More Information
Summary:The invention provides an LED driving cascade circuit and a cascade method thereof. The LED driving cascade circuit comprises a channel setting, a data decoding A, a data decoding B, a data path selection, a data register, an output driving circuit and the like. The cascade method includes the interconnection relationship of the LED driving circuit in the application and the corresponding data structure disclosed by the invention. The data structure comprises a reset code, a start code, a parameter and gray data. The LED driving circuit has two data input terminals of AI and BI. The data decoding A and the data decoding B respectively judge whether the input data of AI and BI are normal or not, and output the resultant AC and BC signals to a channel setting circuit. The channel setting circuit sets the control signal SEA according to the states of the AC and BC signals. The data path selection circuit sends the data of the normal channel to the data register under the action of the SEA, and the data output DO
