Run Programs from SD card on Arduino with Pyxis OS!

I think a lot of people have wanted to be able to execute code on the Arduino without having to burn it to FLASH every time. And now you can. Pyxis OS allows you to execute compiled code from a uSD card. And since they're compiled, you can release your apps for the Arduino in a closed source manner if you choice or you can share the source with the world! Enjoy the 'Hello World' demo app.

How is that possible with a harvard architecture processor? You should only be able to execute from flash, not even eeprom or ram if I understood the avr properly.

@Imprezaman555 The way you're able to execute code for the SD card on a Harvard architecture chip is a Virtual CPU. Pyxis reads in the program one instruction block at a time and supports seek commands so it can process JUMPs and BRANCHes. The code is freely available for you to look over on our site.

Amazing... but not sure if the "closed source" option is great for the comunity. For me, definitely not, but is only a personal taste...

[ArduinoWill]

@pekepowah it's not close source. The VCPU that runs everything is free to download. The only closed source bit is the compiler, which you can make your own since the VCPU is right there for you to look at. And $10 for a compiler with a year of free upgrades isn't exactly a large price tag.

When are you going to release this? I need to use it the execute programs from sd card thing

[ArduinoWill]

Don't tell anyone but I've scheduled the release day for February 1, 2010. Oh and Pyxis is going to be written up by Make Magazine! Keep an eye on my page for more details on both!

I WANT ONE

[Riskteven]

An operating system for a micro controller??? I really did not think that was even possible!

Are there operating systems for the slower CISC based micro controllers like those from Microchip as well? (I mean GUI OS'es now)

[keoni29]

COOL! Can it play pong?

[vSxScopeZz]

Next accomplishment

playing minecraft classic on this XD

[TheBypasser]

woah, so slow... That's why I prefer AVRASM firmwares over a clean MCU.

[halojumprsoffical]

witch arduino are you using

mega, uno?

because im thinking of making a Arduino open source computer

[buechleinproductions]

what shields are compatible with Pyxis?

[valentekevin100]

hey man can i use the IXM Micro SD Cell for my arduino with pyxis..is it compatible with the arduino?
