Abstract

This invention provides a communication method, apparatus, electronic device, and storage medium based on SPI simulating PECI, relating to the field of communication technology. The method includes: generating SPI data corresponding to first PECI data according to preset high-level and low-level duty cycles; sending the SPI data to a slave device via a data line; receiving voltage-converted data obtained by voltage conversion of second PECI data via a data line according to a preset PECI data period; the second PECI data being data sent out by the slave device; sampling the voltage-converted data according to a sampling period to obtain SPI sampled data; and obtaining the second PECI data based on the SPI sampled data, the high-level duty cycle, and the low-level duty cycle. This invention enables PECI data communication without consuming significant CPU resources or increasing equipment costs.
