How Color Set Mode sets

Part Number: LP5024

Tool/software: TI C/C++ Compiler

Among the methods to use LP5024 are Bank Mode and Color Set Mode, and Bank Mode did RGB LED control.
I'm not trying to control the Color set mode.
I modified the example program provided by TI, but it doesn't work.

Can you give me some advice?

    It seems you want to change the color independently.

    So please first LED_CONFIG0 as 00h and you can use OUTx_COLOR register to set the color.

    My settings are as follows.

    LP5024_Chip_Switch(0x40);
     _delay_ms(1);

     LP5024_Mode_Select_Normal();

     LP5024_Device_Config1(0);
     LP5024_LED_CONFIG0(0x00);
     
     LP5024_LED_Color_Set(1, 255, 0 ,0);      // RGB LED1
     LP5024_LED_Color_Set(3, 0, 255 ,0);     // RGB LED3
     LP5024_LED_Color_Set(5, 0, 0 ,255);     // RGB LED5
     LP5024_LED_Color_Set(7, 255, 255 ,0); // RGB LED7

    And when you turn on the LED in Bank Mode, the LED goes off the first few times.

    Do you have any idea why?

    I wonder if it has anything to do with the setting.

    Thank you for your interest in my writing.

    Hi,

      If you want to change the color independently, please set the LED_Global_Off bit to 1 when you finished your selected channel setting. If you want to use the bank control mode, you should set the BANK BRIGHTNESS and BANK_X_COLOR register according to your lighting pattern, and then enabling the corresponding LEDX_BANK_EN bit in DEVICE_CONFIG1 register.

      In your code, you just set the brightness and color of channel independently, rather than BANK BRIGHTNESS and BANK_X_COLOR register. So when you turn on the LED in Bank Mode, the LED maybe goes off the first few times.
