LP5569: Independent mapping for simple breathing effect

Part Number:LP5569

Hi all,

I am still struggling to extend a simple LED breathing effect to different mapping options. Our application has the following LED outputs

LED1 - Connected to a white LED_A

LED2 - Connected to a white LED_B

LED3 - Connected to a white LED_C

LED4 - Connected to an RGB LED_D (R)

LED5 - Connected to an RGB LED_D (G)

LED6 - Connected to an RGB LED_D (B)

LED7 - Connected to an RGB LED_E (R)

LED8 - Connected to an RGB LED_E (G)

LED9 - Connected to an RGB LED_E (B)

I want to use a very simple engine that creates an infinite breathing effect and associate it with the different 5 LEDs flashing white, one at a time. Please note that LED_A, LED_B and LED_C will activate one line and LED_D and LED_E will activate 3 lines each. I will then need 5 different LED mappings associated to engine 1. Can the mapping be changed dynamically?

The program is something along the following lines:

.segment program1

map_addr led_a (it works if I define a dw instruction with one LED combination)

set_pwm 0

loop1:

ramp 1, 100

ramp 1, -100

wait 0.3

branch 0,

loop1 end

My question is, how can I define the mapping of the 5 different combinations I want to generate independently?

Thanks for your help
