Hello, we prepared a LED- illumination board with the LP5864 and 4x 5 RGB- LEDs (4x 15 lines) and want to drive the LEDs via 8bit PWM. We have access to the register area via I2C e.g. read "Dev_initial" = 5Eh.
Can you give me an initialisation setup (control registers) and the address where the 1st LED can be controled via a 8bit PWM value and 20mA ?
many thanks for your support!
with best regards Michael
Hi Michael,
If you want to get 20mA output current, there are a lot of configurations to achieve this and here is one of them:
1. Set the Maximum_Current to 04h in Dev_config3 Register (0x06)
2. Set the DC0 Register (0x100) to FFh
3. Set the pwm_bri0 Register (0x200) to FFh.
After configuring these 3 registers, then light up the LED dot, I think you can get 20mA output current.
