Most settings/options can be understood from reading the hppm_py/hppm_proc_py.ini configuration file. The Raspberry Pi code only supports LPD8806 at this time. hppm_py/ contains python code. You can push OSC to it or use it alone with the GST module to get frequency data. It can push via TCP, OSC, or serial. hppm_raspi/ contains C code. It takes TCP input and pushes it to LPD8806 via spidev. hppm_ard/ contains Arudino code. It takes serial input and push it to LPD8806 or WS2801. hppm_live/ contains MAX4Live files and a Live project. It pushes OSC data.
