Just because of all those people asking how to reinvent the wheel with SIO stuff, here's my sources for a sio driver PRX...they proved to work very well even with high and non-standard baudrates notwithstanding they're so simple, in fact they do work with my MIDI hack. I post this so a "standar...

Hi rus_pa!!
Are you loading the prx in kernel mode?? No HW mess-up allowed in user-mode...are you managing k1 stuff?? Have you the latest pspsdk environment??
Try all this and then try downloading from svn the latest
pspsdk.h
pspsyscon.h
(and related libs...)

see you soon

Well, you don't need to resize a texture at all, because you will always map it on a poly....if you want to reduce texture dimensions once loaded before entring in critical loops, long elaboration time should not be an issue...if you still wish to do such a thing you should study the renderTarget de...

Well, I don't think chache sync would be an issue if our elaborations on ME are big enough...if we do image processing/sound generation/(put your beefy media task here) on ME, and hence process banks of 300Kb at a time, chache invalidation would not be the bottleneck...I would never bother to put my...

The general structure of such a library should be something like this: 1) registration of needed services (each "service" structure has an ID, a function pointer to the service implementor itself, a priority and maybe a little contextualization data) Once registration data is stored, no op...

@J.F. Little OT: I tried to connect an IR sensor to the mic line of PSP to allow a program grab certain ir codes and it -somhow- works...but it's not very elegant to waste cpu cycles grabbing mic signal and converting it "raw". If we could hack the interrupt manager properly, we could forc...

WOW, they're wonderful....D'oh.....not too bad, i like do myself things in McGuyver-style!!!

Oh, thanks...i will correct this... I know the name of the acid in my language, but i didn't know how to translate....Thanks again

Again with an hardware post....the last one, i promise!!! :))) Deniska will be happy to see this: i made a little demonstration of how to connect a GPS without serial connection to the psp. I'm in no case responsible of any damage this will cause to your hardware.... http://www.ecando.it/files/GPS_h...

For the "what could I connect to my PSP today?"-serie, i managed to connect a standard MIDI device to my PSP-Phat and capture midi messages. This is quite simple, because if you don't count the physical layer (that involves current-loop and optoisolators) and non standard bitrate (31.25 Kb...

Connector issues???

Don't know if someone is interested since this is a software developing forum, but i asked Tyranid and he said "why not?". So here it is a small guide on how to create your own SIO connector yourself without having to tear apart your remote. It's intended for PSP Phat, but i think the proc...

mmhhhh.....seems like an unsatisfied skype user to me... :)))))

Don't know if i remember right but...every license ever made is nothing but a personal agreement between parts (developer[s] and user[s] in a one to one fashion) that is implicitly accepted in the moment you use the software, and is void if one of the two parts does not respect license terms. In add...

good point! I forgot there are people from the whole world here...in my country the 16f84 is widespread and cheap because of its very large use in seca-satellite era :)))) Anyway the problem remains the same: we still need to power supply the keyboard... it would be nice to cut off leds and complete...

waiting for the chatpad hack to work, let's get back to the ps2 keyboard thing... just to avoid repeating the basics (and actually, to give credit) i'm not writing an howto on my own, but i will redirect you to this link: http://www.trash.net/~luethi/microchip/projects/keyboard/v1xx/keyboard_v1xx.ht...

MAYBE I GOT IT!! 3 or 4 months ago i bought an XBOX360 chatpad (i don't own an XBOX, let's say it is an hobby of mine to disassemble controllers) and obviously tried to reverse-eng it using my pc sound card as an oscilloscope. I gave up because of the bitrate being too fast for the soundcard to hold...

don't know how the PSP hardware works and if it's software-tweakable (i own a phat), but if you search on the net, there are many circuits to do the conversion you say... you can search for YUV to RGB, since Y pB pR is a somehow non-linear version of YUV, but if you're not too deep into it, they're ...

Also can you post the code, and the schematic well...ok, just let me put toghether an howto (i just did it for myself..)...anyway i did not mention i have a phat PSP...as long as you own the serial connector, nothing should change Why are you trying to convert 2.5 Volts to 5 Volts? To connect a PS2...

To return to main topic...I managed to get a PS2 keybord work with PSP through SIO utilizing 1) batteries (i tried utilizing a MAX619 to elevate tension from 2.5 to 5V, but both PSP's SIO and MAX619 are not willing to feed enough current) 2) a homemade connector (not based on remote controller cord)...

Cool!! Really. Unfortunately I don't think I could be of help since with ME hardware, I'm still experimentig basics... However, from what i can see(and given my experience on ME i could probably be mistaken) , i don't think that making ME code capable of calling usermode code will be of interest. In...

Just to reply @Art... i've sectioned PSP's remote :) and even if it's all thight and integrate SMD technology, i can guess that the fourth ring of the audio connector (that SOCOM mic uses) doesn't go directly to the "serial" connector, but is preamplified (we could do as well in a DIY mic ...

---------------- if you're not interested in anything else than PSP-programming-related arguments, please skip until the more constructive argument . ---------------- 'GPGPU' sounds fun on PSP, I did some on PS2 for interpolation of some 8bit values and it was incredibly fast, but I never found a wa...

...demonstrating what an ass he is... Look poeple!! Mr macho-man is back!! If it can make you feel better i can post 1193 bullshits on this forum...after that will you treat me with a little respect?? This is surely maturity!! Look at the GPGPU examples currently out I could tell you you're a compl...

@wally Finally a person I can talk with! Thanks for your care. I wished to write a demo, but my time was sooo small...so i gave my idea to the community...who didn't appreciate it. After all, the criticisms had the effect to push me into the challenge and try to code something. Let's do this way: i'...

What's the problem mr smart man? Do YOU are a REAL developer? Do YOU have a realistic goal? Then go for it! (and don't annoy me: all of your replies to me are simply pointless) GPGPU _IS NOT_ something you CAN do ONLY if you have beefy hardware, BUT a trick to speed up things when you DON'T HAVE IT....

@adrahil Oh and all that of course without any display - since GE kind of is one of the only ways to access the display :) Render-to-texture is a way to "draw" without display anything. I've not tryed this way mayself, but i think that a glance at the pspsdk example is enough to tell this ...

just read topics instead of blindly-reply:

...and hence improve response time of -for instance- correlation and transformation algorithms (i.e.:faster OCR, realtime voice recognition, etc...)

I'm not even sure that's fast enough to justify doing it there GPUs are highly optimized to do SIMD (Single Instruction on Multiple Data) stuff. If you can achieve a good parallelism between CPU and GPU (i.e. if you can feed GPU with non-blocking calls) then the trick helps even if GPU is slower th...

My first thesis was on GPGPU - "General Purpose computation on Graphical Processing Units" - i.e. the answer to the question: << How could I trick a Graphical Processor and make it think it is computing Doom 3's reflection while actually it is accelerating serious computations (not necessa...
