Hey sorry about topic title but i dont know how to explain this problem in 1 sentence heh.. Im writing some SPI code and all code is fine except: on stdcore[1]: out port CS = XS1_PORT_1A; on stdcore[1]: out port CLK = XS1_PORT_1B; on stdcore[1]: out port SDO = XS1_PORT_1C; on stdcore[1]: out port D...

But what I understood XC1 is now "obsolete,discontinued" or however that is said. I'ts hard to get them :(

But now ports are spreaded over cores, XC1 has all four connectors for core2, if I remember correctly. Or can we use channels to control other cores port's at full speed :shock: Don't know of that. If we can, then there isn't any problems and I'll learned something new :D

And now we have "narrower" ports.. Liked on XC1 that external memory was easier to implement... Things got very difficult now.

So, I've tried many many ways to implement or redesign exists SPI codes, but no luck. Can't get to work on core 3. VS1053 is an mp3/ogg/midi codec chip http://www.sparkfun.com/commerce/product_info.php?products_id=8954 , but haven't got any luck to make it work with XC-2. As I said, connected to cor...

Well already in another post i had the idea of rendering a simple 3D scene in real time on it or draw those beutiful looking fractal images (google chaoscope) and use one of the ethernet ports on it to host a website and display it on it. What would be totally sweet is if it would raytrace render a...

leon_heller, could you check that picture link, interested to see if it's possible to do with my equipments.
edit: Works now, don't know why it didn't a minute ago.

XC does not support floating point types. Do your float maths in C functions called from XC. Or have your main program in C making calls to XC functions to do the output. You will have to cast to/from floats appropriately. But that has to happen to get onto the display anyway. Alternatively, harder...

Another question. I've modified VGA 8bpp code and want to do some maths to render graphics. I can't find solution to use sin, cos etc. operands inside XC file. Even including math includes.

Hi,
is it possible to run single "thread" at full 400 MIPS speed on some core? I'll see from MIPS chart that four thread gets 100 mips each and so on, could these join to calculate single code without threading? And sorry about my bad english ;)
