hi all:
first I config address 0 to 0x1h to enabled LP5569. and set Led0_control_register ~Led8_control_register 0x4 ,LED is Powered by external power source . and then I want to set a value to LED0_PWM(16h) regitser, but it can not set success,the read value of address 16h is still 0. The values of the other registers can be read and written normally. the en/pwm pin is high level. Now the light doesn't light up. I want to ask where the problem is?
thanks!
