Re: voltage divider circuit
You tested your circuit with breadboard carefully. But you took in account the values of source and load resistor?
When you check you circuit with breadboard, did you measure your output with load condition? If did, I am sure that the result on PCB or breadboard is...
I'm a new learner of writing driver, but I using WIN XP OS and I don't have WIN XP DDK.
I've WIN 2000 DDK, but i don't know what difference between the twos.
Does anyone know whether I can use WIN 2000 DDK in writing driver in Win XP? or where I can get WINXP DDK?
Thanks in advance.
Re: Filter Design
After all, you should read this book "Network Theory and Filter Design" and "Continuous Time Active Filter Design", but the later is better and easy to understand. If you read the second book, you should read completely from beginning to end.
I used to read the later book to...
Sorry if I post this in wrong place.
Does anyone know where I can buy parts (Eg. An2121, PDUSB12...).
Because I live in VietNam and VietNam market don't buy many part as other contries. Another reason is I can't order part I need from manufacturers due to they don't deliver part with small...
I agree with you this point. But, choosing between current or voltage not only depend on which kind of application, but also which freq. you want to design.
Eg.: when you want to design a high freq. communication system, it's obviously that voltage amplitude is quite small; but for some certain...
I have SoftIce program using to writing driver in Window, but I don't know where I have to start.
Becauce it relates to many aspects, even architecture & operation of operating system. So, do I need study and have knowledge about these aspects before I begin wrting driver.
If anyboby...
You transmitted and received successfully from your series port, but how you set up your series port rate?
Baud rate of series port should be equal to baud rate of uC. If you set up series port rate too high, you can transmit or receive data at MAX232, but you uC may not receive? So, you should...
I think you want to get the address of parallel port while programming?
If so, you get this by VB via using API function that Window provide. If you want to know more how to use API function in VB, you can find books about Advanced VB programming
I think choosing freq. of crystal is not inportant. It's more important that at what baud rate you want to communicate with series port. Once you determined baud rate you need, then you can choose what crystal should be used.
Further detail about how to calculate baud rate can be found in some...
I think you should read some book first. There are some book introducing many basic concepts, practical aspects of RF design practical circuit design.
You can find in books: "Fundamental of RF Circuit Design with low noise oscillators" and "RF Design Guide System, Circuit, and Equations"
Re: class c
I think you should find this in many book about designing RF circuits. Such as " Fundermentals of RF circuit design" or some book. I don't remember now but I will send the address to you later.
Re: USB beginner
So, you already have this ebook "USB design by example".
Could you share it to me!!!
Now, I had other book about USB, but they almost help me in understanding USB protocol. And I'm vey confused where I can find a full ilustrated book in design a USB device.
And I also lack of...
I'm sorry if i post this at wrong place.
I truly need schematic of Proview monitor, but I can't find it anywhere. Do anybody instruct me where to get it.
Thanks and expecting your reply.
Moved to service manuals
