From package/directfb/directfb.mk:

...
ifeq ($(BR2_PACKAGE_DIRECTFB_MULTI),y)
DIRECTFB_CONF_OPTS += --enable-multi --enable-fusion
DIRECTFB_DEPENDENCIES += linux-fusion
endif
...

Disable DIRECTFB_MULTI, rebuild directfb and try again (just a guess, not tested)...

Regards,
Peter

[Buildroot] setting up directfb for a raspberry pi + waveshare32b display

[Lou Crittenden]

Got it to work after about a 2 hour rebuild with make clean all and
removing the said option. You guessed properly. I also had to use fb1
instead of fb0. I would love to use fb1 as the default framebuffer.

[Buildroot] setting up directfb for a raspberry pi + waveshare32b display

[Lou Crittenden]

on the df_knuckles demo, the touch screen works, but it appears that I have
reverse the axes somehow, as it appears that if I move my finger left to
right, the skull moves up and down and vice versa.

[Buildroot] setting up directfb for a raspberry pi + waveshare32b display

[Lou Crittenden]

I can also confirm that the axes are reversed on the df_bltload by running:
df_bltload --dfb:fbdev=/dev/fb1.

I was thinking I could make an ads7846 configuration file at
/etc/modprobe.d/00-ads7846.conf (like we did with the waveshare32b) to also
include the ads7846 touchscreen device with reversed axes.

For starters, the contents will be:

options ads7846_device debug=1 cs=1 speed=2000000 model=7846 x_min=230
x_max=3900 y_min=200 y_max=3700 x_plate_ohms=80 pressure_max=255
gpio_pendown=23 keep_vref_on=1

I will see how this goes and edit accordingly.

Disregard that!! I remember now making the /etc/init.d/s30fbtft script and
I found the part that has the "swap_xy=0" and am changing it to
"swap_xy=1", and doing the tweaks from there.

[Buildroot] setting up directfb for a raspberry pi + waveshare32b display

[Zygmunt Ptak]

Hi Lou,
Do you want to use qt quick with directfb?
I have waveshare 4 inch (A), and for now without any success on this.
Everything with OGL is rendered on HDMI output,
so I think it's not possible to use fbdev with  qt quick. Code with widgets
works good.
I you will have any success on this, I would be greatful for any info.
Regards
Zygmunt

Qt quick looks promising to use as an interface for directfb, although I
never have gotten into it. You mentioning it to me is the first time I have
heard of it. I watched a demo on how to create an interface here
https://www.youtube.com/watch?v=_6_F6Kpjd-Q. By the looks of what I saw in
the vid, it looks promising, but of course that guy made it look easy.

Do you know what framebuffer you are outputting to? Mine is /dev/fb1.
/dev/fb0 is the hdmi/video out, assuming you are using a raspberry pi.

Well, I swapped the axes by changing swap_xy=0 to swap_xy=1 and while it
swapped the axes, I am having an issue where the y-axis is inverted, so
when I move my finger up and down the screen (it is in landscape), the
arrow moves the opposite. If I move the arrow left and right along the
x-axis, it moves properly. How do I fix that y-axis?

[Buildroot] setting up directfb for a raspberry pi + waveshare32b display

[Lou Crittenden]

I tried running them and got an error stating it can't find /dev/fusion0 or
/dev/fusion/0 after running any of the df_knuckles --dfb commands with the
exception of the help command.

Did you have to create new device nodes and directories? I had to using
mkdir /dev/fusion
mkdir /dev/fusion0

then made the device nodes with these commands:

mknod /dev/fusion/0 c 253 0
mknod /dev/fusion/0 c 252 0
mknod /dev/fusion0 c 252 0
mknod /dev/fusion0 c 253 0

I then ran
$ df_knuckles --dfb:fbdev=/dev/fb1
$ df_dok --dfb:fbdev=/dev/fb1
$ df_cpuload --dfb:fbdev=/dev/fb1

both as root and as another user and I get:
(!) Fusion/Init: could not enter world 0! not a typewriter

I have no idea what that means. Other people have gotten the error as well,
but haven't had solutions, as per various searches.

Just a quick test:

$ df_knuckles --dfb:help
$ df_knuckles --dfb:fbdev=/dev/fb1
$ df_dok --dfb:fbdev=/dev/fb1
$ df_cpuload --dfb:fbdev=/dev/fb1

work for me...

$ df_drivertest  --dfb:fbdev=/dev/fb1
df_drivertest.c <97>:
        (#) DirectFBError [dfb->CreateSurface( dfb, &dsc, &primary )]: The requested operation or an argument is (currently) not supported

failes..

Peter

[Buildroot] setting up directfb for a raspberry pi + waveshare32b display

[Lou Crittenden]

Hi all. I have a buildroot setup running on a raspberry pi model b+ and a
waveshare32b 3.2" display and was able to get the system to work with the
display thanks to peter seiderer's awesome patch that builds the fbtft
drivers for buildroot, but I now would like to set up directfb to work on
this setup. Directfb built nicely, along with sdl and qt5 (I'm setting up
the framework for a gui on a buildroot based media player), but I cannot
get anything to work on directfb. I run the command "df_drivertest" that
tests for the driver, and it gives a

(#) DirectFBError [dfb->CreateSurface( dfb, &dsc, &primary )]: The
requested operation or an argument is (currently)Not
supported.

The same thing happens when I try to run any of their directfb demos.
I went on their site, directfb.org, and a lot of the links that would
help are dead


I want to use a setup lighter than xorg and supports touchscreen for a
gui on a multimedia player I am working on.
