Abstract

The invention relates to the technical field of message sending and receiving, and discloses a periodic and non-periodic mixed communication method for low-speed serial bus. Send once per cycle, and aperiodic messages are sent when an emergency occurs; analyze whether the data message is sent at this time, whether there will be a conflict, and if so, the data message is temporarily stored in the cache Buffer; the server side When receiving the sending command, the flag bit Flag is set to 0, and after receiving the data message, set to 1; judge the sub-message type according to the Resp value, if it is the periodic message, then update the data, if it is the Aperiodic packets are written to RespBuffer. In the present invention, by setting the Buffer and the Flag, the periodic message and the non-periodic message are serially sent and received to prevent the conflict between the two, and quickly perform corresponding processing on the two.

Description

technical field [0001] The invention relates to the technical field of message sending and receiving, in particular to a periodic and aperiodic mixed communication method and system for a low-speed serial bus. Background technique [0002] Client data needs to be uploaded to the server for updating. Data upload can be done in serial and parallel ways. In general, in order to avoid waste of resources, when frequent data upload is not required, most of the data is completed in serial mode. upload. Serial data transmission is more convenient for periodically sent data packets due to the single sending port, but it is easy to cause data conflicts and errors for bursty data packets. [0003] At present, periodic and non-periodic mixed communications transmit data. In order to solve the problem of serial transmission data conflicts, a clock is generally set at the serial port to specify and time the transmission time of each data message. However, the specified time Generally, i...
