LP5812: LP5812 application information

Hi Timo,

Please refer the programming demo below:

• Manual mode
  1. Set chip_en = 1 to enable the device. (Write 01h to register 000h)
  2. Set led_mode = 0h to configure the LED drive mode as direct drive mode. (Write 00h to register 002h)
  3. Send update command to complete configuration settings (Write 55h to register 010h)
  4. Enable 4 LEDs (Write 0Fh to register 020h)
  5. Set manual_DC value (Write 55h to register 030h~033h)
  6. Set manual_PWM value (Write FFh to register 040h~043h)
• Auto mode
  1. Set chip_en = 1 to enable the device. (Write 01h to register 000h)
  2. Set led_mode = 0 to configure the LED drive mode as direct drive mode. (Write 00h to register 002h)
  3. Set auto_en = 1 to configure the LED in auto mode. (Write 0Fh to register 004h)
  4. Send update command to complete configuration settings (Write 55h to register 010h)
  5. Enable 4 LEDs (Write 0Fh to register 020h)
  6. Set auto_DC value (Write 55h to register 050h~053h)
  7. Set LED_0_Autonomous_Animation value
  8. Set the same value for LED_1_Autonomous_Animation (Write 00h, 00h, 00h, FFh, 00h, FFh, 00h, AAh, AAh to register 09Ah~0A2h)
  9. Set the same value for LED_2_Autonomous_Animation (Write 00h, 00h, 00h, FFh, 00h, FFh, 00h, AAh, AAh to register 0B4h~0BCh)
  10. Set the same value for LED_3_Autonomous_Animation (Write 00h, 00h, 00h, FFh, 00h, FFh, 00h, AAh, AAh to register 0CEh~0D6h)
  11. Send update command to complete configuration settings (Write 55h to register 010h)
  12. Send start command to start the engine animation (Write FFh to register 010h)
