In the first place I was talking to Kai and I never replied you Arrogantly but helped you ??
This sounds to me that he is not aware of ground return path.
Why the hell you need to bring my name in between then.
See the date of that subject?
Does the date make any difference after 4 years even this thread will get old. Its the content and not date as far as content is concerned even you are no more than a novice.
also My question was on topic and directly related to 8051
PCB design is not off topic it has been discussed several times you always need a PCB to make a 8051 work and when FPGA CPLD 82xx 74xxx Keyboards LCD etc etc can be discussed why can't PCB.
At that time I migrated from PIC to 8051 OK.
I dont think that makes any sense you were migrating from PIC to 8051 but me being a mechanical engg. things are even more difficult.
Now may I ask you why do you post here half baked QUESTIONS
Why dont you cook them up I don't think my query was half baked. refer http://www.8052.com/forum/read.phtml?id=70398
ASK anyone this is a professional forum and not a teaching ground for newcommers if you post silly question get ready for FLAIRS OK
First of all I dont need to ask anyone as far as the forum nature is concerned weather professional or not you better see your question here it is http://www.8052.com/forum/read.phtml?id=6427
now you decide how professional this is.
I dont spy other people posts to let them down for no reasons . Are you that much FREE??.
Did think it was spying, than everyone does it who hits the search button. Glad to read that EXPERT like you is down. I am very much FREE do you have a job offer for me???

PS: The question that you put is ULTRA ULTRA basic
HERE it IS once AGAIN http://www.8052.com/forum/read.phtml?id=6427
