hi

when I "make led-image-viewer" command I receive this message :

/usr/bin/ld: warning: libjpeg.so.8, needed by /usr/lib/libGraphicsMagick.so, may conflict with libjpeg.so.62

Apparently led-image-viewer works but any GIF is show on the panel

please help me

hzeller commented 8 years ago

This is only a warning, so things should work fine.

Your sentence is not quite clear: you tried and show images such as PNG or JPEG but then GIF didn't work ?

dennys78 commented 8 years ago

It does not work any images... my procedure is this:

git clone https://github.com/hzeller/rpi-rgb-led-matrix.git

edit Makefile and correct in /lib HARDWARE_DESC?=adafruit-hat uncomment DEFINES+=-DADAFRUIT_RGBMATRIX_HAT_PWM

cd ..

make (compile but not appare executable led-matrix)

cd utils

make led-image-viewer and appear 1 warning but I seems work

when lunch #./led-image-viewer -c1 pesci.gif
appear : Load images... Display. But nothing on the panel :( :( :(

Did you confirm that the regular demos work with your Adafruit PWM hardware modification ?

dennys78 commented 8 years ago

no don't work

hzeller commented 8 years ago

Then you first need to make sure that that is working. The README has a lot of information regarding troubleshooting the Adafruit modifications. For instance, did you disable the sound system ?

dennys78 commented 8 years ago

I will try with this command :

./led-image-viewer --led-no-hardware-pulse -C -c1 pesci.gif

but nothing

dennys78 commented 8 years ago

It's possible send me a version correctly compiled for raspberry pi 3 ??!? Or use another system?!!

hzeller commented 8 years ago

This has nothing to do with the Raspberry Pi 3 - the library compiles fine there and works. You have something in your electrical set-up that is not working. Maybe the bridge you had to solder to use the HAT PWM setting is not working properly. You need to systematically rule out the mistakes.

hzeller commented 8 years ago

Haven't heard anything, I presume you figured it out.

dennys78 commented 8 years ago

Great the bridge not working properly!!! Now all ok. Thank for the support!!!!!
