Was wandering how the hell they powered a 5v pic They? Do you mean me? :) XBox is outputting 3- 3.6v. To say the truth, according to the 16f883's datasheed, the pic works with just 2v - some milliampere. The charge pump is put there adjust comm levels or at least to feed backlight leds, i guess. Pl...

Speaking of IDEs, I'm still for netbeans...coding C/C++ with netbeans 6 is like stealing candies from a child without an arm...Eclipse was the first java based cross-platform IDE, but by now it's slow (don't tell me it isn't if you use it on a core duo II...) and generally speaking seems to be put t...

The first code i wrote is little enough to compile with free version of mikroC...it produces middle assemblies too and porting to MPLAB's C is a piece of cake. The real pain in the a** was flashing... you need a programmer with voltage control (or, like i found, a normal JDM leaving GND unconnected....

just kidding Art ;) The nokia headsets are doing something like this since 10 years old i guess...but it's done in hardware, i.e. no signal processing taken. I think it's an heavy effort (at least a waste of CPU) to sample an analog signal only to have an additional pushbutton...Anyway there are TON...

A T6 Torx driver is all that is needed to open the Xbox 360 Chatpad Luckyly i managed to open the chatpad without that tool and it opened without effort - no scratches... a small flat tool will be enough (since torx is exagonal you only need a flat screw driver little enough to fit into it... i HAT...

I'm glad to announce that i was able to reprogram ChatPad's firmware and send some strings to the PSP via SIO interface. BAD NEWS: 1) everybody willing to have the chatpad working with his PSP have to reprogram it as i'm doing...all software is freeware, but you need programmer hardware (at least an...

Ok, 3 questions maybe i could have posted in a separate thread: 1) Why not to code libraries as a prx so old compiled binaries (we cannot recompile), would work with newer keyboard driver just swapping prxs? This would only require function entry points in prx to be consistent. 2) I've completely re...

Slow down! Emulation is a good thing itself, and so it is the wonderful PSP connectivity, but I don't think the marriage between these two things will take us that far... I think that only a native PSP application can bring us enough power to use PSP as a real MIDI instrument. I'm working on it, and...

Ok, then i think I wouldn't bother doing this in hardware or using a whole media library like SDL...just optimize your load-and-resize algorythm. To do this you have to: 1) load the whole image in memory in big chunks...it's a common mistake to do unbuffered small reads: this slows down like hell 2)...

I'm not sure doing this thing of breaking the texture into chunks would be that fine. First of all you still can't write in a texture bigger than the max size (512x512 you say...), second if you want it fast you have to setup a display list (complexity for such a simple task grows) and last but not ...

No, obviously you cannot use this tecnique with image sizes that doesn't fit in hardware supported textures....somewere in this forum or in pspsdk sources you should find the maximum dimensions and formats of PSP GE textures...if you want to do image processing on large data blocks in a crytical loo...
