I like to add that the long awaited "Quite Universal Circuit Simulator"
with graphical user interface (GUI) or also known as Qucs is now on
internet downloadable in its newest version 0.0.19.
You can use it to test Digital and Analog Electronic circuits complete
with VHDL programming capbilities!
I haven't tested it yet but according to the User reviews it recieved all
5 stars !!!
https://sourceforge.net/projects/qucs/?source=typ_redirect
I can't wait to test it myself!

Very nice work and explanation. I do hope that you will come out with a write up on how to program uController ICs used on audio/video systems, especially when these are no longer available from the manufacturers, but ICs are available for purchase. Thanks for sharing! Please keep it up!

Hi!
I would have a question for you Mr. Hafiz:
How can readers use this article for repairing?
I wont be a party breaker, I'm all-days do uC programming, decoding, hacking, cracking stuff deep in and I understand your learning but I don't understand how could peoples who search for his/her repairing stuff find a solution using this uC tutorial?
I think you should give as/them a more practical tutorial how to solve a problem in an electronic device even with a uC.
Sorry for my somehow negative comment.
Maybe you can write a tutorial how to repair a device if the uC is in trouble, or how to check the functions of the uC or maybe how to get out the data from a protected uC to reuse it on a device with a same defective uC or how to use a logic analyzer or scope to trace some data to see how the uC communicate with the other parts on the PCB or whatever what can be used as a repairing tool/solution...
You have access to some data maybe on your University what is hard to find, share that if it is legal with as, you also have equipment's what is hard to see in small all-days service centers, share knowledge about them how to use them, compare some of them with a cheaper tool etc...
C and ASM is a bit hard for peoples who just start to learning uC stuff, show some advice to Bascom ( the good old Basic 🙂 ) programming language, maybe peoples will more love the uC world then.
Bascom is a very nice tool for beginners who wish to get some experience in the world of uC from Atmel but also a robust tool for making robust applications based on the ATMEL uC's.
Otherwise, I like your writing and it is nice, step by step organized.
Well done.
Please don't hate my comment, I wont be an angry bird here.
Keep up and we will see what would happen.

Thank you Hafiz.
I understand that you like the free KEIL software to program in C or C++
or in Assembly. But you are not at all limited to only these 2 options
because it is also possible to use the BASCOM-8051 Compiler. It is
probably much easier to learn for many readers and is also very fast and
free! (with only some code size limitations in the free edition). See:

http://www.mcselec.com/index.php?page=shop.product_details&flypage=shop.flypage&product_id=87&option=com_
phpshop&Itemid=1

And because - in this line of Jestine's programming articles -
I previously wrote an intro on programming FPGA's in VHDL, I like to add that there is also a completely new and free program called DEEDS that can be downloaded at this link (not tested yet):

http://www.esng.dibe.unige.it/deeds/Downloads.htm
(about 20 MB).
Cheers!
