   * [[https://github.com/zestyping/openpixelcontrol|open pixel control]]:the real deal with simulator, examples, etc.
     * this code with examples shows how to format everything for LEDScape
+=== Patches/Fixes/Gotchas ===
+  * LEDScape (at least the Geocene version of it) uses 100% CPU
+    * the issue is the DMX-over-network protocol is failing. If not using DMX then remove it
+      * comment out around line 723 of ''opc-server.c'': ''pthread_create(&g_threads.e131_server_thread.handle, NULL, e131_server_thread, NULL);''
+  * LEDScape is throwing kernel warnings in the terminal
+    * mute the warnings with edits to ''/etc/rsyslog.conf''
+      * add above the ''modules'' section of the file (toward the beginning): ''kern.=warning :omfile:/dev/null''
+      * comment out at the end of the file: ''*.emerg                         :omusrmsg:*''
+      * ''sudo systemctl restart rsyslog''
+      * //change survives reboot//
+  * for some reason ''mpg123-jack'' segfaults (most, not all the time) when LEDScape is running. Other JACK clients and the JACK server seem OK.
+  * even when the # of strands is 1, it seems many of the pins in the P8 header are not usable when LEDScape/opc-server is running. An exception is GPIO 61 which seems to work fine regardless.
