Part Number: LP5024

We are trying to enumerate LP5024 as I2C slave device in OS via BIOS. To do so we need to enter HW-ID.

Is the HW-Id for the slave controller = “LP5024” or “TILP5024” or something else? Any idea?

Thanks

Hi Eshak,

You could directly use I2C to control LP5024. We do not have HWID for it.

If needed to access the device via OS using device enumeration , we need to include HW ID in the code.

Hi Eshak,

What hardware you used with LP5024? I am not familiar with the control way by OS. But I think if you are using I2C as interface via BIOS, HW ID is no need for it. You can find I2C address in datasheet section 8.5.1.4

Hi Hardy

We are trying to write a api code that communicates with the I2C driver in windows system. To do so we need to enumerate the I2C device so it is detected in device manager. something like below,

Thanks

Hi Eshak,

Sorry we do not have driver code based on windows. Usually we use GUI connect to device in windows environment.
