+# Decoder for oma battery powered roller blind motor controller
+# Tested with blind motor with electronic limit switch. Mechanical limit 
+# switch motors not tested.
+# Instructions (LKC040902 ver 1.0) reference motors C-C16/C-C17.
+
+# The device tested is model 8C-C18-DC-WA-A101 5 channels
+# 433.92MHz
+# https://www.omaautomation.com/
+# FCC ID: Unknown
+
+# Note. There is another controller of similar apearance, which has 
+# programmable date/time functions, which uses a different (incompatable)
+# protocol. 
+
+# User manual: LKC040902 ver 1.0 (hardcopy)
+
+# FCC ID: Unknown
+
+# I have tested commands for blind up, blind stop and blind down. 
+
+# Short pulses have been found to work between 400 to 350 us, with long pulses
+# twice that.
+
+# Schema of signal is   <2 byte command>
+#                       <7 byte controller address>
+#                       <1 byte 1's compliment of channel number>
+# Up and down commands are sent as a pair of repeated commands.
+# Stop command is sent as a single repeated command.
+# The number of repeats received is quite variable, usually around 10.
+
+# Channel number is 1's complement of the eigth byte. Thus 0xf = channel 0
+#                                                          0xe = channel 1
+#                                                          ...
+#                                                          0x0 = channel 15    
+
+# Up commands are:
+#   Burst of about 6 repeats of:                <ee><7 byte controler address><1 byte channel>
+#   followed by a burst of about 6 repeats of:  <e1><7 byte controler address><1 byte channel>
+
+# Stop commands are:    
+#   Burst of about 6 repeats of:                <aa><7 byte controler address><1 byte channel>
+
+# Down commands are:
+#   Burst of about 6 repeats of:                <cc><7 byte controler address><1 byte channel>
+#   followed by a burst of about 6 repeats of:  <c3><7 byte controler address><1 byte channel>
