DLPC3430: I2C addressing

Part Number: DLPC3430

Hi,

Is there any method to change the I2C address of the device to enable multiple DLPCs to be driven from a single I2C bus, from an FPGA for example?

Kind Regards,

Hello Stephen,

I have a quick question realted to your query.

Which EVM platform are you using for your application and for which application you want to change I2C address of the device.

Thanks,
Navneet

HI Navneet,

We are doing some testing on DLP2010 Lightcrafter, but I'm asking his because I'm working on a design that has several DLP chipsets on the same board, and being able to use the same I2C bus to talk multiple chipsets would save on the number of traces on the board, as well as pins on the FPGA that I'm using to drive thes.

Thanks again for all the help. It is greatly appreciated.

Stephen,

I2C address can't be customized. But if you need we can provide you the different firmware with new I2C address.

Thanks,
