Has anyone here used ART-Linux yet? It's a real time Linux version from Japan and what intrigued me was the claim of 10us latency on a Pentium II. If I remember correctly Molnar's RT-Linux patches can't even manage that on current hardware. They even have kernels for Ubuntu 8.04 (but unfortunately not 8.10). http://art-linux.sourceforge.net/ http://www.linuxdevices.com/news/NS5878102799.html ...

Windows users use a thing called MPLAB, but I can't get this for Linux. Can anyone please suggest a Linux alternative? I don't nee...

I have a Compact Flash card that was used in a custom long-term datalogger that ran to battery depletion. After recovery, the card is not recognized by the disk management tools in Windows XP, Mac OSX or Ubuntu Linux. It should have data on it, and I would like to recover that data if possible. It is certain that the logger went through a marginal power state as the batteries failed, and ma...

I have a $4 TI Launchpad with a MSP430 processor. The 2553 is a little bit too new for mspdebug however. (It has a Forth flashed into it. See http://www.4e4th.eu.) Anyway I discovered that I could not use mspdebug to reflash the program unless I cheat by telling mspdebug that it is another processor. So (on a Ubuntu 10.04.4) I can reflash by sudo mspdebug --fet-force-id MSP430FG4618 r...

Up to my understanding, is it... GPP runs above all, and GPP governs DSP and GPU to do different tasks? For example generating PWM or reading ADC? And, GPP must run on some OS, like Ubuntu? Is DSPLink the library...
