is a graveyard nowdays, but there's a lot of tutorials, etc. to get you started.

The one I posted outputs with the y axis upside down. Here's one I corrected.. probably a sloppy way to fix: float rotation; float precalc; precalc = 3.141592/180; SceCtrlData pad; sceCtrlSetSamplingMode(1); sceCtrlPeekBufferPositive(&pad, 1); jxxx= pad.Lx - 130; ...

sceCtrlReadBufferPositive(&pad, 1); xxx= pad.Lx - 130; yyy= pad.Ly - 130; rotation = atan2 (xxx,yyy) / (3.141592/180); I've tried this one, but it crashes instantly. EDIT.. no it works ;) I just forgot sceCtrlSetSamplingMode(1); sceCtrlPeekBufferP...

I tried this, point the stick straight up, and it does output zero. as I turn the nub clockwise, the degrees var goes up to about 90 degrees, but by that time, the output should be about 260 degrees. It also crashes if it gets to just under 90 degrees. by this time the nub is almost pointing left sc...

Yes :)
NVM, I forgot the conversion.. came back to delete it ;)

Hi Guys, Well I've done my homework on this one, so I hope I can find some help. This program spins a line around a point in the centre of the screen, like a clock hand moving around a clock face. The program works, but as I increment the angle from 0-360, the line makes a full circle many times, an...

Thanks, I will give it a shot :)
I'm after 360 degree circle yes.

Hi Guys,
About a year ago I found code to output an angle in degrees
from the analogue controller input, and now can't seem to find it when I'd like to use it.

Anyone know where this is? It may not have been on this forum...
Cheers, Art.

Yeah, the value of pad.button will be unique if only square is pressed.
Look at the value of pad.buttons.

Hi Guys, In nearly 4 years I don't come here blatantly releasing my apps or demos, but I'm crawling for votes in the 2009 Neoflash spaghetti coding competition. YouTube - AVEC GPS - Real Time Navigation Please vote for AVEC in the Neoflash competition if you like what you see. The entry by the due d...

The kid that connected a PS2 Dual Shock to the PSP did a dodgy hack job
with wiring straight from the buttons of one device to the other,
in my opinion, ruining both devices in the process.

Wow, I'd love to use voice recognition, thanks :)

Would love to, but I don't actually have a solution for the internal mic, or a PSP 3000.
I was having a dig at Darius for making another fairly useless post.

Yes, Suspend and Standby are in the power lib.

If you wanted to fill the entire screen, starting bottom right, then following the recursion in my head I see it first drawing all the way to the left, 480 pixels, then moving up 1 line, then drawing all the way to the right, then repeating. Yes, I started at 0,0 and it looked to do that from the t...

Old :) But I tried it on a 2008 version and it compiled and ran ok, then did this: PSP_MODULE_INFO("AVec", 0x1000, 1, 0); PSP_MAIN_THREAD_ATTR(0); PSP_MAIN_THREAD_STACK_SIZE_KB(1024); PSP_HEAP_SIZE_KB(-1024); and it breaks it ...

I'm not using anything to adjust the heap size. Should it handle up to 130560 (480x272) recursions? I found this: http://psp.jim.sh/pspsdk-doc/pspmoduleinfo_8h.html Where it looks like this: PSP_MAIN_THREAD_STACK_SIZE_KB(size_kb) unsigned int sce_newlib_stack_kb_size = (size_...

I pretty much narrowed it down to stack overflow by limiting the number of times the function can call itself. If I limit it to 1000 times, it works, and partialy fills the screen (although 1000 pixels is less than three lines on the PSP screen). Now since I can't add this line: PSP_MAIN_THREAD_STAC...

Which one of the three microphones is the normal PSP microphone?
Talkman, Go Cam, and Socom Mic all have different code to read them.

I might assume you mean the Socom since it isn't a USB device,
but have you even tried this or are you posting just for fun again?

You can check Audio Mechanica source,
furkiup source, or a sample that's around here.
It's in a huge Chotto Cam thread.

Hi Guys, It looks like Deniska has moved on to other platforms. I'm working on a vector map based GPS app: http://www.youtube.com/watch?v=ZvhbknIGrpM I have the NMEA parser used in MapThis! working on 1.50 kernel, and need to get it working under 3.xx for the slim. Does anyone have source for the gr...

Your recursion is infinite - look at these two lines: I don't follow why you say it is infinite. I forgot I hard coded the colour in those lines though.. so: floodfill(x-1, y, 0, new_color); floodfill(x+1, y, 0, new_color); Before it makes it to the same pixel again,...

Hi Guys, I'm trying to implement a 2D recursive flood fill algo found on Wikipedia in the first example here: http://en.wikipedia.org/wiki/Flood_fill I think I've implemented it right for the PSP, but it crashes when this function is called. I call it with image coordinates well inside the image are...

I've written a little demo with a sample where triangles are defined at the
start of the program with a list of vertices in big arrays.

Where is the code to create a triangle at runtime?

When I looked again I saw I missed a function "set_filenum" which checks for the highest numbered file in a folder. Still don't think any of this should be illegal in 1.50 kernel since it is modified ms dumping code. void build_path(char *output, const char *root, const char *path, int app...

Hi Guys, For my current program, I had difficulty getting it to work in 1.50 kernel mode, and found the attached code for checking & creating folders was the culprit preventing the program from starting. Is this usual for sceio commands working with Memorysticks? This code does work in usermode ...

I still didn't get the thing to work.
I assume the 64 bit integers are long long.
I got a 16Gb MS now.

thankyou :)

would you not have to also include psppower.h for the power functions???

Hi Guys, I have always used this snippet to retrieve Memory Stick space remaining I don't know how it works: void free_ms_memory() { int memd; sceIoDevctl("ms0:", 0x02425818, &pbuf, sizeof(pbuf), 0, 0); for (memd=...
