Set the bus control data to the preset value.
Set SW
Measure #54 and #40 with an oscilloscope as shown in the diagram. Calculate TCL1 and TCL2.
Set the bus control data to the preset value.
Set SW
Set the unicolor to the center (100000), the brightness to the center (1000000), RGB cutoff to the center
(10000000), the Y mute to OFF (0), and connect an external power supply to #54.
Increase the supply voltage from V
When the #13 voltage stops changing, substitute the supply voltage (V) in the formula below and calculate DR
