SN75DP130: Is there a corresponding SDK available for SN75DP130

Hi Teams,

Is there a corresponding SDK available for SN75DP130?

The customer followed the instruction sequence for writing DPCD in the reference manual, but all read values were 0. So he's not sure if he was writing it correctly.

    Hi,

    There is no SDK available for DP130. 

    Access to and from the DP130’s DPCD address space is indirectly addressable through the local I 2C registers as illustrated below,

    The configuration of these registers can be performed through the local I 2C interface, where three registers (from 1Ch to 1Eh) are used as the address to the DPCD register and another one (1Fh) as data to be read/written.

    Thanks

    David
