ARM9 , OMAP And BeagleBoard in India

Vikas Patial — Wed, 07 Oct 2009 21:47:41 +0000

Currently i am working on a ARM9 based platform and found out that in India its really hard to get by ARM9 which is above 500 Mhz and costs < Rs 10k. ARM7 TDMI is whats easily available and after having some fun with it , it was found to be highly underpowered.

So if anyone looking for a ARM9 Based Platform in India get a Beagle Board ... Its what i call Awesome for the price and performance. To get it you can go through either Indian vendors who overcharge and fleece as usual or Get it from Sparkfun(Awesome Service) where i got it from. Digikey also sells it but charges a hell of a lot of shipping. So if you are looking around source from US and dont waste time like i did looking locally and getting frustrated.

149 USD + 9 USD USPS = 160 USD ( approx Rs 7500 as of the time of posting ). The cables , SD card etc all can be bought for < Rs 500 locally.

While Indian vendors like Cranes etc are charging like Rs 13000. Why dont we have shops like spark fun in India .

You can also buy from IDA Systems for Rs 9000 http://www.idasystems.net/beagle_board.

Arduino Hex Uploader and Programmer

Here is something which might be useful to people who program Ardunio not using the IDE , like me. I use AVG GCC to develop code and use this to upload to Arduino.

Some features over the default Gui available on the Arduino.cc site.

AutoReset – RTS AND DTR are reset ( No more pressing reset )
AutoDetect Arduino when connected and removed ( USB COM port )
Remembers Last Settings
Very easy to use

Arduino ATMega8 Bootloader 2 Second Autoreset

Vikas Patial — Mon, 17 Aug 2009 22:33:48 +0000

Here is a Arduino Boot loader for ATMega8 with about 2 Second Reset Timeout ( Since all boards now support autoreset ) . Well the source code comes with arduino but you have to use a gcc < 4.0 to get it compiled under 1 KB.

Some how i found it a headache to compile under windows , so here is the compiled version so that you dont have to go though that.

So you can just download here …

External Crystal 16 Mhz , 2 Second Timeout with 19200 as Baud.
