LP5569: Register settings

Dice-K

Part Number: LP5569

Hi support team,
I have a question about register settings.

I am gathering information from the device's D/S and EVM documents, accessing the LP5569 from the MCU via I2C, writing commands to the SRAM, and running it, but the RGB LED does not light up.

What I tried:
The board is equipped with LP5569 and RGB LEDs on LED0-2.
The following contents were implemented using I2C access from MCU (Qualcomm IC).

table[2][32] = {...} //Data set written to SRAM 64byte

Write (0x00, 0x00)
Write (0x00, 0x40)
Write (0x2F, 0x58)
Write (0x02, 0x00)
Write (0x16~0x1E, 0x00) //LED0_PWM to LED8_PWM
Write (0x02, 0x40) //ch1_mode : Load program to SRAM
Write (0x4B, 0x00) //start addr
Write (0x4F, 0x00) //page0
Write (0x50, &table[0][0]) //burst write 32byte
Write (0x4F, 0x01) //page1
Write (0x50, &table[1][0]) //burst write 32byte
<-- dump -->
Write (0x02, 0x00)
delay 5ms
Write (0x02, 0x80)
Write (0x01, 0x80)

・As a result of dumping, the value of table[] was written correctly on page0 and page1.
・The LED will not light up after performing the above register settings.
・If I write any value to LED0_PWM, LED1_PWM, LED2_PWM, the LED will light up, so I think there is no problem with the HW.

Are some register settings missing?

Regards,

    Hi Dice-K,

    Could you please tell me the some detail application since I'd like to recommend our new device, LP5813, the next generation of LP5569, to you?

    For your question, please refer the below step to light up one LED for LP5569.

    Write 0x40 to register CONFIG <0x00>  --- to enable this device

    Write 0x59 to register MISC <0x2F> --- to enable charge-pump and internal oscillator

    Write 0xFF to register LED0_PWM <0x16> --- to turn on the LED

    BR, Jared

    Hi Jared,
    Thank you for the information.
    However, I have already confirmed that I can directly hit the PWM register to light up the LED.
    What I want to know this time is whether there is something missing in the register settings because the LED pattern does not light up even though I intend to run the Engine after writing data to SRAM.

    Please continue to support me.

    Best regards,
    Dice-K

    Hi Dice-K,

    The next generation of LP5569 has a completely new IP for animation engine and it's much powerful and useful than LP5569.

    For the animation control of LP5569, please refer the below code.

    	# Enable chip

	# Set engine 2 to Hold / Load Program
