I am trying to use the ADP1660 LED flash driver to driver 2 LEDs at independent mode. Here is my i2c registers configuration value:
0x01 0xBD (<---- mode setting)
0x06 0x08 (<---- LED1 flash current setting)
0x07 0x00 (<----- LED1 TxMASK current setting)
0x09 0x08 (<---- LED2 flash current setting)
0x0A 0x00 (<----- LED2 TxMASK current setting)
By using the hardware strobe input pin and GPIO pin, i can turn on/off the LED1 or LED2 respectively(according to the datasheet page 13).
However, i found that when I set "high" to the strobe input, LED1 and LED2 will light up at the same time, with the LED2's intensity is lower. Same situation happen if I apply "high" to GPIO, LED2 and LED1 both light-up, with LED1 is dimmer.
So, I would like to know if there is any wrong value in the above setting for independent mode? or there is a configuration sequence in order to get the independent mode?
Thank you very much
