PCA9635 LEDOUT0 to LEDOUT3 - LED driver output state register

LDRx = 00 — LED driver x is off (default power-up state).

LDRx = 01 — LED driver x is fully on (individual brightness and group dimming/blinking

not controlled).

LDRx = 10 — LED driver x individual brightness can be controlled through its PWMx

register.

LDRx = 11 — LED driver x individual brightness and group dimming/blinking can be

controlled through its PWMx register and the GRPPWM registers.

我编程验证00是开……01是关…… 你们呢?
