APA102/SK6822 led strip + BC-216/BC-204 controller + Madrix software  how to work

The BC-216/BC-204 don't have the APA102 ic, so the firmware need be updated.
Make sure your network is ok, and set the IP address same as the BC-204/BC-216
once you firmware update, you can use the BC-216/BC-204 to test the led strip by offline
because the BC-216/BC-204 have self-test programs
please attention, the self-test programs don't have the white color
you also can use software (Xlight, mad mapper, MILIGHT, Madrix, freestyler...) to make more effect
eg: madrix
