Abstract

The embodiment of the invention discloses a multichannel adaptive baud rate communication method and device, electronic equipment and a storage medium, and the method comprises the steps: adjusting the current mode of a transmitting end to an open-drain output mode when the transmitting end transmits data to a receiving end, and transmitting a wake-up signal to the receiving end in the open-drain output mode; if a confirmation signal sent by the receiving end based on the wake-up signal is received within a preset time interval, adjusting an open-drain output mode to a pull-up input mode according to the confirmation signal, and determining a data stream sending mechanism according to the confirmation signal under the pull-up input model; sending the data stream to a receiving end according to the data stream sending mechanism, so that the receiving end receives and processes the data stream; and obtaining a sending state of the data stream, and sending an ending signal to the receiving end according to the sending state. The method does not depend on absolute time signals, the problem that equipment cannot communicate due to the difference of communication peripheral clocks is solved, and the stability and reliability of communication are improved.
