Microcontroller and Success : A true Story


At the year of 2008 , I found an advertisement in Appliance magazine about a free kit from a Microcontroller company called Renesas.

I really wanted to get this development kit. It was dedicated to motor control. I registered for this kit but unfortunately it was available only in USA and Canada.

However, my email was added in the company's clients database. Next, the company started a design contest at the same year called Renesas HTS Design Contest 2008.



The company invited me to participate in this design contest. It was a world wide contest which included shipment of free development kit to each eligible participant.

First I was admired by the idea itself of receiving a free development kit for the contest. I wanted to have this kit to learn more about Embedded C programming and to learn the Renesas technology which was new to me until that time.


To be eligible to receive the kit, there was a short demo for the company's other educational boards over a Virtual Lab environment. Then you are asked few questions to qualify for receiving the kit.

I passed through the stages of qualification and waited to receive the kit. When I received it I started to develop my design right away.




The company made a very good idea for improving the challenge through the launch of a forum for the challenge.

Each participant posted the idea of his entry and provided some technical details about it . This idea was very helpful and motivational. Any visitor or another participant can see your posted details and get admired with it or comment on it.





My design was a Multichannel Oscilloscope. The idea was very simple. I made the analog signals read by the analog-to-digital converter of the Microcontroller M16C ( on which the board is based )




The M16C has many A/D inputs but and there were 3 of them available in the challenge board.
The signals values were converted into digital in the Microcontroller and they were sent to a PC based client software which incorporated the display of a virtual Multichannel Oscilloscope.

This is the Renesas HEW program window

From the PC based client, the user can choose the input channel to be displayed on the virtual oscilloscope and the rate at which it is displayed.

Before the last day of the deadline of the contest I submitted the source code for the Microcontroller side (written in Embedded C ) and the source code of the PC client (written in Visual Basic.Net) .

The results of the contest were announced on Renesas DevCon 2008.

I've got the 4th honorable mention prize for my entry "Multichannel Oscilloscope".




This contest was very challenging and rewarding. Thanks to Renesas who has helped me through all this contest.

Information Disaster Recovery .

Data Recovery In Egypt

This post is not about Embedded Systems. It is about a problem that many people face it. Many people save their valuable data on their PCs and then something happens. A virus infects the MBR( Master Boot Record ) of the hard disk and all the partitions and data on that PC is not accessible. Or somebody saves his data on partitions other than the system partition but tries to setup Windows on the system partition and makes a mistake and installs Windows on the data partition. When he finds this out, He tries to get his important and valuable data but he can't.



I've seen the two examples happening to many people. When your PC contains some games or songs or some sources for some common programs , then your loss wouldn't be great.


But what if these data were collected and produced over a long period of time ?

And what if these data were precious photos and memories that you cannot get from any where and you didn't make backup for them ?

And what if you have saved your Master or PHD data on this PC without making backup ?

Fortunately, you can recover the data form your hard or flash disk even if they were formatted by mistake or their MBR is corrupted due to a Virus infection or a wrong operating system installation procedure.

Many programs can help you to get you lost data.




I myself have done this many times. Both recovering data form a hard disk which the user has installed Windows on the data partition by mistake and recovered data form a Hard Disk with a totally corrupted MBR .

If you faced this problem some day and don't know where to start from, just give me a call. I am sure I can help.
