LED blinking patterns(square , triangle, pulse ) with different intensity using led drivers like LP5523 and LP55281

Other Parts Discussed in Thread: LP55281, CC2650, LP5523, LP5523EVM

am working on generating different blinking LED patterns on LP55281 and LP5523 by connecting it with I2C to CC2650 devkit

I don't have driver support for LP55281 .could you please help in this regard whether we have a driver support for LP55281 or we have to start writing on driver.

and am working on the storing the LED patterns in RAM or userpage or external flash .

currently am generating patterns using pwm by increasing duty cycle for single LED with clock sync

but in EVM we have 12 LED's white and RGB ,,,can you help me how to generate pattern using all LED's at one shot blink in same time

thanks in advance !!!!!!!!!

Hi,

Unfortunately TI has no driver for the LP55281 so you need to write your own drivers.

Can you describe your problem more in detail? With LP5523EVM you can use jumpers J10-J12 to select RGB or white LEDs but not all 12 physical LEDs (18 LED dies) simultaneously as there's only 9 LED drivers in the LP5523.

BR,
Jussi
