[chibios.c not compiled in Keil]

I think that this seems to be a ChibiOS/RT + Keil problem where I cannot help. Please ask in the ChibiOS/RT community forum.

I'll be more than happy to help once you hit other uGFX problems.

Thank you, Tectu. You helped me a lot.

'implicit declaration' warning dont go away. I didnt write any includes manually.

Add this string

np = (void*)gfxAlloc((size_t)newsz);

Error is gone. But three new errors add

compiling chibios.c...

You are missing the path to .\ext\ugfx\src\gos.

Make sure that you add .\ext\ugfx\src\gos\chibios.c to your sources as well.

Add to path, no result

Thank you, Tectu.

Second error was corrected. Definition of size_t type:

#if defined(__cplusplus) || !defined(__STRICT_ANSI__)
 /* unconditional in C++ and non-strict C for consistency of debug info */
  typedef unsigned int size_t;
#elif !defined(__size_t)
  #define __size_t 1
  typedef unsigned int size_t;   /* others (e.g. ) also define */
   /* the unsigned integral type of the result of the sizeof operator. */
#endif

[chibios.c not compiled in Keil]

Hi everybody,

I have a problem with a compilation project in Keil. File chibios.c not compiled, Keil produces 2 errors:

in

void *gfxRealloc(void *ptr, size_t oldsz, size_t newsz)
{
	void *np;
	if (newsz <= oldsz)
		return ptr;
	np = gfxAlloc(newsz); // 63 string string with error
	if (!np)
		return 0;
	if (oldsz)
		memcpy(np, ptr, oldsz);
	return np;
}

error:

ext\ugfx\src\gos\chibios.c(63): warning:  #223-D: function "chHeapAlloc" declared implicitly
ext\ugfx\src\gos\chibios.c(63): error:  #513: a value of type "int" cannot be assigned to an entity of type "void *"

second

gfxThreadHandle gfxThreadCreate(void *stackarea, size_t stacksz, threadpriority_t prio, DECLARE_THREAD_FUNCTION((*fn),p), void *param)
{
	if (!stackarea) {
		if (!stacksz) stacksz = 256;
		return chThdCreateFromHeap(0, stacksz, prio, fn, param); //156 string with error
	}

	if (!stacksz)
		return 0;

	return chThdCreateStatic(stackarea, stacksz, prio, fn, param);
}

error

ext\ugfx\src\gos\chibios.c(156): warning:  #223-D: function "chThdCreateFromHeap" declared implicitly
ext\ugfx\src\gos\chibios.c(156): error:  #120: return value type does not match the function type

Chibios without ugfx work fine. Please help me.

[Using uGFX on bare metal]

Ok, Tectu ask me, but i can't send PM, so I have to answer this way - here is my current status:

My plan is to create project using Em::Blocks IDE for STM32 Camera rev. 3.1 board with uGFX. Currently i've created project, added ugfx and created gos/baremetal.c and gos/baremetal.h - actually based on Chibios template. I've created gfxconf.h and set new definition GFX_USE_OS_BAREMETAL. Now i'm resolving compilation errors because of the new system definition (i'm totally new with mutexes, semaphores, etc... so please be patient)

Pablo2048

Hi Pablo2048. I want make project with STM32F103 and SSD1289 + uGFX (on bare metal). Wanted to know what the progress in your work?
