Hi, wade

pls follow the user guide to setup the device.

Can you tell me VDDEXT I Connected external supply is 3.3v ,and R34,R37  Connected 0 ohm is not right?

i try let VDD=5V and VDDEXT=5V Always appear flicker phenomenon and GUI appear hardware not connected

Hi, wade

If you used 3.3V, charge pump is needed.

if you see the flicker, pls check with the power capability of the input power.

now appears

Hi, wade

For LP8864, the addres is 0x3A and 0x3B, you can find it in the datasheet.

LP8866 is 0x2A and 0x2B.

the datasheet also tells you how to change it.
