I am able to read and write the configuration registers on the LP55231 over I2C, using an Atmega microcontroller.
After going through the datasheet, it is not clear to me what sequence of instructions is required to light up the LEDs.
Can anyone who has successfully used this IC tell me the sequence of reads/writes that should be performed?
(I have tried setting CHIP_EN to 1, and then setting OUTPUT ON/OFF CONTROL (reg 0x05) to hih for the corresponding LEDs. however, no success)
