Hi,

I have a question about LED Current Setting I2C Command (54h).

I think I'd like to set the current [mA] using I2C Command (54h).

How can I calculate the value to set using the 54h command?

Regards,

Goto

Hi Goto,

The value is calculated according to the PMIC specification. In DLP4710EVM-LC the PMIC is DLPA3005. Kindly check DLPA3005 datasheet section 7.3.2.4 RGB Strobe Decoder for the relationship between the 10bit value and the LED current.

Thanks & Regards,
Hirak.
