And finally,I got the report：
