STMPE16M31PX
The registers need to be programmed for this sequence :
– On Period = Period 0[1:0] * Time Unit [3:0]
– Off Period = Period 1[1:0] * Time Unit [3:0]
– Duty cycle during On Period = Brightness [7:4]
– Number of cycles = Repetition [3:0]
– Ramp-Mode is enabled
– Ramp Up/Down Rate is programmable
