Hey Everybody,

My name is Joseph Barrow and I am 14 years old. I am wondering about a project that I recently decded to undertake. I was wondering if you could interface a Mega32 chip with an LCD screen, a PS/2 keyboard, and an SD card, which is booted off of (a homebrew operating system, thinking of calling it JoeS, just for Kicks and Giggles). I just need to know if it is a plausible idea, and if you think it is, please email me with your address, and I will scan in my schematic (drawn in Magic Marker, about 6 different colors), and send it to you to edit.

Please Email me, anybody who is interested.

Joseph Barrow



Joseph,

Have you played with putting an ATmega32 onto a breadboard and building a programmer? If not and you want to get your feet wet with microcontrollers I would suggest Smiley's book and a AVR Butterfly http://www.smileymicros.com . Or just pick up an AVR Butterfly (ATmega169) and start Google searching and ask questions here or on AVRFreaks.com.

Best regards
Jim Ronald

Thank you for your suggestion,

Although, and not to sound disrespectful,I have done embedded projects before, although, never anything by my own design. My question is only asking if you think that this is a possible idea. Since I have not done anything according to my own design, I only have enough money to do it once,I am a little worried about doing a project taht has never been tested without having an expert look at it. Although the AtMega32 programmer is the first project I ever did, and it was a good learning experience.

Thank You

Joseph Barrow

I've never done anything that exuberant with an AVR but I'm sure it's
possible. The LCD screen for sure would be possible, probably the PS/2
keyboard; I've done LCD screens and smaller keypads before. Never did
anything with an SD card connected to an AVR.

Thank you,

Your suggestion was really helpful, although, do you think that it could be done with only a smaller keypad and not a full PS/2 keyboard. Every year I choose an are of interest to work on (since Age 12) and at the end of the year, I try to do a big project, in a matter of weeks. Any simpler version would be helpful. If you want me to, I can send you the schematic to look at and tell me if I could make it simpler? Email me back if you want to take a look. I know that other people have told me that they are too busy to help me with my project, and I don't want to force it onto you.. Oh, and I was thinking a text based OS with a 4/16 screen, and make it real-time. And about the SD card. Is there any other version of external memory that would be easier, maybe one that you've tried? I haven't interfaced an SD card with AVR either, but looking at different schematics, I think that I could do it. The main part is the IC that reduces 5V to
3.3, but I want to know what you think about it.

Thank you

Joseph Barrow

Hello Slok,

I think it is a plausible idea. Have you considered working with an
opensource OS, study it and then customizing it to your needs?

Hello Joseph,

I think your project is feasible although quite some work.
You might look around at AVRfreaks for routines for some of your
functions (i.e. SD/MMC, PS/2 keyboard, LCD) and combine them with
your OS (to be). Do you know about AVRX?

For some ideas in hardware have a look at a german page with some
(over here) quite popular projects (there is a button for a
translation on top of the pages, but we all know what automatic
translations are in for ;-)):
http://www.ulrichradig.de/home/index.php/avr/eth_m32_ex and
http://www.ulrichradig.de/home/index.php/avr/avr-webmodule

Greetings from Berlin, Germany
Stefan
Thank you Mr. Uderman,

Actually, that was another plan of mine. I would think that COPOS (an OS from a Cornell student, I looked at it, and it is great), or freeRTOS might work to customize, although, I like COPOS a bit better. Thank you for telling me that it should work. I have gotten positive remarks from most people about it, and hope to start it soon. ( I might ask for all the parts for Christmas.)

Thanks Again,

Joseph Barrow

Thank you Mr. Wilmer,

I enjoyed looking at those pages. It's funny, because I speak German. I lived over half my life in Heidelberg. And because you can speak German, I would like to send you a link in return. Here is Jorg Wolfram and his AVR Basic compiler. I think that this is brilliant.

Thank You
