Image Mode

Power-On Sequence

After power-on, wait T

s for APDS-9500 to stabilize. Then, write slave ID (0x73) to process I

C wake-up. After T

s,

write the initial settings. Lastly, enable APDS-9500 by writing Register Bank1, Addr0x72 with 0x01 and then enable the

SPI output by writing Register Bank 1, ADDR 0x7E with 0x01. The image data can now be accessed through the SPI bus.
