Multichannel USB Audio Class 2.0 linux Driver
Hello, I should start developing a multichannel audio to usb board and I think that the "xCORE-200 Multichannel Audio Platform" (XK-AUDIO-216-MC-AB; https://www.xmos.com/support/boards?product=18334 ) is the reference for my project. I am worried about driver availability for linux (e.g. d...

"extern" keyword for multiple return value function
I use to put "extern" keyword for function protoype in header files. Not a big issue but it seems not to be accepted for xc functions returning multiple values. example .xc file: int SimpleFunction(void) { return 1; } { int, int, int} MultipleReturnValueFunction(void) { return { 1, 2, 3 };...

Re: Efficient YUV422 to RGB565 on L16
Don't know if -O3 optimization is smart enough to recognize that you are evaluating 298 * C(Y) three times and D(U), E(V) twice. May be using a variable for those partial result saves some clock...

Re: NeoPixel LEDs on startKIT
Hi i'm a fan of those RGB leds with embedded rgb dimmer (WS2812). A logarithmic look up table is necessary to have a correct brightness sensation. That is the test code I used. It makes a nice wave effect. #include <platform.h> #include <xs1.h> #include <stdio.h> #include <print.h> #include <math.h>...

Segher is right: the first set of macro is not for reentrant/recursive functions.
But there is also a set which stores local variables

Coroutines: a "must know" for programmers (according to me)
Some years ago I found a document by Simon Tatham with a coroutine.h source conaining a set C macros to make cooperative routines. http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html I became a fan of those macros that let you make a sort of multi tasking. No need to waste precious real time...
