Universal embedded servo controller

The invention relates to a universal embedded servo controller, and belongs to the technical field of embedding, the universal embedded servo controller comprises a DSP module, a 1553B communication module, a synchronous 485 communication module and a first AD input module; the 1553B communication module, the synchronous 485 communication module and the first AD input module are all connected with a parallel port bus of the DSP module; the priority of the 1553B communication module and the synchronous 485 communication module using the parallel port bus is higher than that of the first AD input module by controlling the use authority of the parallel port bus of the DSP module; in the process that the first AD input module uses the parallel port bus to transmit data, when the 1553B communication module or the synchronous 485 communication module uses the parallel port bus, the first AD input module stops using the parallel port bus until the 1553B communication module or the synchronous 485 communication modul
