how to use GDAUIO?

[cheater]

Hi ugfx-Team,

i have the  http://www.mikroe.com/mikromedia/7/stm32f4/. I already got ugfx working with chibios.

The next big deal will be sounds. I cant even compile the 'play-vs1053' demo.

It gives me this error:

../../uGFX/drivers/gaudio/vs1053/gaudio_play_vs1053.c:184:1: error: unknown type name 'GTimer' several times.

this is my makefile, i edited some lines like the wiki mentioned.

Ok, the demo compiles, i had to add GFX_USE_GTIMER to the gfxconf.

 

[Joel Bodenmann]

This is strange. The rules set of the GAUDIO module should automatically turn GFX_USE_GTIMER on if you enable the GAUDIO module:

#if GFX_USE_GAUDIO
	#if GFX_USE_GEVENT && !GFX_USE_GTIMER
		#if GFX_DISPLAY_RULE_WARNINGS
			#warning "GAUDIO: GFX_USE_GTIMER is required if GFX_USE_GAUDIO and GFX_USE_GEVENT are TRUE. It has been turned on for you."
		#endif
		#undef GFX_USE_GTIMER
		#define	GFX_USE_GTIMER		TRUE
	#endif
#endif

Is there any way you can reproduce this problem?

[cheater]

Hi Joel, if  #define GFX_USE_GTIMER  TRUE is missing, i got the error just out of the box.

 

But i have another Problem now, i cant access the sd-card. I added #define GFILE_NEED_FATFS        TRUE but then i get this:

any hints for me?

We will investigate - this shouldn't happen. The GAUDIO module is supposed to automatically enable the GTIMER module and just showing a compilation warning.

The file /src/gfile/gfile_fatfs_diskio_chibios.c implements a default disk interface that works with most ChibiOS/RT setups. You might need to modify it to your needs in case of you are using other card interfaces.
You will still have to enable all the required stuff in ChibiOS/RT itself (halconf.h and mcuconf.h files). µGFX can't enable the MMC or SDIO interfaces and other required stuff for you in the ChibiOS/RT files.
We strongly recommend getting your SD-Card up and running in a bare ChibiOS/RT project before you slap µGFX on top of it. That's way easier to debug. As soon as your SD-Card is working with ChibiOS/RT itself it will most likely just work out of the box with the GFILE module of µGFX.

I hope that helps
