Your library is still working? Because when Im trying ./get_code then I get errors: root@multibooth:/rpi_ws281x# make all mkdir -p java/com/github/h0ru5/neopixel swig -java -package com.github.h0ru5.neopixel -outdir java/com/github/h0ru5/neopixel python/rpi_ws281x.i cc -fPIC -I"/opt/jdk1.8.0_121/include/" -I"/opt/jdk1.8.0_121/include/"/linux -c python/rpi_ws281x_wrap.c -o rpi_ws281x_wrap.o cc -shared -o librpi_ws281x.so ws2811.o dma.o pwm.o rpi_ws281x_wrap.o cc main.c librpi_ws281x.so -L. -lrpi_ws281x -Wl,-rpath='RIGIN' -o demo librpi_ws281x.so: undefined reference to mem_unlock' librpi_ws281x.so: undefined reference tounmapmem' librpi_ws281x.so: undefined reference to mem_free' librpi_ws281x.so: undefined reference tomem_lock' librpi_ws281x.so: undefined reference to mapmem' librpi_ws281x.so: undefined reference torpi_hw_detect' librpi_ws281x.so: undefined reference to pcm_pin_alt' librpi_ws281x.so: undefined reference tombox_close' librpi_ws281x.so: undefined reference to mbox_open' librpi_ws281x.so: undefined reference tomem_alloc' collect2: error: ld returned 1 exit status

Can you help me? I know last update 2 years ago.

It seems you are missing the library file for librpi_ws281x.so this repo just contains the binding code for java.

get_code.sh is/was just a terrible hackish way to get the code from here: https://github.com/jgarff/rpi_ws281x and compile it. did you run in from the subdir? It might behave terrible in terms of working directory.

sorry, wrong lead above, the ereror is related to something that changed in the rpilib - my lousy script does not pin it to a commit or tag as it should. best head over to the lib repo and get it to compile, then you can update get_code.sh accordingly (or better make it better - its painful reading the own code from years ago :rofl: )
