[Solved] Processing - Raspbian Lite with Hyperpixel

[Mag748]

Hello,

I have developed a simple Processing sketch on my windows machine. It runs great. I would like to run this sketch on my Raspberry Pi 3 with the Pimoroni Hyperpixel (https://shop.pimoroni.com/products/hyperpixel). I have configured the Hyperpixel without issue, and can run some X11 applications on it. I've installed Processing according to the documentation here: https://www.raspberrypi.org/blog/now-av ... rocessing/

When I try and run the sketch on the Pi, it just crashes. There are no error messages or anything. I have attached my .xinitrc script for your reference. (I have to zip it because the forum would not allow me to attached any other type of file.) The program seems to crash at "exec processing". As a test, I've tried the line "exec $(which xterm)" and that successfully launches xterm, so I know my X Server is operational.

Has anyone had any luck with this? Any suggestions would be appreciated.

Thanks,
Marcus

Problem solved:

The solution is to run "processing-java" instead of "processing". So the line in .xinitrc was changed to the following:

exec processing-java --sketch=/home/pi/processing/Client_API_Test_2017_10_12b --present

I had to change the backslashes in the program to forward slashes, but not a big deal. Also, library files need to be added to the ~/sketchbook/libraries folder.

See below image of the sketch running on the RPi with Hyperpixel.
