LED module driving method, display system and computer storage medium

The invention relates to an LED module driving method, a display system and a computer storage medium. The method comprises the following steps: acquiring SDI data on a serial bus of a single IO port in a row scanning LED driving data set; obtaining the first N bits of the current byte, placed in the QSPI/OSPI data segment, of the current bits in the SDI data, and obtaining the last N bits of the current byte, placed in the QSPI/OSPI data segment, of the next bits in the SDI data; performing shift processing on the SDI data, and determining a current bit based on a result of the shift processing; acquiring the next byte of the QSPI/OSPI data segment as the current byte, and continuing to execute the steps until the SDI data are all placed in the QSPI/OSPI data segment; and sending the QSPI/OSPI data segment to a driving chip through a QSPI/OSPI protocol. By adopting the method, the utilization rate of the MCU resources can be improved, and the waste of the MCU resources is reduced. 本申请涉及一种LED模块驱动方法、显示系统和计算机存储
