Led control system, device, method and storage medium

A data transmission method applied to any light emitting diode (LED) driver of a plurality of cascaded LED drivers, wherein the LED driver comprises a bypass switch, and the method comprises:

• acquiring a data signal from a controller or a previous LED driver, wherein the data signal comprises data packets corresponding to the plurality of LED drivers arranged in sequence, and each LED driver corresponds to a data packet that comprises control data and an end bit corresponding to the LED driver;
• after control data of a preset length is acquired, detecting whether the end bit is a preset value;
• if the end bit is the preset value and there is a next LED driver, setting a bypass flag to a first state value;
• wherein when the bypass flag is the first state value, the bypass switch is turned on to transmit a data signal after the end bit to the next driver;
• when the bypass flag is not the first state value, the bypass switch is turned off.

A data transmission method, applied to a controller, comprising:

• determining a data signal corresponding to a plurality of cascaded light emitting diode (LED) drivers, wherein the data signal comprises data packets corresponding to the plurality of LED drivers arranged in sequence, and each LED driver corresponds to a data packet that comprises control data and an end bit corresponding to the LED driver;
• sending the data signal to the plurality of cascaded LED drivers, to enable the LED driver to acquire control data of a preset length from the controller or a previous LED driver, and detecting whether the end bit is a preset value;
• if it is detected that the end bit is the preset value and there is a next LED driver, setting a bypass flag to a first state value;
• wherein when the bypass flag is the first state value, the bypass switch of the LED driver is turned on to transmit a data signal after the end bit to the next driver;
• when the bypass flag is not the first state value, the bypass switch is turned off.
