Part Number: TLC59208F

I would like to adjust LED brightness by changing duty of PWM.

However, I saw Table 9 of datasheet, the figure shows that default value is 00 which means LED driver is off.

Regarding to following figure, Should I change LEDOUT0 or 1?

Best regards,

Hi, Koyo,

That's correct.

Please set LDRx=10 to make sure "individual brightness can be controlled through its PWMx register".

So for LEDOUT0/LEDOUT1, please send 0b10101010 (0xAA).

Please help to click "Resolve" if the problem is solved.

Thanks.
Regards,
Kenneth
