Smart communication interface for LED matrix control
A smart communication interface for a LED driving system driving a LED matrix having a plurality of LEDs. The smart communication interface may have a data write transaction structure in write mode. The data write transaction structure includes an address code for identifying a corresponding one LED among the plurality of LEDs; an R/W indicating code for indicating whether the smart communication interface is in write mode; and a grayscale command code for indicating a programmed grayscale command value for the corresponding one LED identified by the address code. The smart communication interface may include a data read transaction structure in read mode. The data read transaction structure includes the address code, the R/W indicating code and a grayscale read-back code for indicating a grayscale command value for the corresponding one LED identified by the address code.
