TLC5947 Serial daisey chains.

Other Parts Discussed in Thread: TLC5947

Hello,

When using the serial interface port, Do you have to send the entire PWM duty cycle to all the outputs when only wanting to change the PWM on selected outputs.

 Planned MCU  is  430xx with 10x TLC5947 controlling 50 RGB smd.

As an  example say all LEDs are set to white (4096,4096,4096) pwm and I only need to change 1 RGB to RED (effectively 4096,0000,0000) do I need to send the entire 50 led pwm again or can it be coded to just change that LEDs group output PWM.

My intent is to use the auto repeat function for the RGB groups that dont need to be changed or does this function operate on a chip level not an individual output level.

Thanks in advance,

Daniel
