microCmd/LM3S5632 boards assembled

 Just a little update on my play-board. The three pieces of board are manufactured, one soldered. Now I'm bringing device's peripherals to life. More pictures inside the post. Of course there are few mistakes from my side:

New pocket ARM LM3S battery device in development

You didn't miss anything. I was doing different sort of stuff last months instead of electronics.

Now I'm back in "business". Ordered few LM3S5632 chips and that forced me to create really small layout for this ARM MCU with interesting peripherals:

IR code soundcard software decoder

If you need to analyse IR signals of your infra red remotes and you don't have oscilloscope - try this windows application. You record the signal from your soundcard and the software shows you the waveform, decodes the signal. It supports RC5, SIRP, NEC, Panasonic. Code is open and the app is written in Delphi

Store and show your schematics online with CircuitBee

This service allows you to upload (for now only) KiCAD schematics file with libraries and embed them in your site/blog with zooming a panning. The creator of this web said that in the future we would create schematics in his online tool. That's what I'm waiting for years! I would like to have my electronics suite package in the cloud, always latest version and finally with all public libraries shared and instantaneously prepared for use.

USB HID rotary encoder

I collected information and code of my older project. You can connect the rotary encoder to the USB and scroll with it in the menus. It's only a proof-of-concept. Take inspiration but don't take the exactly same code :)

Interesting PIC constructions by Nicholas Sirirak

but the information on that page is useful also for developers with another platforms. There's something about Xbees, 9bit UART, RTC clock DS1307, Light dimmer.. and a lot of other useful informations and projects.

RIGOL and other things

Things are getting to move! I finished my Engineer degree, so now I hope in plenty of free time during holidays.

The RIGOL scope also arrived, so I hooked almost everything to it and studied all possible signals around me :)

Now I'm creating decoder of infrared protocol. I started this project because of need to turn on the HTPC with my infrared remote control. But after the basics I was thinking that maybe I can add support for another protocols, make the PC start impulse programmable, send infrared codes to the computer over UART, handle and program long button press, add support for different crystals and clock speeds.... :)
