Configuration

Software

All parameters are optional. They all have a defined default value.

The Art-Net configuration is stored on the sdcard in the file "artnet.txt".

Parameter name  Description
 net
 Bits 14-8 of the 15 bit Port-Address are encoded into the bottom 7 bits of this field. (default = 0)
 subnet
 Bits 7-4 of the 15 bit Port-Address are encoded into the bottom 4 bits of this field. (default = 0)
 universe
 Bits 3-0 of the 15 bit Port-Address. (default = 0)
 output  dmx (default) / spi (WS28xx configuration) / mon (real-time DMX monitor, WiFi version only)  
 use_timecode  0 (default) / 1 (display the TimeCode in the upper right corner)
 use_timesync 0 (default) / 1 (display the TimeSync in the upper right corner)
 enable_rdm 0 (default) / 1 (Enable RDM mode)
 short_name Default = 'AvV Art-Net Node'
 long_name Default = 'Raspberry Pi Art-Net 3 Node http://www.raspberrypi-dmx.org'
 manufacturer_id Default = 7FF0 (RESERVED FOR PROTOTYPING/EXPERIMENTAL USE ONLY)
 oem_value Default = 20E0 (OemArtRelay)
 network_data_loss_timeout The time in seconds when output will be stopped stopped or blackout. Maximum = 255. (default = 10). 0 = disabled.
 disable_merge_timeout 0 (default) / 1

Example:
output=spi

The WS28xx configuration is stored on the sdcard in the file "devices.txt".

Example:
led_type=WS2812B
led_count=144


The DMX configuration is stored on the sdcard in the file "params.txt".

Parameter name
 Description
 dmxsend_break_time  DMX output Break time in microseconds. Valid range is 92 to 176. (default = 92)
 dmxsend_mab_time  DMX output Mark After Break time in microseconds. Valid range is 12 to 1000000. (default = 12)
 dmxsend_refresh_rate  DMX output rate in packets per second. 0 for fastest rate possible. (default = 40)

Example:
#dmxsend_break_time=
#dmxsend_mab_time=
dmxsend_refresh_rate=0
