AVR development on Ubuntu Linux.

I used Mac OS X for all my AVR developments so far.I got my netbook running Ubuntu and I want to use it for AVR developement recently. It is easier to get all the tools installed as I thought. The following commands do the magic:

sudo apt-get install gcc-avr
sudo apt-get install avr-libc
sudo apt-get install avrdude

Worked like a charm:)

Atmel USB development board - Teensy.

Teensy USB development board is a low cost AVR USB developement board featuring 2 Atmel processor: AT90USB162 and AT90USB646.

The AT90USB162 model is only $19 each.

One of the highlights of this development board is its pre-loaded Teensy Loader, which can make programming your code to the board much easier. It comes with Linux, Windows and Mac OS X support too. The demo codes included USB keyboard, mouse and usb2serial, so help you making usb peripherals much faster! I would like to have them to add USB mass storage demo code:)

I didn't use any AT90USB series, but after reading the Teensy, it is quite similar to AVR 8-bit MCU in software perspective . It also supports the Arduino software development tools (Sketches).

Android Development is fun.

Hi Readers (If any), may be you found out that I didn't update very often recently. It is because I am busy with my new HTC G1, it is a pretty cool phone! I joined android market and published two free android apps so far.

1) LunarCal
it is a Chinese calendar, so may only useful for Chinese.

2) WallCal
It draws a little calendar showing month, weekdays, date on your wallpaper, it is only a workaround solution to place a widget-like thing on the android phone desktop. So once google released the API to let developers to develop desktop widget, it will be EOL:)

If you are chinese, and also have an android phone, join me @ http://forum.androidhk.com/




Hope I can get back to hardware developments very soon:)
