ATMega128 has arrived!

I transfered on Friday, and this Sunday (about 11 am) I've already received the evaluation board.
Nice service, prasimax..

Now, lets try the hardware..

Sushi for breakfast

Here it is. A pack of Nori (thin, dried seaweed sheets) + rice + abon (shredded meat that has been boiled and fried). It looks messy (haha, as usual..)

But, no problem. I think we agree that practices make perfect ;D

Stupid mistakes, but nice progress. Fight!

Here is a documentation of my progress. There's a lot of troubleshooting. I hope the information below could help anyone who need it.

SIM300's evaluation board.
Status = solved.
I bought it from Jaya Plaza, Bandung, in a shop named "iwant".
Price: evaluation board = about Rp 800,000 
SIM300 = about Rp 450,000 

ATMega128's minimum system.
Status = couldn't find it in Anam or JP (Jaya Plaza).
Now I'm using ATMega32 (bought it from Anam, for about Rp 200,000)
FYI, the ATMega32 has a same minimum system with ATMega8535.

Another problem is how to download the program to the microcontroller.
I need STK200 Dongle downloader.

Status = subtituted by STK500 USB Dongle.This is great. The dongle is a USB version of programmer so I could continue using my laptop (which have no parallel port needed for STK200) to code.I bought this DT-HiQ AVR USB ISP from Anam (about Rp 200,000)

But this dongle leads me to another problem. When i try it using CodeVisionAVR 1.24.7e, it always give me an "AVRISP error leaving programming mode".
I wrote an email to the support system of innovative electronics (the one who produced this dongle), and have a suggestion not to use CVAVR version 1.24.7, because it has a bug in programmer STK500/AVRISP.

I browsed and googled, found Prasimax Mikron 123, located in Depok, near Jakarta.
Nice. I found ATMega128 + System Minimum / Development Board (Rp 350,000 + Rp 38,000 for the mailing cost).

I also found a link to download CodeVisionAVR 2.04.3a Evaluation version in Prasimax Mikron. And guess what? It works. There is no "AVRISP error leaving programming mode" error anymore.

Err, actually, while downloading the program, I found another error.
"The FLASH buffer is empty. Do you want to load a file?"

But it was happened just because I haven't compiled my source file before download it to the microcontroller :D Stupid mistake.

=

Well, that's my progress.Now I'm in process of ordering ATMega128 + Development Board from Prasimax.
Hope it will be fine at all.

Amin..

AT Command for fun

What is AT Commands?

Computers use AT commands to communicate with modems. Most communications applications, however, have a user interface that hides the AT commands from the user. [1]

AT commands can be issued via a communications application. When the software in the Nokia product has received an AT command, it responds with a message that is displayed on the screen of the used device, which can also be the mobile phone. [1]

Some AT commands are not supported by all Nokia products or by all operators. Giving a command that is not supported by the product causes an error response. Some Nokia products do not necessarily support all command parameters and using the unsupported parameters causes an error response. [1]

Simple AT Command for fun ;)
Let's play a bit using your phone! I'm using my Nokia 6120 classic, connect it with bluetooth, open a Hyperterminal. Try to type the green command on your hyperterminal.
1. To call/dial, for example phone number 085612345678
ATD085612345678;
Note: Actually, the reference said to dial ATD085612345678 (without using the semicolon ; ) but somehow my cellphone always give me a "NO CARRIER" response.
So I tried to google, and.. Tadaaa…
Just add a simple semicolon (;) and it's working. I guess the previous one tried to dial using data mode, because when it dialed the number, I saw a "phone-with-letter-D" icon on the upper right corner.
2. To send sms to phone number 085612345678
AT+CMGF=1
OK
AT+CSCS=”GSM”
OK
AT+CMGS=”085612345678”
> Hello world
// end the message by press Ctrl+Z, and then "Enter"

The AT commands above are successfully tested.

Just try it..
This is a basic knowledge for making sms gateway. And, believe me, there are so much more to try! Now you can imagine.. There's a lot of applications that you can make using the AT Commands.
Happy coding!

Are you sure this is really a STRAWBERRY pie?

Tadaaaa…..


Ahahahaha. Another weekend project. Maybe you would ask the same question…
Should strawberry pie have the color of red?

Yeah, you are right!
This is a very big mistake :p

I dunno why, but yesterday, the jelly's would not get thickened.
So as my auntie's suggestion, we agreed to give some amount of seaweed powder..
Well, I had not prepared for this. It was really an emergency situation.. 
And guess what?
At that moment, we only had a GREEN seaweed powder at home :P
That's why the color become green 
X-P

How about its taste? Mm..  
The crust is ok ^___^ a big success for me. 
But the jelly is too sweet. I prefer the previous apple pie :(

Here is the recipe.

Next time will be better?
Err.. I guess, next time will be the other kind of dessert :p
No more pie this month.

Maybe pudding or cheesecake? ;D 
Any idea?

Posting blog from my 6120 classic

At last! I found a way to photoblog via my mobile phone. Its quite
simple, more simple than i thought.
Now i'm using:
- nokia 6120 classic
- opera mini web browser
- gmail account, and
- (of course) blogspot account

I guess i also can use a wordpress account for this :)

Now i'm ready for a great holiday :D

Apple Pie Mission: Failed

So..
let me remind u that yesterday is a public holiday yesterday..
what's new for this week?

As planned before, this is the time for…
PIE!
:D
Ahahaha..

I've read couples of recipes and decide to use the apple pie's recipe. I've also watched a step-by-step video of how to make a home made pie crust. Actually, this recipe and video really help me to get a clue of what will I do.

Oh I do really love internet :)
But why… why…????
Why still I failed?? T_T

This is the result.. It taste quite good (for me :p) but.. I think everybody agree that these cups of cake are not pies.
X-P

It's okay. This is the first try. Next time should be better..
