LP5036: Bring up LEDs to a basic pattern as soon as power is received to the board.

Part Number: LP5036
Other Parts Discussed in Thread: LP5569
Hi TI,
We are using the LP5036 to indicate different instrument states.
Our intention is to bring up the LEDs as soon as power is delivered to the board.
The registers get reset upon initialization.
We are looking for LEDs to come up (with any pattern) as soon as power is supplied instead of waiting for commands from our application.
What are the possible ways to turn on LEDs as soon as power is delivered?
1. Is there a way to change the reset behavior upon initialization?
2. Can the default values of the registers be changed at initialization? 
3. If none of the above options are available, please recommend a different board that supports our needs.
I have another question - 
Are there more patterns that can be done using bank mode apart from Breathing and Blinking. I understand how the bank mode works but I was hoping to get an insight on more patterns and ideas which you may have already used/seen as we want to focus on using patterns which use Bank mode for our CPU utilization problems.
For example, breathing pattern also needs to loop 255 times to create the effect. This may be heavy on our CPU. 
Or are there any boards or hardware which can perform more patterns using bank mode? 
Thank you in advance for your help. :) 
  • Hi Ankita,

    Sorry there is no solution to change reset behavior and default value, and all of our RGB LED drivers need I2C commands to be illuminated.

    LP5036 do not have any integrated pattern so that animations need to be controlled by user program. Bank function let user control several channels in one command having the same behavior, to lighten some load of controller. But basically, the controller need to send commands real time to achieve patterns.

    We have some device with engine function, like LP5569, which can run patterns with simple commands. But this function have not been defined into high-channel-number device yet. How much RGB LEDs and output current you need for your application?

  • Thank you for the suggestion. 

    We need at least 8 RGB LEDs for our application and the output current it 20mA.
