LP5562EVM: Using engines to pulse orange

Part Number: LP5562EVM

Hi,

I am trying to use the engines and to pulse orange color over and over again.

This is the code that I am using:

# engine 1 section start
.ENGINE1

# engine 2 section start
.ENGINE2
ramp 500, 128
wait 300
ramp 500, -128
wait 300

# engine 3 section start
.ENGINE3
ramp 500, 70
wait 300
ramp 500, -70
wait 300

Engine 2 is assigned to Red and ENGINE3 to Green. Blue is I2C controlled.

The problem is that the LEDs are not blinking in the same time. As I can see, red is the first one that starts to blink and green is after it. Does the engines execute the code in the same time for all 3 engines or does it execute it sequentially (one engine after another)?

Regards,

Gabriel

    You can refer to 7.3.3.4.6 Trigger, "Wait or send triggers can be used to synchronize operation between different engines."

    Please use trigger as following:

    # engine 1 section start
    .ENGINE1

    # engine 2 section start
    .ENGINE2
    trigger s3
    ramp 500, 128
    wait 300
    ramp 500, -128
    wait 300
    trigger w3

    # engine 3 section start
    .ENGINE3
    trigger w2
    ramp 500, 70
    wait 300
    ramp 500, -70
    wait 300
    trigger s2
