The invention provides a communication method and system among one-master multi-slave single-chip microcomputers and a storage medium, and the method comprises the steps: determining a target slave single-chip microcomputer which is a slave single-chip microcomputer communicating with a master single-chip microcomputer and is a first type of slave single-chip microcomputer or a second type of slave single-chip microcomputer, the MISO ports of the first type of slave single-chip microcomputers are configured to be push-pull output, and the MISO ports of the second type of slave single-chip microcomputers are configured to be open-drain output; target data sent by the target slave single-chip microcomputer is received, the last byte of the target data is a high-level signal, when the target slave single-chip microcomputer is the first type of slave single-chip microcomputer, the second type of slave single-chip microcomputer is in a high-resistance state mode, and when the target slave single-chip microcomputer
